Safety Decals SAFETY DECALS This unit has been designed and manufactured to provide you with the safety and reliability you would expect from an industry leader in outdoor power equipment manufacturing. All DANGER, WARNING, CAUTION and instructional messages on your rider and mower should be carefully read and obeyed. Personal bodily injury can result when these instructions are not followed. The information is for your safety and it is important! The safety decals below are on your rider and mower.
Features & Controls CONTROL FUNCTIONS The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing require the combined use of several controls applied in specific sequences. To learn what combination and sequence of controls to use for various tasks see the OPERATION section. Throttle Control Ground Speed Levers The throttle controls engine speed. Move the throttle forward to increase engine speed and back to decrease engine speed.
Features & Controls Fuel Tank & Gauge Ignition Switch To remove the cap, turn counterclockwise. The fuel gauge is mounted in the fuel tank and indicates the amount of fuel in the tank. The ignition switch starts and stops the engine; it has three positions: OFF RUN Stops the engine and shuts off the electrical system. Mower Height of Cut Adjustment & Allows the engine to run and powers the electrical system.
Operation GENERAL OPERATING SAFETY CHECKS BEFORE STARTING Before first time operation: • Check that crankcase is filled to full mark on dipstick. See the engine Operator’s Manual for instructions and oil recommendations. • Make sure all nuts, bolts, screws and pins are in place and tight. • Adjust the seat position, and make certain you can reach all controls from operator’s position. • Fill the fuel tank with fresh fuel. Refer to engine manual for fuel recommendations.
Operation WARNING MOWING 1. Engage the parking brake. Make sure the PTO switch is disengaged, the motion control handles are locked in the NEUTRAL position and the operator is on the seat. 2. Start the engine (see STARTING THE ENGINE). 3. Set the mower cutting height. 4. Set the throttle to FULL. 5. Engage the PTO by pulling up on the PTO switch. 6. Begin mowing. See Section LC for tips on mowing patterns, lawn care, and trouble shooting information. 7. When finished, shut off the PTO. 8.
Operation ZERO TURN DRIVING PRACTICE Smooth Travel The lever controls of the zero turn rider are responsive . The lever controls of the zero turn rider are responsive, and learning to gain a smooth and efficient control of the rider’s forward, reverse, and turning movements will take some practice. The BEST method of handling the ground speed control levers is in three steps — as shown in Figure 3.
Operation Practice Turning Around a Corner Practice Turning In Place While traveling forward allow one handle to gradually return back toward neutral. Repeat several times. To turn in place, “zero turn,” gradually move one ground speed control lever forward from neutral and one lever back from neutral simultaneously. Repeat several times. NOTE: To prevent pivoting directly on the tire tread, it is best to keep both wheels going at least slightly forward.
Operation ATTACHING A TRAILER A The maximum weight of a towed trailer should be less than 200 lbs (91kg). Secure the trailer with an appropriately sized clevis pin (A, Figure 9) and clip (B). Excessive towed loads can cause loss of traction and loss of control on slopes. Reduce towed weight when operating on slopes. The surface being driven on greatly impacts traction and stability. Wet or slippery surfaces can greatly reduce traction and the ability to stop or turn.

Regular Maintenance MAINTENANCE SCHEDULE & PROCEDURES The following schedule should be followed for normal care of your rider and mower. You will need to keep a record of your operating time. Determining operating time is easily accomplished by observing the elapsed time recorded by the hour meter.
Regular Maintenance LUBRICATION Lubricate the unit at the following lubrication points shown in Figure 13. Oil: Grease: • control handle pivots • front caster wheel axles • discharge chute hinge • front caster yokes • mower deck idler arm Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts and pulleys. Remember to wipe fittings and surfaces clean both before and after lubrication. • mower deck arbors Use grease fittings when present.
Regular Maintenance WARNING For your personal safety, do not handle the sharp mower blades with bare hands. Careless or improper handling of blades may result in serious injury. WARNING For your personal safety, blade mounting capscrews must each be installed with a hex/spline washer and spring washer, then securely tightened. Torque blade mounting capscrew to 45 - 55 ft. lbs. (61 - 75 N.m.) LOOSEN Figure 14.
Regular Maintenance CHECK TIRE PRESSURES Tire pressure should be checked periodically, and maintained at the levels shown in the chart. Note that these pressures may differ slightly from the “Max Inflation” stamped on the side-wall of the tires. The pressures shown provide proper traction, improve cut quality, and extend tire life. CHECKING / ADDING FUEL Tire Pressure To add fuel: Front 40 psi (2,76 bar) 1. Remove the fuel cap (see A, Figure 18). 2. Fill the tank to the bottom of the filler neck.
