Electronic Power Steering CHAPTER 6B: ELECTRONIC POWER STEERING NOTE: The basic steering system, such as the tie rod ends, drag links axles, etc., are covered in Chapter 6A: Steering. In 2011, Cub Cadet introduced the Electronic Power Steering (EPS) system on the Cub GTX2154LE (50th anniversary edition) tractor. The EPS provides an electric assist to the steering wheel. The EPS is a system consisting of three sub-assemblies: the rubber torsion coupling, the EPS module and the EPS motor & gearbox.
2000 Series Tractors EPS motor & gearbox The steering input passes through the torsion coupling and module into the gearbox. The gearbox then passes the input force to the output shaft connected to the steering housing. The EPS motor assists in turning the input shaft by driving a set of planetary gears. The planetary gears drive a worm shaft. The worm shaft drives a worm gear on the output shaft.
Electronic Power Steering Troubleshooting the EPS The first step in troubleshooting the EPS system is to understand how it works. See Figure 6B.4. • A constant 12 volts is supplied by the battery through a 40 amp fuse in the fuse box. ,JQLWLRQ PRGXOH • The EPS is grounded through the green wire. • The EPS senses the ignition pulses from the ignition module primary windings through the yellow wire with a white trace.
2000 Series Tractors 7. Locate, but do not disconnect the EPS harness connector behind the battery. See Figure 6B.6. 8. Check for battery voltage at the red wire: 8a. Set the Digital Multi Meter (DMM) to the DC volts scale. 8b. Measure the battery voltage across the battery terminals NOTE: If the battery voltage is < 12.6 volts, charge the battery before continuing. 8c. Connect the black (-) lead of the DMM to the negative post of the battery. 8d.
Electronic Power Steering 9f. Without sitting on the tractor, turn the steering wheel a quarter turn back and forth. Watching the voltage reading on the DMM and the current reading on the amp clamp while doing this. NOTE: If the voltage drops below 13 volts and the current does not rise above 10 amps, repair the circuit suppling voltage to the EPS before proceeding with troubleshooting the EPS system.
2000 Series Tractors EPS motor To remove/replace the EPS motor and test it: NOTE: The EPS system comes with a 4 year warranty. DO NOT remove the EPS motor to test it within the warranty period. Outside of the warranty period, the EPS motor can be replaced separately from the EPS assembly. 1. Remove the EPS assembly by following the procedures described in the EPS removal section of this chapter. 2. Disconnect the EPS motor harness. 3. Remove the two screws, indicated by the arrows in Figure 6B.
Electronic Power Steering 8. Inspect the EPS motor gasket. If it is damaged, replace it. NOTE: Do not use a gasket sealant/adhesive on the EPS motor gasket. 9. Remove the sun gear from the EPS motor. Sun gear 10. Install the sun gear into the planetary gear set. Figure 6B.12 Harness EPS motor pig tail 11. Install the EPS motor.

2000 Series Tractors NOTE: Lift the EPS out of the tractor. NOTE: The EPS output shaft will pass through a spacer, washer and the steering housing. See Figure 6B.25. NOTE: Install the EPS by following the previous steps in reverse order. Spacer NOTE: The washer that goes in between the pinion gear and the steering housing, must be held in place under the tractor while inserting the EPS into the steering housing. 22. Washer Test drive the tractor in a safe area before returning it to service. Figure 6B.
Electrical System CHAPTER 7: ELECTRICAL SYSTEM Introduction This chapter is divided into four sections: • Section 1: About this chapter and precautions • Section 2: Components • This section will describe the location and operation of the electrical components on the mower. Where appropriate, some disassembly or component removal instructions will be included.
2000 Series Tractors Key switch The Key Switch is similar to those used in a variety of MTD applications since 1999. The difference, in this case, is that it is incorporated in the same housing as the RMC module. The two items are not available separately. See Figure 7.1. 1. RMC Module Front In the “OFF” position, continuity can be found between the M, G, and A1 terminals. See Figure 7.2.
Electrical System 3. 4. • Symptom: Crank, spark, but no fuel: First check the fuel tank to verify that there is fuel in it. If there is fuel in the fuel tank, test for power at the afterfire solenoid. If there is no power there, then check for continuity from B to A1 in the START position. If power is reaching the red wire that connects to the A1 terminal in the start position, the problem lies down stream of the key switch.
