7.3 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
reservoir cap. Remove the cap from the hydraulic
oil reservoir.
2. Visually check the level of hydraulic oil. Hydraulic
oil must be at least 2-1/4" inches from top of the filler
neck. If the level cannot be determined visually, use
a clean tape measure to check the level. If the fluid
is low, add 20W50 motor oil. DO NOT overfill;
(overfilling the oil reservoir may cause oil seepage).
3. Clean the fill cap and install it onto the reservoir.
Figure 7-2 Hydraulic Oil Reservoir
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.
-Note-
The hydraulic 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. Place a suitable container under the hydraulic oil
filter. Remove the cap from the tee installed in the
hydraulic oil filter head. (Figure 7-2). Allow the fluid
to drain into the container and properly discard it.
3. Remove the oil filter element (Figure 7-2) and
properly discard it. Fill the new filter with clean oil
and install the filter. Hand tighten only.
4. Install the cap onto the tee and be sure it is tight.
5. Remove the fill cap from the reservoir and fill the
reservoir to 2-1/4" inches from the top of the filler
neck with 20W50 motor oil.
6. Replace the reservoir fill cap.
7. Start the engine and drive forward and backward for
two minutes. Check the oil level in the reservoir. If
necessary, add oil to the reservoir.
7.4 ENGINE OIL
A. Checking Engine Crankcase Oil Level
The engine oil level should be checked after every 8
hours of operation or daily as instructed in the Engine
Operators Manual furnished with this mower.
B. Changing Hydraulic Oil

hours or annually, whichever occurs first. The oil should
also be changed if the color of the fluid has become
black or milky.
