Note:
If you wish to move the mower by
pushing, you must release the dynamic brak-
ing. Locate the levers at the rear of the mower.
Pull both levers out and lock in position. After
pushing the mower to the desired location,
return both levers to the operating position
(See photo at right).
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
drum-type brakes mounted on each traction
wheel.They are both engaged by the same
operating lever.
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, disconnect the brake rod from the brake
arm by removing the cotter pin from the clevis pin and pulling the clevis pin
from the brake clevis. Loosen the hex nut and turn the brake clevis in a
clockwise direction one full turn looking down the brake rod. This will
tighten the brake about .040 inch. Tighten the hex nut and reassemble the
brake clevis to the brake shaft assembly. Normally, both brakes should be
adjusted and equal amount.
2. Repair: The mower is equipped with internal wet drum brakes and
will not normally require maintenance. If they are not working prop-
erly, 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 50 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