2000 Series Tractors RMC Module RMC Module The RMC Module is in the same housing as the key switch and is not available separately. For the purpose of diagnosis, it is treated separately. Diagnosis of the module with the key switch introduces too many over-lapping variables. See Figure 7.3. • Principle: To diagnose the module, the simplest approach is to check all of the inputs (safety circuits) that are connected to it.
Electrical System To identify a faulty RMC module: Purple If the RMC module does not function as described, the RMC plug test should be the first step in diagnosis. Green • If the RMC plug test confirms that the safety circuits (inputs) work as designed, yet the RMC module does not work properly, the RMC module is faulty. Yellow/White Red/Black Red • The RMC plug test will give an indication of what the problem is if it is not a faulty RMC module.
2000 Series Tractors Red wire with black trace • Behavior: There is a red wire with black trace between yellow wire with a black trace and the green wire. This wire provides the module with input from the reverse switch. When the mower is in reverse, this terminal should have continuity to ground. • Circuitry: This wire runs directly to the reverse safety switch. This is a simple metal tang switch that groundsout against the hydro control rod.
Electrical System PTO Switch Understanding the PTO switch Figure 7.6 3. 1. A-COM is in the starter inhibit circuit. It is a normally closed (NC) set of contacts. Power coming from the brake switch (key switch in START, brakes ON) flows through the orange wire with black trace to the PTO switch. When the PTO is OFF, and the contacts are closed, the power continues through the orange wire with white trace to the trigger terminal on the starter solenoid. 2. B-COM is in the PTO relay latch circuit.
2000 Series Tractors Reverse Safety Switch The Reverse Safety Switch is a simple metal tang switch mounted on a bell crank of the drive pedal shaft. When the reverse pedal is depressed, the bell crank will rotate towards the rear of the tractor, pressing the reverse switch into the hydro control rod. See Figure 7.8. Hydro control rod Reverse switch Figure 7.8 Seat Safety Switch The Seat Safety Switch is mounted inside the seat. It contains two sets of N.O. contacts See Figure 7.9.
Electrical System Seat circuit (GTX2154LE) Most seat switches that MTD use are NC switches. This means that when the operator leaves the seat, the switch closes, allowing a ground signal to pass through it. However, the 50th anniversary edition (GTX2154LE) is equipped with a special high back seat. This seat comes equipped with a SPST NO switch. This means that when the seat is empty, the switch is open, blocking the ground signal. Seat switch connector Figure 7.
2000 Series Tractors Starter solenoid On Kohler Command engines, the starter solenoid is part of the starter. See Figure 7.13. • Starter Solenoid When the proper safety conditions are met (brake applied, PTO OFF), the orange wire with white trace carries battery power to the engine harness connector. At which point the battery power is transferred to a blue wire that carries it to the trigger terminal of the solenoid. Figure 7.

When the key switch is in the START position, battery power is passed from the B terminal to the S terminal. 2.
2000 Series Tractors Once the starter motor spins, we still need spark and fuel to make the engine run. Looking at the circuits that do that: 1. The ignition sparks are generated by an ignition module. The ignition module will work as long as the primary windings are not grounded. With the key switch in any position other than off, there is no connection between the M (Module) terminal and the G (Ground) terminal. See Figure 7.17.

2000 Series Tractors Engine shut-down circuits Engine shutdown circuits stop the engine by disabling the ignition and removes power from the afterfire solenoid. .H\ 6ZLWFK * Key switch shut-down: See Figure 7.22. $IWHUILUH 6ROHQRLG % *URXQG )XVH 0DJQHWR The A1 terminal is de-energized. 6ROHQRLG NOTE: On older electrical system, prior to 2008, the afterfire solenoid was powered by the alternator.
Electrical System Charging circuit How it works Stator 1. When the engine is running, magnets attached to the underside of the flywheel induce A.C. (Alternating Current) in the stator that is mounted beneath the flywheel. See Figure 7.24. 2. The A.C. travels from the stator to and from the regulator/rectifier through the two white wires. NOTE: The magnets inside the flywheel act as a rotor for the charging system. Rotor (magnets in recess) Figure 7.24 3.
