Hour Meter 4. Check Tire Pressure Records total number of hours the engine has been run. See Specifications on page 29 for correct tire pressure. 5. Check Hydraulic Fluid Level IMPORTANT: Keep a record of Hour Meter readings for recommended Lubrication and Maintenance intervals. NOTE: For accurate readings be sure Ignition Switch is OFF when unit is not in operation. FILLING FUEL TANK See Check Hydraulic Fluid Level on page 17. 6.
TO MOW WITH UNIT 6. Engage parking brake. 7. Push the right and left bypass levers to the drive position. Operate the unit only when seated in the operator’s position. 1. Start the engine. Let the engine warm until it is running smoothly. 2. Release parking brake.

FOR BEST PERFORMANCE Mow with the engine set at full throttle. When mulching, only remove 1/3 of grass length per cutting. Do not cut more than 1 inch (2.54 cm) at any one time. Discharge clippings into areas already cut. Vary cutting pattern with each mowing. Do not allow grass or debris to collect inside of mower deck. Clean after each use. Cut grass when it is dry. Keep mower blades sharp. Keep mower deck properly levelled. Adjust anti-scalp rollers to prevent scalping.
Period Service Task Each Use Follow Engine Manual Maintenance Schedule Perform scheduled engine maintenance. Refer to engine manual for detailed instructions.

Check Hydraulic Fluid Level 2 1 Check the system with the unit cold and parked on a flat, level surface. Then run the unit for about one minute and recheck the levels. 2 To Add Hydraulic Fluid: 3 1. Remove the cap from the expansion tank. 2. Fill the expansion tank with 20W-50 engine oil with an SL API classification until oil level reaches the cold fill line on the tank. 3. Install the expansion tank cap and then purge the system. See Purging the Hydraulic System on page 18. OF4310 4 1.
6. Install the filter guards removed in step 2. Tighten the mounting screws to 65 lbf-in (7.3 N•m). 7. Fill with 20W-50 engine oil with an SL API classification until oil appears at the bottom of the drain plug (about 2 quarts per transaxle). Install the drain plug and tighten it to 180 lbf-in (20.3 N•m). 8. Repeat steps 1–7 for the other transaxle. 9. Follow the instructions in To Add Hydraulic Fluid: on page 17. 2 1 4. Stop the engine and put the transaxle bypass levers in the drive position.
4. Install mower blade(s) on unit. 5. Tighten the bolts to a torque of 115-125 lbf-ft (156-169.5 N•m). DO NOT Sharpen to This Pattern 2 1 1 2 3 DISCARD if More Than 1/2 in. (1.27 cm) 4 1 1. Blade 2.

ADJUSTING THE PARKING BRAKE PTO BELT The parking brake should not need adjustment, however if the parking brake does not hold the unit properly, the brake may need adjustment. WARNING: MOVING PARTS can cut or amputate body parts. ALWAYS wait for moving parts to stop before performing maintenance or service. Check Adjustment NOTE: Be sure to check the parking brake on both sides of the unit (Figure 17). 1. Engage parking brake and set both transmission bypass valves to the neutral position.
1. Slowly release the tension on the long mower belt idler until all the tension is removed from the springs. 2. Remove long mower belt from left blade spindle and remove from deck. 3. Slowly release the tension on the short belt idler until all the tension is removed from the springs. 4. Remove short mower belt from right blade spindle and from deck. Idler pivot bolt must be loosened slightly to gain clearance to remove belt from under idler pulley (Figure 19). 5.
MOWER DECKS Push the mower lift pedal forward between cutting height number 4 and number 5 to align the holes in the deck lift shaft and the deck lift cover. Insert the cutting height pin in the holes on the side of the deck lift cover so it passes all the way through the deck lift cover and shaft. Anti-scalp Roller Adjustment The anti-scalp rollers are set at the factory for typical mowing height, but can be adjusted for high or low cutting conditions (Figure 21).
Installing the Mower Deck (Figure 22) 1. Slide mower deck under unit. 2. Connect mower mounting arms to deck with mower mounting pins. 3. Install link chains on the mower lift arms in the same holes they were removed from. 4. Install PTO mower belt (See Replacing Mower Belts on page 23). 5. Level mower deck (See Leveling the Mower Deck on page 26). NOTE: Pitching the front of the blades lower than the rear provides a balance between cut quality and the power needed to cut grass.
Fuel System Height Adjusters Gasoline left in the fuel system for extended periods without a stabilizer will deteriorate, resulting in gum deposits in the system. These deposits can damage the carburetor and the fuel hoses, filter and tank. Prevent deposits from forming in the fuel system during storage by adding a quality fuel stabilizer to the fuel. Follow the recommended mix ratio found on the fuel stabilizer container. To treat the fuel system for storage: 1.
