7.2 HYDRAULIC SYSTEM

A. CHANGING HYDRAULIC OIL

The hydraulic system oil and filter should be changed after 
the first 75-100 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.

- 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 7-1. Clean any 
loose debris around the perimeter of the filter.

REMOVE SCREWS AND
OIL FILTER GUARD

REMOVE OIL
FILTER

Figure 7-1. Hydraulic Oil Filter and Drain Plug

3.  Place a suitable container under the hydraulic oil 

filters. 

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 7-2.

5.  Once the hydraulic system has drained, install new 

hydraulic oil filters to both axles by hand, turn 3/4 
to one complete turn after filter gasket contacts the 
filter base.

6.  Reinstall the filter guards and torque the screws to 

65 in/lbs.

7.  Remove the side top port plug from both transaxles 

before filling with oil. See Figure 7-2.

REMOVE TOP
PORT PLUG

Figure 7-2. Top Port Plug Location

8.  Remove the fill port plug from the top of both 

transaxle. See Figure 7-3. Fill each transaxle with 
Scag Hydraulic System Oil (p/n 486255 - 1 Quart or 
p/n 486254 - 1 Gallon) oil until the oil just appears 
at the bottom of each axle top port. Approximately 2 
quart capacity per transaxle (4 quart total). Reinstall 
the top port plugs and torque to 180 in/lbs.