2000 Series Tractors 5. From the harness connector: See Figure 7.26. .H\ 6ZLWFK 5a. The red/white trace wire leads to the 20A fuse. 5b.

Electrical System 5. Figure 7.28 Stator check: See Figure 7.28. 5a. Key OFF, unplug the stator from the regulate/ rectifier. 5b. Check resistance through the stator using a digital multimeter set to read Ohms. • It should be between 0.1Ω and 0.14Ω. • A high reading indicates a fault in the windings. • A low reading indicates a short in the windings. • There should be a reading of O.L. (Open Line) between either lead and the engine block.
2000 Series Tractors 6. Regulator/rectifier check: See Figure 7.30. 6a. Check the ground. • With the engine running and the stator leads reconnected to the regulator/rectifier, perform a ground-side voltage-drop test from the regulator/ rectifier to the engine block. • If the voltage reading is greater than 0.1 Volts D.C., replace or properly fasten the ground wire that connects the regulator/rectifier to the engine block. Retest to confirm good connection. Figure 7.30 6b.

2000 Series Tractors PTO Circuit .H\ 6ZLWFK ³5XQ´ Basic Operation: See Figure 7.33. 1. 3. • When the mower is put in Reverse, we want to turn off the blades unless the RevTec (RMC) module has been armed and engaged.

The set with the yellow wire leads to ground when the contacts of the seat switch are closed. See Figure 7.34. 2a. When the operator leaves the seat, the seat switch connects the yellow wire to a ground path. 2b. That ground path passes through the RMC module to ground the PTO relay windings when the mower is put in reverse.
2000 Series Tractors Reverse Mower Control (RMC) circuit operation Historically, Cub Cadet residential mowers have not been able to mow in reverse. This has not been required by any laws or safety regulations, it was just safer for our customers and those around them. Then in 2005, ANSI regulations for residential mowers were changed, requiring that the mowing blades turn off when the mower was put in reverse. The new standard did allow for a user controlled over ride system.
Electrical System When the RMC module is armed and activated, it effectively disconnects the reverse switch from the circuit. See Figure 7.38. .H\ 6ZLWFK ³5XQ´ $ * / 6 $ The RMC module is disarmed and de-activated when the seat is vacated; it gets a ground signal through the second set of contacts in the seat switch.
2000 Series Tractors Deck lift circuit KDUQHVV FRQQHFWLRQ Basic Operation: See Figure 7.39. 1. Battery power goes through the top 30A fuse in the fuse box. It then flows through the orange wire until it reaches the deck lift harness connector. It then passes onto the red wire with a white trace. The red white with a white trace carries the power to the N.O. contacts of the deck lift relays. 2. Both of the deck lift relays have the N.C. contact connected to ground.
Electrical System Electrical diagnosis NOTE: Electrical diagnostic procedures and tools are the same for all Cub Cadet and MTD mowers. This section is written in a way to provide basic trouble shooting skills that can be used on any mower. With a basic understanding of the behavior of electricity and the tools used to measure that behavior, a technician can be about 80% effective at finding electrical problems.
2000 Series Tractors • Low Voltage: Many electronic devices simply stop working if system voltage falls below a given threshold. If a 12 volt system is run at 11 volts with a failing alternator, electronic controls may stop working. • Bad Grounds: Bad grounds can reduce the effective system voltage, create resistance and heat, and send false signals. This is the single most common breeding ground of electronic gremlins. • Heat and Vibration: Heat and vibration are hard on most mechanical devices.
Electrical System Ohm’s Law Ohm’s Law relates voltage, amperage, and resistance. It states that voltage is the product of resistance times current. • It is written as V = I x R. • In simplest terms, it goes like this: V • It takes 1 volt to push 1 amp through a resistance of 1 ohm (1 = 1 x 1). R I Figure 7.40 • This equation can be rearranged using algebra to solve for any one variable. • Those who were traumatized by algebra can represent Ohm’s law as a triangle.
