some components.
1.
Position the machine on a level surface, lower the cutting units,
stop the engine, engage the parking brakes and remove the key
from the ignition switch.
2.
Clean the area around the filter mounting area. Place the drain
pan under the filter and remove the filter.
3.
Lubricate the new filter gasket and fill the filter with hydraulic
fluid.
4.
Assure the filter mounting area is clean. Screw the filter on
until gasket contacts mounting plate. Then tighten the filter
one-half turn.
5.
Start the engine and let it run for about two minutes to purge
air from the system. Stop the engine and check for leaks.
CHECKING HYDRAULIC LINES AND
HOSES
Inspect hydraulic lines and hoses daily for leaks, kinked lines, loose
mounting supports, wear, loose fittings, weather deterioration and
chemical deterioration. Make all necessary repairs before operating.
ADJUSTING THE TRACTION DRIVE FOR
NEUTRAL (Fig. 44)
The machine must not creep when the traction pedal is released. If
it does creep, an adjustment is required.
1.
Park the machine on a level surface, shut the engine off and
lower cutting units to the floor. Depress only the right brake
pedal and engage the parking brake.
2.
Jack up the left side of the machine until front tire is off the
shop floor. Support the machine with the jack stands to prevent
it from falling accidentally.
Note: On 4-wheel drive models, the left rear tire must also be
off the shop floor.
3.
Start the engine and allow it to run at low idle.
4.
Adjust the jam nuts on the pump rod end to move the pump
control tube forward to eliminate forward creep or rearward to
eliminate rearward creep.
