c.Locate jam nuts. (Reference control assembly in parts list).
d.Loosen jam nuts on both ends of rod con- nectors. See Control Assembly in the Illus- trated Parts Book (ONLY if mower creeps.)
e.Start unit and push throttle all the way on.
f.If unit creeps forward rotate rear rod con- nectors
Adjust the appropriate rod connector. The left rod for the left side of the mower and the right rod for the right side of mower. Afterward, retighten jam nuts.
E. Brakes
While the mower is in motion, all braking is performed dynamically through the hydraulic pumps and traction motors, controlled by the two steering levers. When the mower is parked with the engine shut off, the hydraulic system locks the traction wheels.
Note: To move the mower forward or in reverse by pushing, you must release the dynamic braking. Locate the valves on the pump. Turn valves
Hydro Release Valve
When the mower is parked with the engine running and the steering levers opened out in the neutral position, the parking brakes should be applied. The parking brakes are
1.Adjustments: The parking brake handle is an overcenter lever that should engage with moderate force.
Note: To increase parking brake capacity tighten the brake rods going back to the brake arms equally. Tighten rods one full turn and check parking capacity. Repeat Step.
To adjust either brake individually, tighten the hex nut in a clockwise direction one full turn looking down the brake rod. This will tighten the brake about .040 inch. Normally, both brakes should be adjusted and equal amount.
2.Repair: The mower is equipped with drum brakes and will not normally require mainte- nance. If they are not working properly, please contact your service center.
F.Hydraulic System
1.Hoses: Check the hoses from the hydraulic oil tank to the oil filter to the hydraulic lines daily for leaks or abrasion and replace any damaged hoses. Make certain there are no kinks or twists in any hose.
2.Hydraulic Oil Tank and Filter:
Note: Change the hydraulic oil and the oil
filter after the first 500 hours of operation and every 500 hours thereafter.
To drain the hydraulic oil tank, place a 2 gallon drain pan under the drain plug on the bottom of the hydraulic oil tank. Remove the drain plug, drain the tank, then replace the plug. Place the drain pan under the filter and remove the filter by unscrewing in a counterclockwise direction. The filter will be full of oil, so empty it into the drain pan. You don’t have to drain the rest of the hydraulic system. Fill the replacement filter with a good grade of 5W40 Synthetic oil and lubricate the sealing surface. Screw the filter onto the filter base until it seats and then another
Note: Always wipe off the hydraulic tank fill
cap and the area around it before removing the cap to prevent dirt from contaminating the oil.
Remove the fill cap and fill the tank with the same 5W40 Synthetic oil selected for the filter until the oil level is up to the level of the second hole in the fill tube. Leave this air space for expansion. Start the engine and let it run at idle for about five minutes. Check the filter for leaks. Idling the engine and the pumps in this way will purge any air from the system. Shut off the engine and recheck the oil level in the tank.
Note: After unit is up to operating tempera-
ture, turn off engine and