2000 Series Tractors Kirchhoff’s voltage law Kirchhoff’s voltage law deals with voltage drops. A voltage drop is the amount of voltage used up or “dropped” by resistance in a circuit. Ohm’s law states that V = I x R, every component in a circuit has resistance, even the wires. To push current through resistance, it takes voltage. Kirchhoff’s voltage law states that the sum of all the voltage drops equals the source voltage.
Electrical System Types of circuits There are three ways a circuit can be wired: • Series • Parallel • Series/parallel Series Series circuits are wired so that the current has only one path to follow. If one component in the system fails, the circuit will be broken and whole system will not work. See Figure 7.43. Switch Lamp Battery Figure 7.43 Parallel Lamp Battery Parallel circuits are wired so that current has multiple paths to follow.
2000 Series Tractors Series/parallel Series/parallel circuits have some sections wired in series and some in parallel. See Figure 7.45. Lamp Battery Lamp Lamp Lamp Switch Figure 7.45 What can go wrong? There are three types of failures that can occur in an electrical circuit: 1. Shorts 2. Opens 3. Increased resistance Shorts A short is when electricity takes a path that it was not designed to take by-passing a component in the circuit.
Electrical System The Tools Equipment needed to diagnose an electrical system: • DMM (Digital Multi-Meter) • Wiring schematic or diagram Equipment that may be useful: • Fused jumper wires. • Test light • Self-powered continuity light • Ammeter • Battery charger • Battery tester • Battery jumper cables • Hand tools to gain access to components. • Flashlight.
2000 Series Tractors Digital Multi-meter A DMM is the most useful tool to troubleshoot any electrical system. There is an amazing variety of DMMs on the market. Some are very basic, others are tailored to specific industries, and some high-end graphing meters function like oscilloscopes. Even the most basic ones are quite versatile. See Figure 7.46. Uses Voltage Set meter to read “Volts DC (_ _ _)” if using an autoranging meter or to an appropriate scale (typically 20 Volts DC) if using a more basic model.
Electrical System Wiring diagram or schematic A wiring or a schematic diagram, and the ability to read it are very important in troubleshooting a circuit. The diagram shows how the circuit was designed and what paths the electricity is suppose to flow. Fused jumper wires Fused jumper wires are handy to help find bad grounds or to jump across switches for testing purposes. ! CAUTION Only use fused jumper wires.
2000 Series Tractors Ammeters and specialized charging system testers Inductive ammeters or “amp clamps” are available in many forms. Some are as simple as a gauge to be held against the circuit in question when it is energized. The operating principle is based on magnetic field induced by the current flow. See Figure 7.48. DMM with inductive ammeter feature Inductive ammeter There are two primary reasons to measure amperage. The first is to check the output of a charging system or battery.
Electrical System Batteries Batteries produce flammable and explosive gases, particularly during charging. ! CAUTION • Do not smoke or allow an open flame or heat source near the battery. • Charge batteries in an open area • Wear eye protection and acid resistant gloves when handling batteries. • Do not allow direct metal contact across the posts. This will produce extreme heat that may cause direct burns or ignite flammable gas.
2000 Series Tractors Checking battery condition There are three things to do when testing a battery: 1. • Visual inspection • Electrolyte test • Operational test Visual inspection • Inspect the battery and battery connections for corrosion. Clean if necessary. Neutralize acid with baking soda, and protect the terminals once they are cleaned. NOTE: Battery cable corrosion is the most common type of increased resistance circuit failures.
Electrical System Battery Testers There are four major ways to check a battery: • Electrolyte test using a specific gravity tester (hydrometer) to compare the density of the electrolyte in a fully charged battery to the density of water (water = 1.0 s.g.). • Electrolyte test using a refractometer to check the density of the electrolyte by measuring the degree to which light waves bend when passing through the electrolyte.
2000 Series Tractors Fixed load testers Fixed load testers (sometimes called toasters) are inexpensive load testers found at any auto parts store. See Figure 7.51. NOTE: Because they have a fixed load value, they do not give most batteries a reliable and safe load test. Most fixed load testers have a load that is more than 50% of the rated CCA of riding mower batteries. This makes them inappropriate to use on smaller pieces of outdoor power equipment.
