HYDRAULIC SYSTEM

A. CHECkING HYDRAULIC OIL LEvEL
The hydraulic oil level should be checked after the first 10
hours of operation. Thereafter, check the oil after every
200 hours of machine operation or monthly, whichever
occurs first.
- IMPORTANT -
If the oil level is consistently low, check for leaks
and correct immediately.
1. Wipe dirt and contaminants from around the
hydraulic level indicator window.
2. Visually check the level of hydraulic oil. Hydraulic
oil must be within the center of the wide postion of
the indicator window when the machine is cold. See
Figure 7-2. If the fluid is low, add 20W50 motor oil.
DO NOT overfill; (overfilling the oil reservoir may
cause oil seepage around the cap area).

B. CHANGING HYDRAULIC OIL AND FILTER
The hydraulic oil should be changed after every 500 hours
or annually, whichever occurs first. The oil should also
be changed if the color of the fluid has become black or
milky. A black color and/or a rancid odor usually indicates
possible overheating of the oil, and a milky color usually
indicates water in the hydraulic oil.

Park the mower on a level surface and stop the
engine.
Position a floor jack under the rear of the machine.
Raise the machine and support it to prevent it
from falling. Block the caster wheels to prevent the
machine from moving.
Place a suitable container (capable of holding 6
quarts) under the RH hydraulic axle assembly.
Remove the cover over the hydraulic reservoir
located on the LH fuel tank. Remove the fill cap from
the reservoir and the drain plug from the bottom
of the RH hydraulic axle assembly. See Figure
7-3. Allow the fluid to drain into the container and
properly discard it.
