Switching the Fuel Tanks Releasing the Parking Brake The unit has two fuel tanks, one located on the left side and one on the right side. Each tank connects to the fuel shut off valve in the control panel. From there a common fuel line leads to the engine (Fig. 12). 1. Push forward and down on the parking brake lever to release the parking brake (Fig. 13). The parking brake is disengaged. 1 To use the right side fuel tank rotate the fuel shut off valve 1/4 turn to the right from the off location.
Installing or Removing Blades 3 1. Remove blades and anti-scalp cups from spindles. Save for use when side discharging. 3 2. Install new recycler blades without anti-scalp cups. Important The sail part of the blades (i.e., the turned up section) must face the inside of the mower. 2 1 3. Tighten the blade mounting bolts to 85–110 ft.-lb. (115–150 Nm). 5 5 Installing or Removing the Baffles Important The baffles are used only for mulching. The baffles must be removed when in side discharge mode. 1.
Installing and Removing Kickers 5. Rotate the blades to ensure that there is at least 1/8 inch (3 mm) clearance between the blades and kickers. The following instructions are for removing and installing kickers. The kickers are used for mulching only. The following procedures are written as though you were to install the kickers. Reverse the procedures to remove them. Note: If a kicker interferes with a blade, reposition it further up into the mower. 6. Turn mower deck over and install belt covers.
1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to off. Remove the key. Warning A blade that is bent or damaged could break apart and could seriously injure or kill you or bystanders. 2. Remove belt covers from mower deck. 3. Remove mower unit. • Always replace a bent or damaged blade with a new blade. • Never file or create sharp notches in the edges or surfaces of the blade. 4.

Danger Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blades and thrown debris will cause injury or death. 1 m–6279 • Never remove the grass deflector from the Figure 29 mower because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately. • Never put your hands or feet under the mower.
Loading Machines 1 Use extreme caution when loading units on trailers or trucks. One full width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the unit (Fig. 30). The lower rear section of the tractor frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full width ramp provides a surface for the frame members to contact if the unit starts to tip backward.
Mow at Correct Intervals Normally, mow every four days. But remember, grass grows at different rates at different times. So to maintain the same cutting height, which is a good practice, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height; then mow again two days later at a lower height setting. Cutting Speed To improve cut quality, use a slower ground speed.
Maintenance Recommended Maintenance Schedule Maintenance Service Interval After First Use Each Use Maintenance Procedure • Check hydraulic fluid level • Change engine oil • Change hydraulic filter • • • • Check oil level Check safety system Clean cooling systems Clean mower housing Every 5 Hours • Check cutting blades • Grease blade spindle bearings Every 25 Hours • • • • • • • • Check hydraulic fluid level Grease chassis1 Oil linkage bushings1 Service foam air cleaner1 Check belts for wear/cracks C
Caution If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition and disconnect the wire from the spark plugs before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades Inspecting the Blades Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades.
Front Warning Contact with sharp blade can cause serious injury. Wear gloves or wrap sharp edges of the blade with a rag. Hold the blade end using a rag or thickly-padded glove. Remove the blade bolt, flat washer, split lock washer, and blade from the spindle shaft (Fig. 34). m–1078 Figure 32 1 2 3 4 MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 5 m–4318 m–2539 Figure 34 Figure 33 1.

Clean around the oil dipstick (Fig.
Note: Dispose of the used oil at a certified recycling center. 4. Install the replacement oil filter to the adapter. Turn the oil filter clockwise until the rubber gasket contacts the filter adapter, then tighten the filter an additional 3/4 turn (Fig. 42). 5. Fill the crankcase with the proper type of new oil; refer to Changing/Draining Oil, page 35. Servicing the Spark Plug 1 Check the spark plugs after every 100 operating hours.
Checking the Spark Plug 6. Open fuel shut-off valve on console. 1. Look at the center of the spark plugs (Fig. 44). If you see light brown or gray on the insulator, the engine is operating properly. A black coating on the insulator usually means the air cleaner is dirty. 2 Important Never clean the spark plugs. Always replace the spark plugs when it has a black coating, worn electrodes, an oily film, or cracks. 2. Check the gap between the center and side electrodes (Fig. 44).