Electrical System Battery discharge test Occasionally a battery will discharge while sitting unused. To test for a battery that is “leaking” voltage: Figure 7.53 1. Confirm that operator technique is not creating a situation that cases a draw. As an example, if a homeowner habitually turns their equipment off using a safety switch (perhaps vacating the seat with the key switch still ON), that may leave a relay or fuel shut-off solenoid energized. 2. Disconnect and charge the battery fully. 3.
2000 Series Tractors Electrical Troubleshooting 1. The first step in troubleshooting is to always verify the complaint. Defining and verifying the problem reduces the possibility of misunderstanding and helps clarify the diagnostic approach. 2. The next step is to check the simple stuff first: • Check the fuse or fuses: NOTE: Failure of any fuse is an indication that there is a problem of some sort in the circuit that the fuse protects. • Look for obvious physical damage.
Electrical System 6. Starting with a fully charged battery and battery cable connections that are clean and tight, measure the battery voltage. See Figure 7.54. 7. With the circuit energized, start at either end of the circuit and check for voltage. • If starting at the battery end of a powered circuit, trace it through until power vanishes. • If starting at the ground end of a powered circuit, trace it through to the point that power appears. Figure 7.
2000 Series Tractors Voltage Drop Test To review: • Ohm’s law states that it takes voltage to push current through a resistance. • Kirchhoff’s voltage law states that the sum of all the voltage drops equals the source voltage. • Combining those two laws, we see that any restriction in a circuit (e.g.: loose connector damaged wire, or corroded terminal) will use up some voltage as the current is pushed through. • A voltage drop test is a way of looking for that voltage.
Electrical System A similar ground-side test on a mower with a slowcranking starter motor can be conducted between the engine block and the negative battery post. See Figure 7.57. Figure 7.57 1. With the starter engaged, this machine exhibited a voltage-drop reading of 0.312 volts, indicating a poor ground connection. 2. Individually, these readings should lead a technician to inspect the connection between the solenoid and the ground path on the first mower (e.g.
2000 Series Tractors 6. 138 Voltage drop on a good circuit should be less than 0.1 volts. A voltage drop reading on the meter of greater than 0.2 volts indicates a fairly substantial problem that demands attention. • As an example, if the mower had a slow-turning starter, the ground-side voltage drop measured below 0.1 volts, and there was not a parasitic load on the engine (e.g. PTO clutch that is not fully disengaged), it would be logical for the technician to check voltage drop to the starter.
Electrical System Testing switches • Refer to the “COMPONENTS” section of this chapter that describes the function of the individual switches to be tested. • Switches can be tested “hot” by looking for voltage at the appropriate posts. This is not definitive, since the source of the voltage is not always confirmed. Checking for voltage does not work on switches that work by providing a ground path to the magneto primary windings or a solid state control device.
2000 Series Tractors Diodes • What is a diode? A diode acts like a one way valve, allowing current to flow in only one direction. See Figure 7.61. • Which way does this electrical check-valve work? There will be a band on one end of the diode. The band indicates the negative side of the diode • Most DMMs have the ability to test a diode. Silver band (-) (+) electrons flow from the negative to the positive. Figure 7.61 Testing a diode: 1. Isolate the diode in the circuit. 2.
Electrical System Continuity 5. There should be continuity. See Figure 7.63. 6. Switch the leads and repeat the test. 7. The meter should indicate no continuity. See Figure 7.64. 8. If the results do not match the above, replace the diode. Silver band (-) (+) Figure 7.63 No continuity Silver band (-) (+) Figure 7.
2000 Series Tractors Relay Most of the relays used by MTD or Cub Cadet have five pins. See Figure 7.65. • Windings: Terminals 1 & 2 are the outer-most of the row of three small spade terminals. When one has power and the other is connected to ground, the relay is energized. • Normally, a resistance reading between terminals 1&2 will produce a measurement of about 100Ω. This is the resistance in the windings around an iron core that energize an electromagnet or a solid-state equivalent.

Decks and Lift Systems CHAPTER 8: DECKS AND LIFT SYSTEMS Cutting decks 2000 series tractors (2011 and newer) are sold without a mowing deck. There are a variety of decks available as an attachment for the 2000 series tractor.
