Product Overview Figure 12 1. Steering wheel 2. Traction pedal 3. 4. Brakes Cutting unit 5. Hood/engine compartment 6. ROPS (Rollover Protection System) Controls Service Brakes The left and right brake pedals (Figure 13) are connected to the left and right front wheels. Since both brakes work independently of each other, the brakes can be used to turn sharply or to increase traction if one wheel tends to slip while operating on certain slope conditions.
Traction Pedal The traction pedal (Figure 15) has two functions: one is to make the machine move forward, the other is to make it move rearward. Using the heel and toe of the right foot, press the top of the pedal to move forward and the bottom of the pedal to move rearward. Ground speed is proportionate to how far the pedal is pressed. For maximum ground speed, the traction pedal must be fully depressed while throttle is in the Fast position. Maximum speed forward is 10 mph (approx.).

Oil Pressure Warning Light The oil pressure warning light (Figure 17) glows when the oil pressure in engine drops below a safe level. If low oil pressure ever occurs, stop the engine and determine the cause. Repair the damage before starting the engine again. Lift Lever Lock Lock the lift lever (Figure 17), in the raised position, when performing maintenance on the deck. Figure 18 1.
Operation This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Adequate rear weight is necessary to prevent the rear wheels from leaving the ground. Do not stop suddenly while deck or implement is raised. Do not travel down hill with the deck or implement raised. If the rear wheel leaves the ground, steering is lost. Figure 19 1. Dipstick 3.

Check the level of the coolant in the expansion tank (Figure 21).
Adding Fuel Checking the Rear Axle Lubricant (Model 30309 only) Fuel tank capacity is approximately 12.8 gallon (48 l). The rear axle has three separate reservoirs which use SAE 80W-90 wt. gear lube. Although the axle is shipped with lubricant from the factory, check the level before operating the machine. Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage. 1.
2. Rotate the clutch (Figure 26) so that the check plug (shown in the 12 o’clock position) is positioned at 4 o’clock. There is no rollover protection when the roll bar is in the down position. • Lower the roll bar only when absolutely necessary. • Do not wear the seat belt when the roll bar is in the down position. • Drive slowly and carefully. • Raise the roll bar as soon as clearance permits. • Check carefully for overhead clearances (i.e.
Important: When engine is started for the first time, or after an engine oil change, or overhaul of the engine, transmission, or axle, operate the machine in forward and reverse for one to two minutes. Also operate the lift lever and PTO lever to ensure proper operation of all parts. Turn the power steering wheel to the left and right to check the steering response. Then shut the engine off and check fluid levels, check for oil leaks, loose parts, and any other noticeable malfunctions. 4.
3. Open the air bleed screw on the fuel injection pump (Figure 28). If the safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury. • Do not tamper with the interlock switches. • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine. Figure 28 • Replace switches every two years regardless of whether they are operating properly or not. 1. Fuel injection pump bleed screw 4.
Important: Do not push or tow the machine faster than 2 to 3 mph because the transmission may be damaged. If the machine must be moved a considerable distance, transport it on a truck or trailer. Whenever the machine is pushed or towed, the by-pass valve must be open. 1. Loosen the knob and remove the access cover at the rear of the seat mounting plate (Figure 29). Important: Running the machine with the by-pass valve open will cause the transmission to overheat. 4. Install the access cover.

Figure 32 Service Interval Chart Lubrication Greasing the Bearings and Bushings The machine has grease fittings that must be lubricated regularly with No. 2 General Purpose Lithium Base Grease. If machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation. Bearings and bushings must be lubricated daily when operating conditions are extremely dusty and dirty.

The most common reason for failure is moisture and contamination working its way past the protective seals. Bearings that are greased will rely upon regular maintenance to purge harmful debris from the bearing area.
under normal use, but periodic inspections of bearing condition and seal integrity should be conducted to avoid downtime. These bearings should be inspected seasonally and replaced if damaged or worn. Bearings should operate smoothly with no detrimental characteristics such as high heat, noise, looseness or indications of corrosion (rust). Due to the operating conditions these bearing/seal packages are subject to (i.e. sand, turf chemicals, water, impacts, etc.) they are considered normal wear items.
Changing the Engine Oil And Filter Important: Avoid using high pressure air which could force dirt through the filter into the intake tract. Check oil level after each day’s operation or each time machine is used. Change oil and filter initially after first 50 hours of operation; change oil and filter after every 150 hours of operation thereafter. If possible, run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil. 4.
Fuel System Maintenance Replacing Fuel Pre Filter Replace the fuel pre filter (Figure 49), located between fuel tank and fuel pump after every 450 operating hours or yearly, whichever occurs first. Note: Refer to Filling the Fuel Tank for proper fuel recommendations. 1. Clamp both fuel lines that connect to the fuel filter so fuel cannot drain when the lines are removed (Figure 49). Draining the Water Separator Drain water or other contaminants from water separator (Figure 48) daily.
Electrical System Maintenance Important: Ensure that the arrow on the side of the filter points toward the injection pump. Servicing the Battery Fuel Lines and Connections Warning Check the fuel lines and connections every 400 hours or yearly, whichever comes first. Inspect them for deterioration, damage, or loose connections.
Important: Whenever working with the electrical system, always disconnect the battery cables, negative (-) cable first, to prevent possible wiring damage from short-outs. the clamps and terminals separately. Reconnect the cables, positive (+) cable first, and coat the terminals with petroleum jelly. Battery terminals or metal tools could short against metal machine components causing sparks. Sparks can cause the battery gasses to explode, resulting in personal injury.
5. Rotate the clutch so that the check plug is positioned at 4 O’clock. 6. Add Mobil Fluid 424 until the lubricant level is up to the hole in the clutch. The clutch should be approximately 1/3 full. 7. Install the check plug. Note: Do not use engine oil (i.e. 10W30) in the bidirectional clutch. Anti-wear and extreme pressure additives will cause undesirable clutch performance. Figure 52 1. Drain plugs (3) 2. Tie rod Adjusting the Traction Drive for Neutral 3.
Adjusting Rear Wheel Toe-in (Model 30309 only) The rear wheels should not toe-in or toe-out when they are adjusted correctly. To check the rear wheel toe-in, measure the center-to-center distance at wheel hub height, in front and in back of the rear tires. If the wheels toe-in or toe-out, an adjustment is required. 1. Rotate the steering wheel so rear wheels are straight ahead. 2.
radiator frequently in extremely dusty and dirty conditions. 5. Align the parking brake rod paddle with the switch plunger (Figure 57) Note: If engine shuts off due to overheating, first check the radiator and screen for excessive buildup of debris. Clean the radiator as follows: 1. Remove the screen. 2. Working from the fan side of the radiator, blow with low pressure (25 psi) compressed air (do not use water). Repeat the step from the front of the radiator and again from the fan side. 3.
Free travel is the distance the brake pedal moves before braking resistance is felt. 1. Proper tension will allow 3/8 inch (10 mm) deflection when a force of 10 lb is applied on the belt, midway between the pulleys. The brakes should be checked for adjustment after the first 10 hours of operation and should only need adjusting after considerable use thereafter. These periodic adjustments can be performed where the brake cable connects to the bottom of the brake pedals.
