Throttle Control Hour Meter (Model 74787 Only) The throttle control is variable between the FAST and SLOW positions. Moving throttle lever forward increases the engine speed and moving it rearward decreases the engine speed (Figure 5). The hour meter records the number of hours when the operator is in the seat and the ignition switch is in the ON position (Figure 7). 1 Blade-Control Switch (Power Takeoff) The blade-control switch (PTO) engages and disengages power to the mower blades (Figure 5).
Operation DANGER In certain conditions during fueling, static electricity can be released, causing a spark that can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling.
Think Safety First of varnish deposits in the fuel system, use fuel stabilizer at all times. Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets, or bystanders avoid injury. Filling the Fuel Tank Note: Ensure that the engine is shut off. DANGER Note: You can use the fuel window to verify the presence of gasoline before filling the tank (Figure 8).
1 6. Ensure that the traction pedal is in neutral and turn the ignition switch to the START position. The PTO should disengage and the engine should crank and start without the blades moving. 2 7. With the engine running, rise from the seat. The engine should remain running and the brake light will be on. G009027 Figure 10 1. Wear eye protection. 8. Return to the seat and disengage the parking brake by pushing the SmartPark switch to the OFF position. The engine should continue to run. 2.
Starting the Engine Operating the Blades Important: Do not engage the starter for more than 5 seconds at a time. Engaging the starter motor for more than 5 seconds can damage the starter motor. If the engine fails to start, wait 10 seconds before operating the engine starter again. The blade-control switch engages and disengages power to the mower blades. This switch controls power to any attachments that draw power from the engine, including the mower deck and cutting blades.
Driving the Machine Stopping the Machine This machine has the characteristics of both a garden tractor and a zero-turn machine. Like a garden tractor, the machine has a foot pedal that controls the forward and reverse motion along with the speed, and it has a steering wheel that controls the direction and the turning radius. Like a zero-turn machine, the rear drive wheels operate independently of each other, enabling you to make sharp turns and to turn in different directions quickly.
4. Perform the mowing. Positioning the Seat 5. When finished mowing, remove the KeyChoice key (Figure 6). The seat can move forward and backward. Position the seat where you have the best control of the machine and are most comfortable. Note: Once you deactivate the interlock, it stays in this mode—with your mower blade or PTO powered attachment operating whenever you back up—and the console light stays on until you either disengage the PTO or turn off the engine.
Adjusting the Anti-scalp Rollers Adjusting the Anti-scalp Rollers 42-inch Mower Decks Only 54-inch Mower Decks Only Whenever you change the height of cut, adjust the height of the anti-scalp rollers. Whenever you change the height of cut, adjust the height of the anti-scalp rollers. Note: Adjust the anti-scalp rollers so the rollers do not touch the ground in normal, flat mowing areas. Note: Adjust the anti-scalp rollers so the rollers do not touch the ground in normal, flat mowing areas. 1.
Using the Grass Deflector 5. Turn the ignition key to the ON position and disengage the parking brake. The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. Note: Do not start the machine. 3 DANGER Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris causes injury or death.
WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use extreme caution when operating a machine on a ramp. • Use only a full-width ramp; do not use individual ramps for each side of the machine. Figure 21 • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.
Operating Tips 1 Using the Fast Throttle Setting For best mowing and maximum air circulation, operate the engine at the FAST position. Air is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower in uncut grass. Always try to have 1 side of the mower free from uncut grass, which allows air to be drawn into the mower.
Stopping If you must stop the forward motion of the machine while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or you can disengage the mower deck while moving forward. Keeping the Underside of the Mower Clean Clean clippings and dirt from the underside of the mower after each use. If grass and dirt build up inside the mower, cutting quality will eventually become unsatisfactory.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 5 hours • Change the engine oil. Before each use or daily • • • • • Check the engine-oil level. Clean the air intake screen. Check the cutting blades. Inspect the grass deflector for damage. Inspect the grass deflector for damage. After each use • Check and clean the front of the mower.
Premaintenance Procedures Lubrication Raising the Seat Service Interval: Every 25 hours—Grease all the lubrication points. Greasing the Bearings Engage the parking brake and lift the seat forward. Grease Type: No. 2 lithium grease You can access the following components by raising the seat: 1. Park the machine on a level surface, and disengage the blade-control switch. • Serial plate • Service decal 2.

Slowly pour approximately 80% of the specified oil into the filler tube and slowly add the additional oil to bring it to the Full mark (Figure 33).
A Note: Due to the deep recess around the spark plug, blowing out the cavity with compressed air is usually the most effective method for cleaning. The spark plug is most accessible when the blower housing is removed for cleaning. B Checking the Spark Plug C E D Important: Do not clean the spark plug(s). Always replace the spark plug(s) when it has: a black coating, worn electrodes, an oily film, or cracks. If you see light brown or gray on the insulator, the engine is operating properly.
Cleaning the Cooling System Fuel System Maintenance Clean the air intake screen from grass and debris before each use. 1. Disengage the blade-control switch and engage the parking brake. DANGER In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. 2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3.
Replacing the In-Line Fuel Filter Electrical System Maintenance Service Interval: Every 100 hours/Yearly (whichever comes first)—Check the in-line fuel filter. WARNING Every 200 hours/Every 2 years (whichever comes first)—Replace the in-line fuel filter. CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm.

Servicing the Fuses Drive System Maintenance The electrical system is protected by fuses. It requires no maintenance; however, if a fuse blows, check the component or circuit for a malfunction or short. Fuse type: Checking the Tire Pressure • Main—F1-30 A, blade-type Service Interval: Every 25 hours—Check the tire pressure. • Charge Circuit—F2-25 A, blade-type Maintain the air pressure in the front and rear tires as specified. Uneven tire pressure can cause uneven cut.
Releasing the Electric Brake Mower Maintenance The electric brake can be release by manually rotating the link arms forward. Once the electric brake is energized, the brake will reset. Servicing the Cutting Blades Maintain sharp and balanced blades throughout the cutting season, because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth, and increases the chance of disease.