2000 Series Tractors 7. Carefully route the PTO belt so that it clears the deck. 8. Pull the deck support pin outward to release the deck from the lift link on both sides of the deck. See Figure 8.2. 9. Move the deck lift lever to the highest cutting position. NOTE: On tractors with an electric lift, use the lift switch to raise the lift links to their highest position. 10. Slide the cutting deck forward, while guiding the hooks on the front of the deck off of the front hanger. Figure 8.2 11.
Decks and Lift Systems Cleaning the deck Cleaning debris off of the deck should be done every time the mower is used. It is routine maintenance that will make the deck easier to work on and prolong the life of the deck and spindles. ! CAUTION Debris build up on the mower deck is an unsafe condition. The debris traps heat in the spindles causing damage to the spindle bearings. Debris around the belt can over-heat. To clean the deck while it is removed: 1.
2000 Series Tractors Blades The condition of the blades will greatly effect the quality of the cut. The blades should be sharpened and balanced after every five acres, depending on local conditions. A dull blade tears the grass instead of cutting it. Torn grass blades leaves a rough look and makes the grass vulnerable to diseases. Blades need to be examined for damage before sharpening. Blades must be balanced after sharpening to minimize vibrations. Bent blades are a sign of a blade impact.
Decks and Lift Systems 4. Bearing Protector Remove the blade. NOTE: The blade spacer and a bearing protector will come off with the blade. The bearing protector and the spacer must be installed in the same order when installing the blade. See Figure 8.6. Spacer 5. Install the blade by following the above steps in reverse order. Tighten the blade nut to a torque of 100 - 130 ft-lbs (136 - 176 Nm). NOTE: A 1 1/8” wrench can be used to hold the top of the spindle shaft. Figure 8.
2000 Series Tractors PTO belt Some cutting deck designs use a single belt to transfer power from the engine crankshaft directly to the blade spindles. Other cutting deck designs use one belt to transfer power from the engine crankshaft to a second belt that drives the blade spindles. On decks with two belts, the belt that goes around the crankshaft or PTO clutch is referred to in this text as the PTO belt. The second belt is called a deck belt.
Decks and Lift Systems ! CAUTION Cub Cadet belts are design to fit our equipment and are not standard lengths. Use of a nonOEM belt may prevent the mowing deck from working properly. To replace the PTO belt: 1. Insert a 1/2” drive breaker bar into the square hole in the deck idler bracket on the left side of the deck. See Figure 8.7. 2. Pull the breaker bar towards the rear of the mower to remove some of the belt tension. 3. Slide the belt off of the deck drive pulley. 4.
2000 Series Tractors Deck Belt NOTE: The procedure to replace the deck belt is basically the same for all five options available for the 2000 series. To replace the deck belt: 1. Remove the deck as described at the beginning of this chapter. 2. Remove the spindle covers. Single idler bracket NOTE: A 1/2” wrench can be used to remove the spindle cover screws for all five deck options available. 3. Grab the single idler bracket with a large pair of pliers. See Figure 8.9.

Remove the upper bearing protector. 3. Remove the upper bearing seal. See Figure 8.16. Bearing seal Figure 8.16 4. Remove the upper bearing. Upper bearing Figure 8.17 5. Remove the spacer. See Figure 8.18. Spacer Figure 8.
Decks and Lift Systems Lower seal 6. Remove the lower bearing seal. See Figure 8.19. 7. Remove the lower bearing. NOTE: The grease fitting in the spindle housing and the grease fitting on the spindle shaft send grease to the same spot. Only one of the fittings needs to be used when greasing a spindle. NOTE: Bearing races and cones must be kept as a matched set once they have been run. • If a bearing race or cone is to be re-used, it must be re-used with its original mate.
2000 Series Tractors Leveling the deck For the best quality cut, the deck must be level side to side and the front of the deck should be 1/4” - 3/8” lower than the rear of the deck. To level the deck: NOTE: Deck leveling is part of initial mower setup. Before adjusting an out of level deck on a mower that has been used, inspect all of the deck lift and suspension linkages. Move the deck through its full range of travel while checking linkage movement.
