Specifications Note: Specifications and design are subject to change without notice.
Operation Important: Do not use kerosene or gasoline instead of diesel fuel. Failure to observe this caution will damage the engine. Note: Determine the left and right sides of the machine from the normal operating position. Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness. This machine produces sound levels in excess of 85 dBA at the operators ear and can cause hearing loss through extended periods of exposure.
Note: If possible, fill the fuel tank after each use. This will minimize possible buildup of condensation inside the fuel tank. • If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a fuel dispenser nozzle. • If a fuel dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
remove an equal number of spacers from the castor forks, and adjust the rear chain (front deck only) to the desired holes. The higher heights of cut are attained by repositioning the deck caster arms to the lower set of holes on the deck mounting brackets. the remaining spacers onto the shaft. Install the tensioning cap to secure the assembly (Figure 23). Front Cutting Unit 1. Start the engine and raise the cutting units so that the height-of-cut can be changed.
6. Mount the height-of-cut chains to the desired height-of-cut hole (Figure 25) with the clevis pin and hairpin cotter. Figure 27 Note: When operating at 2-1/2 inch (64 mm) height of cut or higher, the axle bolt should be installed in the bottom castor fork hole to prevent grass buildup between the wheel and the fork. When operating at heights of cut lower than 2-1/2 inches (64 mm) and grass buildup is detected, reverse the machines direction to pull any clippings away from the wheel/fork area.
Adjusting the Skids The skids should be mounted in the lower position when operating at heights of cut greater than 2-1/2 inches (64 mm) and in the higher position when operating at heights of cut lower than 2-1/2 inches (64 mm). Note: When the skids become worn, you can switch the skid to the opposite sides of the mower, flipping them over. This will allow you to use the skids longer before replacing them. 1. Loosen the screw at the front of each skid (Figure 29). Figure 30 1. Gage wheel 2.
Checking the Mismatch Between Cutting Units compare. These numbers should be within 1/8 inch (3 mm) of each other. Make no adjustment at this time. Due to differences in grass conditions and the counterbalance setting of the traction unit, it is advised that grass be cut and appearance checked before formal cutting is started. 2. Position blade side to side on inside spindle of side cutting unit and corresponding outside spindle of front cutting unit.
