23.2. The hydraulic reservoir is accessible by tipping-
up the seat. See Figure 23.2.
• Always clean the area surrounding the hydraulic
fluid fill-cap / dipstick before removing the cap.
Clean the area around any hydraulic fitting that
are to be disconnected including hoses and filter.
• The reservoir contains 2 Qts. (1.89 L) of 5W40
synthetic hydraulic fluid (hydraulic drive system
fluid plus p/n: 737-3121), and the filter contains
roughly a pint (.47 L) of fluid. Total system
capacity is more.
• The fluid and filter should be changed after the
first 50 hrs. of operation, and after each 500 hrs.
of operation following the initial change.
23.3. Removing the hydro service plate using a 7/16”
wrench provides access to the reservoir and the
hoses that connect to it. See Figure 23.3.

• The hose connected to the shorter tube at the
front of the tank is the return line.
• The hose connected to the longer tube at the
rear of the tank is the pick-up line, feeding the
hydrostatic pumps via the filter.
23.4. The hydraulic filter is mounted beneath a bracket
just in front of the reservoir. It is accessible for
service from below the frame. See Figure 23.4.
23.5. The filter and housing are direction-specific. If
the hoses are disconnected for service, confirm
correct reattachment before operating the
mower. See Figure 23.5.
23.6. When changing hydraulic fluid, most of the res-
ervoir will syphon out through the filter housing
once the filter is removed.
23.7. Disconnect the return lines at the T fitting near
the reservoir to drain them.
