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 Ignition Switch The ignition switch starts and stops the engine; it has three positions: OFF Stops the engine and shuts off the electrical system. RUN Allows the engine to run and powers the electrical system. Fuel Level Gauge To remove the cap, turn counterclockwise. The fuel gauge is mounted in the fuel tank and indicates the amount of fuel in the tank. Mower Height of Cut Adjustment & START Cranks the engine for starting.
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.

Lawn Care & Mowing Information HOW AND WHEN TO WATER, FERTILIZE & AERATE HOW TO WATER YOUR LAWN Most lawns are watered too often, but with too little water. However too much water can allow development of diseases with your lawn. It is best to water the lawn only when necessary, and then to water it slowly, evenly, and deeply—imitating a slow, soaking rain. HOW TO FERTILIZE YOUR LAWN The best method of watering a lawn is to imitate a slow, soaking rain, applying about 1 inch of water.
Lawn Care & Mowing Information WHEN AND HOW OFTEN TO MOW The time of day and condition of the grass greatly affect the results you’ll get when mowing. For the best results, follow these guidelines: ● Mow when the grass is between 3”-4” (7,5-10 cm) high. ● Mow with sharp blades. Short clippings of grass one inch or shorter decompose more quickly than longer blades. Sharp mower blades cut grass cleanly and efficiently, preventing frayed edges which harm the grass.
