Initially, replace the hydraulic system oil and filter after
the first full day's operation Ċ NOT TO EXCEED 10
HOURS. Replace the oil and filter every 250 hours
thereafter. The hydraulic system is designed to operate
on any high quality detergent oil having the American
Petroleum Institute Ċ API Ċ service classification"
SF/CC or CD. Oil viscosity Ċ weight Ċ must be
selected according to anticipated ambient
temperature for the season in which product will be
used.

-1& Do not mix engine oil and automatic
transmission fluid or hydraulic component damage
may result. When changing fluids, also change
transmission filter.
-1& Fluid to operate the power steering is supplied
by the hydraulic system transmission charge pump.
Cold weather start-up may result in stiff" operation of
the steering until the hydraulic system has warmed up.
Using proper weight hydraulic oil in system will
minimize this condition.
The axle housing acts as the reservoir for the system.
The transmission and axle housing are shipped from
the factory with approximately 5 quarts (4.7 l) of SAE
10WĆ30 engine oil. However, check level of
transmission oil before engine is first started and daily
thereafter.
Lower cutting unit to shop floor, set parking brake,
and turn engine OFF. Block the two rear wheels.
Jack up both sides of the front axle and support it
with jack stands.
Clean the area around the hydraulic oil filter and
remove the filter (Fig. 41).
Remove the tube that connects the axle housing to
the transmission and allow the oil to flow into a drain
pan.
Install new hydraulic oil filter and connect the tube
between axle housing and transmission. Fill axle
(reservoir) to proper level (approx. 5 qt); refer to Check
Hydraulic System Fluid. Remove jack stands.
Start engine, cycle steering and lift cylinders, and
check for oil leaks. allow engine to run for about five
minute. Then shut engine off.
After two minutes, check level of transmission fluid;
refer to Check Hydraulic System Fluid.

Adjust the service brakes when there is more than one
inch (25 mm) of free travel" of the brake pedals, or
when the brakes do not work effectively. Free travel is
the distance the brake pedal moves before braking
resistance is felt.
The brakes should be checked for adjustment after the
first 25 hours of operation and should only need
adjusting after considerable use thereafter. These
periodic adjustments can be performed where the
brake cable connect to the bottom of the brake pedals.
When the cable is no longer adjustable, the star nut on
inside of the brake drum must be adjusted to move the
brake shoes outward. However, the brake cables must
be adjusted again to compensate for this adjustment.
Disengage lock arm from right brake pedal so both
pedals work independently of each other.
To reduce free travel of brake pedals Ċ tighten the
brakes Ċ loosen front nut on threaded end of brake
cable (Fig. 42). Then tighten rear nut to move cable
backward until brake pedals have 1/2 to 1 inch (13 mm
to 25 mm) of free travel. Tighten front nut after brakes
are adjusted correctly.
