7.2 HYDRAULIC SYSTEM
A. Checking Hydraulic System Oil Level
The hydraulic system 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 reservoir.
2. When the machine is "cold" (before operation), visually
check the level of hydraulic system oil. Hydraulic
system oil level should be in the middle of the indicator
window located on the left side of the machine (See
Figure 7-2) . If the fluid is low, add 20W50 motor oil
until the proper level is achieved. DO NOT overfill;
(overfilling the oil reservoir may cause oil seepage).
3. Clean the fill cap and install it onto the reservoir.
B. Changing Hydraulic Oil
The hydraulic system oil should be changed after the first
120 hours of machine operation and every 400 hours or
annually thereafter, 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.
Figure 7-2 Hydraulic System Oil Level
-IMPORTANT-
The hydraulic system oil should be changed if you
notice the presence of water or a rancid odor to the
hydraulic oil.
1. Park the mower on a level surface and stop the engine.
2. Remove the three 1/4” filter guard screws and filter
guard from both axles. (See Figure 7-3). Clean any
loose debris from around the perimeter of the filter.
3. Place a suitable container under the hydraulic oil filters.
Remove the cover from the left side tank to gain access
to the hydraulic reservoir. Remove the fill cap from
the reservoir.
4. Remove the hydraulic filters from both axles and allow
the fluid to drain into the container. Properly discard
the oil when the system has drained completely. (See
Figure 7-3)
