Activating the Battery Warning Bulk electrolyte with 1.265 specific gravity must be purchased from a local battery supply outlet. Charging battery produces gasses that can explode and cause serious injury. Danger • Keep cigarettes, sparks and flames away from battery. • Make sure the ignition switch is off. • Ventilate when charging or using battery in an enclosed space. Battery electrolyte contains sulfuric acid which is a deadly poison and causes severe burns.
Grease the fittings on the three spindle bearings. Grease until it comes out of the lower seals (Fig. 7). 1 Figure 8 1. Warning—wear hearing protection. Controls Become familiar with all the controls (Fig. 9) before you start the engine and operate the machine. M–5036 Figure 7 2 1. Spindles Checking the Hydraulic Fluid 6 8 3 11 1 7 Check the hydraulic fluid level before the engine is first started; refer to Checking the Hydraulic Fluid, page 37.
Hour Meter Warning The hour meter records the number of hours the engine has operated. It operates when the engine is running. Use these times for scheduling regular maintenance. Parking brake may not hold machine parked on a slope and could cause personal injury or property damage. 1 Do not park on slopes unless wheels are chocked or blocked Releasing the Parking Brake m–3077 Figure 10 Push forward and down on the parking brake lever to release the parking brake (Fig. 12).
5. Pull wire off spark plug(s) to prevent possibility of someone accidentally starting the machine before transporting or storing machine. 6. Turn the ignition key to Start to energize the starter. When the engines starts, release the key (Fig. 16). Important Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, allow a 30 second cool-down period between attempts. Failure to follow these instructions can burn out the starter motor. 6.
Disengaging the PTO 3. Sitting on the seat, engage the parking brake, move the PTO to Off, and lock the motion control levers in neutral. Now start the engine. While the engine is running, release the parking brake, engage the PTO, and rise slightly from the seat; the engine should stop. 1. To disengage, push the PTO switch to the Off position (Fig. 17). The Safety Interlock System 4. Sitting on the seat, engage the parking brake, move the PTO to Off, and lock the motion control levers in to neutral.
Adjusting the Height-of-Cut To stop, pull the motion control levers to neutral. The height-of-cut is adjusted from 1-1/2 to 5 inch (38 to 127 mm) in 1/4 inch (6 mm) increments by relocating the clevis pin in different hole locations. 2 3 1. Raise the height-of-cut lever to the transport position (also the 5 inch [127 mm] cutting height position) (Fig. 19). 1 4 2.

the unit starts to tip backward. If it is not possible to use one full width ramp, use enough individual ramps to simulate a full width continuous ramp. 1 The ramp should be long enough so that the angles between the ramp and the ground and the ramp and the trailer or truck do not exceed 15 degrees. A steeper angle may cause mower deck components to get caught as the unit moves from ramp to trailer or truck. Steeper angles may also cause the unit to tip backward.
Warning Warning Unit could fall onto someone and cause serious injury or death. Parking brake may not hold machine parked on Z Stand and could cause personal injury or property damage. • Use extreme caution when operating unit on Z Stand. • Use only for cleaning deck and removing blades. • Do not keep unit on Z Stand for extended periods of time. • Always shut engine off and set parking brake before performing any maintenance to deck. Do not park on Z Stand unless wheels are chocked or blocked. 8.
Using the Lift Assist Lever Mow at Correct Intervals The lift assist lever is used along with the height-of-cut lever for raising the deck. This allows for easier raising of the deck. Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position.
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
3 5 4 MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 2 1 m–2539 3 Figure 29 4 M–4226 2. Rotate the opposite ends of the blades forward. Figure 30 3. Measure from a level surface to the cutting edge of the blades at the same position as in step 1 above. The difference between the dimensions obtained in steps 1 and 2 must not exceed 1/8 inch (3 mm). If this dimension exceeds 1/8 inch (3 mm), the blade is bent and must be replaced; refer to Removing the Blades and Installing the Blades, page 30. 1.
Installing the Blades Cleaning the Paper Elements 1. Install the blade onto the spindle shaft (Fig. 30). 1. Lightly tap the element on a flat surface to remove dust and dirt (Fig. 34). Important The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. 2. Inspect the element for tears, an oily film, and damage to the rubber seal. Important Never clean the paper element with pressurized air or liquids, such as solvent, gas, or kerosene.
Changing the Oil Viscosity: See the table below. USE THESE SAE VISCOSITY OILS Replace the oil every 100 hours. 1. Start the engine and let it run for five minutes. This warms the oil so that it drains better. 2. Park the machine so that the drain side is slightly lower than the opposite side to ensure that the oil drains completely. Disengage the power take off (PTO), set the parking brake, stop the engine, and remove the key. 3. Place a pan below the oil drain.
4. Apply a thin coat of new oil to the rubber gasket on the replacement filter (Fig. 37). Danger Rotating shaft and fan can cause personal injury. • Do not operate the machine without the covers in place. • Keep fingers, hands and clothing clear of rotating fan and drive shaft. • Shut off the engine and remove the ignition key before performing maintenance. 3 1 2 Caution m–1256 Swallowing engine coolant can cause poisoning.
