OPERATION The operation of any tractor can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your tractor or performing any adjustments or repairs. We recommend a wide vision safety mask over spectacles or standard safety glasses. HOW TO USE YOUR TRACTOR TO SET PARKING BRAKE (See Fig. 6) Your tractor is equipped with an operator presence sensing switch. When engine is running, any attempt by the operator to leave the seat without first setting the parking brake will shut off the engine. • Depress clutch/brake pedal into full "BRAKE" position and hold. • Place parking brake lever in "ENGAGED" position and release pressure from clutch/brake pedal. Pedal should remain in "BRAKE" position. Make sure parking brake will hold tractor secure. • Never use choke to stop engine. IMPORTANT: LEAVING THE IGNITION SWITCH IN ANY POSITION OTHER THAN "OFF" WILL CAUSE THE BATTERY TO BE DISCHARGED, (DEAD). NOTE: Under certain conditions when tractor is standing idle with the engine running, hot engine exhaust gases may cause "browning" of grass. To eliminate this possibility, always stop engine when stopping tractor on grass areas. CAUTION: Always stop tractor completely, as described above, before leaving the operator's position; to empty grass catcher, etc. CHOKE CONTROL LEVER THROTTLE CONTROL LEVER "BRAKE" POSITION ATTACHMENT CLUTCH LEVER "ENGAGED" POSITION IGNITION KEY "DISENGAGED" POSITION PARKING BRAKE "ENGAGED" POSITION TO USE THROTTLE CONTROL (SEE FIG. 6) Always operate engine at full throttle. • Operating engine at less than full throttle reduces the battery charging rate. • Full throttle offers the best bagging and mower perfor- mance. TO USE CHOKE CONTROL (See Fig. 6) Use choke control whenever you are starting a cold engine. Do not use to start a warm engine. • To engage choke control, pull knob out. Slowly push knob in to disengage. CLUTCH/BRAKE PEDAL "DRIVE" POSITION MOTION CONTROL LEVER PARKING BRAKE "DISENGAGED" POSITION FIG. 6 STOPPING (See Fig. 6) TO MOVE FORWARD AND BACKWARD (See Fig. 6) The direction and speed of movement is controlled by the motion control lever. • Start tractor with motion control lever in neutral (N) position. • Release parking brake and clutch/brake pedal. • Slowly move motion control lever to desired position. MOWER BLADES • To stop mower blades,move attachment clutch lever to "DISENGAGED" position. GROUND DRIVE • To stop ground drive, depress clutch/brake pedal into full "BRAKE" position. • Move motion control lever to neutral (N) position. TO ADJUST MOWER CUTTING HEIGHT (See Fig. 6) The position of the attachment lift lever determines the cutting height. • Grasp lift lever. • Press plunger with thumb and move lever to desired position. IMPORTANT: THE MOTION CONTROL LEVER DOES NOT RETURN TO NEUTRAL (N) POSITION WHEN THE CLUTCH/BRAKE PEDAL IS DEPRESSED. ENGINE • Move throttle control to slow position. The cutting height range is approximately 1-1/2 to 4". The heights are measured from the ground to the blade tip with the engine not running. These heights are approximate and may vary depending upon soil conditions, height of grass and types of grass being mowed. NOTE: Failure to move throttle control to slow position and • allowing engine to idle before stopping may cause engine to "backfire". • Turn ignition key to "OFF" position and remove key. Always remove key when leaving tractor to prevent unauthorized use. 11 The average lawn should be cut to approximately 2-1/2 inches during the cool season and to over 3 inches during hot months. For healthier and better looking lawns, mow often and after moderate growth.
