Read User Instructions Before Operating This Machine.
Assembly Read and follow the assembly and adjustment instructions for your mower. All fasteners are in the parts bag. Do not discard any parts or material until the unit is assembled. NOTE: In this instruction book, left and right describe the location of a part with the operator on the seat. WARNING: Before doing any assembly or maintenance to the mower, remove the wire from the spark plug. Parts Bag - Contents The fasteners and other loose parts are shown below. The fasteners are shown full size.
Installing the Seat Assembling the Steering Wheel How to Install the Seat 1. Carefully remove the plastic bag from the seat. Use the fasteners shown below to install the seat. The fasteners are shown at full size.
C D A B E F G H How to Charge the Maintenance Free Battery WARNING: When you charge the battery, do not smoke. Keep the battery away from any sparks. The fumes from the battery acid can cause an explosion. 1. Remove the battery and battery tray. 2. Remove the protective cap from the battery terminal. 3. Use a 12 volt battery charger to charge the battery. Charge at a rate of 6 amperes for one hour. If you do not have a battery charger, have an authorized service center charge the battery. 4.
1. Remove the protective cap from the battery terminal. 2. Fasten the red cable and terminal cover (if equipped) to the positive (+) terminal with the fasteners as shown (Figure 9). 3. Fasten the black cable to the negative (-) terminal with the fasteners as shown. D C E A B H Figure 9: Battery How To Check The Safety Interlock Switches To check the function of the safety interlock switches, follow the steps below. 1. Check the blade rotation control switch. Sit in the seat.
Check the Tires NOTE: The tires may be over inflated for shipment. Check the air pressure in the tires. Tires with too much air pressure will cause the unit to ride rough. Also, the wrong air pressure will keep the mower housing from cutting level. Recommended air pressure is 14 PSI (1 BAR). Check the Level of the Mower Deck Make sure the level of cut is still correct. After you mow a short distance, look at the area that was cut.
Features and Controls E F A G H I B J N ep o ro t fo du r ct io n C R D A - Throttle Control / Choke Control Levers — Throttle control increases or decreases the speed of the engine. Choke control engages the choke to start a cold engine. B - Steering Wheel (Removed for clarity) — Steers the unit. C - Brake Pedal — Quickly stops the unit. D - Deck Lift Lever — Changes the height of cut. E - PTO Switch — Starts and stops the rotation of the blades. F - Cruise Control — Locks ground speed in forward.
Operation Using Controls Attachments R N ep o ro t fo du r ct io n This unit can use many different attachments. For all pull-behind attachments or trailers, the maximum gross weight is 250 pounds. Gross weight is the weight of the attachment or trailer and any load that might be on or in it. Do not operate on a slope that is greater than 10 degrees when using a pull-behind attachment or trailer.
How to Engage the Blades The PTO switch is above and to the right of the steering wheel (Figure 10). Use the PTO switch to engage the blades. A How to Use the Speed Control Pedal The drive system uses a Hydrostatic Automatic Drive transmission. The Hydrostatic transmission is very easy to operate. This type of drive system does not require a shift lever or a clutch pedal. The speed and direction of travel is controlled by a single speed control pedal operated with your right foot.
How to Use the Cruise Control To engage the cruise control: 1. Slowly push the speed control pedal forward to the desired speed (Figure 11). 2. Pull up on the cruise control knob (Figure 12). Release the speed control pedal. The unit should continue traveling forward at the desired speed. NOTE: The cruise control only operates in forward speeds. To disengage the cruise control: 1. Push the speed control pedal (Figure 11), OR 2. Push the brake pedal.
A How to Change the Cutting Height To change the cutting height, raise or lower the deck ift lever as follows: 1. Move the deck lift lever forward to lower the mower housing and back to raise the mower deck (Figure 15). 2. When you ride on a sidewalk or road, move the deck lift lever to the highest position and disengage the blades (Figure 10).
How to Transport the Unit To transport the unit, follow the steps below. 1. Disengage the blades. 2. Raise the deck lift lever to the highest position. 3. Move the throttle control to the FAST position. 4. Slowly push the speed control pedal forward to the desired speed. Mowing N ep o ro t fo du r ct io n How to Operate the Mower Deck WARNING: The deflector is a safety device. Do not remove the deflector. The deflector forces the discharged material toward the ground.
How to Operate the Unit on Hills WARNING: Do not ride up or down slopes that are too steep to back straight up. Never ride the unit across a slope. See the “Slope Guide” in the back of this book for information on how to check slopes. 1. Control the speed only with the speed control pedal. Do not use the brake pedal on a hill. 2. To help prevent an accident, slowly move the speed control pedal. Avoid sudden turns or changes in speed. 3.
Engine Operation Before Starting the Engine Check the Oil NOTE: The engine was shipped from the factory filled with oil. Check the level of the oil. Add oil as needed. See the engine manufacturer’s instructions for the type of gasoline and oil to use. 1. Make sure the unit is level. NOTE: Do not check the level of the oil while the engine runs. 2. Check the oil. Follow the procedure in the engine manufacturer’s instructions. 3. If necessary, add oil until the oil reaches the FULL mark on the dipstick.
Tips Figure 18: Mowing tips 9. If the grass is very high, cut two times to decrease the load on the engine. First cut with the mower housing in the highest position and then lower the mower housing for the second cut. 10. For better engine performance and an even discharge of the cut grass, always operate the engine with the throttle in FAST position. 11. When you use a bagger, operate the engine with the throttle in FAST position and the speed control pedal pushed 1/3 forward. 12.