Decks and Lift Systems adjustment gear 4. Loosen, but do NOT remove, the hex bolt on the left deck hanger link. See Figure 8.23. 5. To level the deck, turn the adjustment gear located immediately behind the bolt. Turn the gear clockwise (rearward) to raise the left side of the deck. Turn the gear counter-clockwise (toward front) to lower the left side of the deck. See Figure 8.23. 6. The deck is properly leveled when both blade tip height measurements, as described earlier, are equal. 7.
2000 Series Tractors Deck Gauge Wheel Adjustment The cutting decks are of a “floating” design. This means that they are suspended above the ground. The gauge wheels occasionally touch the ground. They are designed to bump the deck up and over irregularities. This prevents scalping damage to the turf and to the deck. Adjust the gauge wheels as follows: 1. Place the tractor on a smooth, flat surface and move the deck to the desired mowing height.
Decks and Lift Systems Deck lift shaft bushings Split spacer The lift shaft bushings on the 2000 series tractor can be replaced without removing the lift shaft.

Maintanence Intervals CHAPTER 9: MAINTENANCE INTERVALS Lubrication To help keep the 2000 series in proper running order, Cub Cadet recommends the following lubrication intervals be used (adjustable to local conditions). Lubricate with 251H EP grease or an equivalent NGLI grade 2 lithium based multi-purpose grease.
2000 Series Tractors The spark plugs The spark plugs should be checked, cleaned and re-gapped every 200 hours of use. The plugs should be replaced when the electrode is worn out. When checking the spark plugs, a dry, light colored residue on the plugs is a sign of running lean. If there is a thick, wet, black residue on the plug the engine is running rich. There should be a dry tan coating on the plugs. This would indicate the proper mixture. To remove/replace the spark plugs: 1.
Maintanence Intervals Air filter and pre-cleaner The Kohler engines used by Cub Cadet are equipped with a foam pre-cleaner and a pleated paper air filter. A dirty air filter can reduce engine power, increase fuel consumption and make starting more difficult. The precleaner should by cleaned every 25 hours. The air filter should be cleaned every 100 hours and replaced every 200 hours of use. To clean the pre-filter: Wing nut 1. Open the hood of the tractor. See Figure 9.3. 2.
2000 Series Tractors To service the air filter: 1. Open the hood of the tractor. 2. Remove the air filter cover by loosening the cover retaining wing nut and lifting the cover off. 3. Remove and clean the foam pre-clear by following the procedures described in the previous section of this chapter. 4. Remove the element cover nut. See Figure 9.5. 5. Remove the air filter 6. The air filter can be cleaned by lightly tapping it on a hard surface.
Maintanence Intervals Oil change The oil change interval is every 100 hrs. To change the oil: Oil fill plug 1. Open the hood. 2. Clean around the fill plug. 3. Remove the oil fill plug. See Figure 9.6. 4. Place a suitable container under the oil drain at the front of the tractor. See Figure 9.7. 5. Remove the drain plug using a 7/16” wrench. 6. After all of the oil has been drained, re-install the oil drain plug. Figure 9.
2000 Series Tractors Oil filter The oil filter should be change at every other oil change or 200 hours. To replace the oil filter: 1. Drain the oil by following the steps described in the previous section of this chapter. Oil filter NOTE: If replacing a damaged filter, the filter can be removed without draining the oil. 2. Clean the area around the oil filter 3. Remove the oil filter by turning it counter-clockwise, as seen from the right side of the mower. See Figure 9.8. 4.
Maintanence Intervals Servicing the fuel system Inspect the fuel system every time the mower is operated. If dirty fuel is found in the fuel tank or fuel that does not smell “right”, drain the fuel tank and replace the fuel filter Drain the fuel tank by removing the fuel line from the fuel filter and drain the fuel into an empty safety approved gas can. Dispose of the bad fuel in a safe, responsible and legal manner. ! CAUTION Gasoline and it vapors are extremely flammable.
2000 Series Tractors 5. Clamp off the fuel lines. IMPORTANT: Take care that the fuel lines are not damaged when clamping them off. Never insert a screw or anything else into the fuel line to prevent fuel from coming out. This will damage the inside of the fuel line. NOTE: There are commercially available fuel line clamping tools that will not damage the fuel lines. 6. Squeeze the tabs on the fuel line clamps and slide them away from the filter. 7. Carefully slide the fuel lines off of the filter.
