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.
Safety Icons & Interlock System SAFETY INTERLOCK SYSTEM This unit is equipped with safety interlock switches. These safety systems are present for your safety, do not attempt to bypass safety switches, and never tamper with safety devices. Check their operation regularly. Operational SAFETY Checks Test 1 — Engine should NOT crank if: • PTO switch is engaged, OR • Parking brake is not engaged, OR • Motion control handles are not in the NEUTRAL position.
Features & Controls Figure 1. Control Locations 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. Choke Deck Lift Pedal, Cutting Height Adjustment Pin & Deck Lift Lock Lever Close the choke for cold starting.
Features & Controls Ignition Switch Fuel Tank Cap The ignition switch starts and stops the engine, it has three positions: To remove the cap, turn counterclockwise. OFF Stops the engine and shuts off the electrical system. RUN Allows the engine to run and powers the electrical system. START Cranks the engine for starting. NOTE: Never leave the ignition switch in the RUN position with the engine stopped–this drains the battery. Fuel Level Gauge Displays the fuel level in the tank.
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 levers 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 bring one handle gradually 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 RAISE & LOWER THE ROLL BAR C To lower the roll bar: 1. Pull the hair pin clips (A, Figure 9) out of the retainer pins (B). 2. Push or pull the top of the roll bar (C) forward against the rubber stops (D) and remove the retainer pins (B). 3. Lower the roll bar and reinstall the retainer pins and hair pin clips to secure the roll bar in the down position (see insert, Figure 10). D C To raise the roll bar: A 1. Pull the hair pin clips (A) out of the retainer pins (B) and remove the retainer pins.
Operation ATTACHING A TRAILER A The maximum weight of a towed trailer should be less than 200 lbs (91kg). Secure the trailer with a appropriately sized clevis pin (A, Figure 10) 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 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 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. Tire Pressure Front 25 psi (1,72 bar) Rear 15 psi (1,03 bar) Figure 11.
Regular Maintenance LUBRICATION Lubricate the unit at the locations shown in Figures 13 through 16 as well as the following lubrication points. Grease: • • • • front caster wheel axles & yokes deck lift pivot blocks mower deck spindles mower deck idler arm Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed. Figure 13. Deck Lubrication Not all greases are compatible.
Regular Maintenance CHECK HYDRAULIC OIL LEVEL 1. Before removing the reservoir cap, make sure the area around the reservoir cap and fill neck of the reservoir is free of dust, dirt, or other debris. 2. Unscrew the reservoir cap (B, Figure 17). 3. Look down the filler neck of the hydraulic oil reservoir (A, Figure 17) and observe the oil level. When cold, the oil level should be approximately 4” (10 cm) below top of the filler neck. 4.
Regular Maintenance SERVICING THE MOWER BLADES 1. Blades should be sharp and free of nicks and dents. If not, sharpen blades as described in the following steps. 2. To remove blade for sharpening, use a 1” wrench on the flats of the spindle shaft while removing the blade mounting bolt with a 15/16” wrench (Figure 19). 3. Use a file to sharpen blade to fine edge. Remove all nicks and dents in blade edge. If blade is severely damaged, it should be replaced. 4. Balance the blade as shown in Figure 20.
Troubleshooting Adjustments & Service TROUBLESHOOTING WARNING While normal care and regular maintenance will extend the life of your equipment, prolonged or constant use may eventually require that service be performed to allow it to continue operating properly.
