HYDRAULIC SYSTEM MAINTENANCE
CHANGING TRANSAXLE/HYDRAULIC
FLUID:
Change Transaxle/Hydraulic Fluid, filter and clean
strainer every 800 operating hours, in normal
conditions. If fluid becomes contaminated,
contact your local TORO distributor because the
system must be flushed. Contaminated fluid
looks milky or black when compared to clean
fluid.
1.
Park vehicle on a level surface, set the
parking brake, shut engine off, and remove key
from ignition switch. Block the two rear wheels.
2.
Clean area around transaxle/hydraulic fluid
drain plug and remove drain plug from side of
reservoir (See FIG. 24), and let transaxle/hydraulic
fluid flow into drain pan. Reinstall and tighten
plug when hydraulic fluid stops draining.

3.
Fill reservoir through Dipstick opening with
approximately 7.5 qt. (7.1 liters) of Dexron III ATF.
To check the Transaxle/Hydraulic Fluid, see
BEFORE OPERATING, page 18.
4.
Start engine and operate to fill hydraulic
system. Recheck fluid level and replenish, if
required.
IMPORTANT! Use only hydraulic fluids
specified. Other fluids could cause system
damage.
REPLACING TRANSAXLE/HYDRAULIC
FILTER:
Initially, replace the Transaxle/Hydraulic Filter after
10 operating hours, thereafter, replace filter every
800 operating hours.
Use the TORO replacement filter (Part No. 54-
0110).
IMPORTANT! Use of any other filter may void
the warranty on some components.
IMPORTANT! Keeping the Transaxle/
Hydraulic system clean is essential. Servicing
the Transaxle/Hydraulic Filter is critical to the
life of the hydraulic system.
1.
Park vehicle on a level surface, stop vehicle,
engage parking brake, turn engine off, and
remove key from ignition switch.
2.
Clean area around filter mounting area.
Place drain pan under filter and remove filter. (See
FIG. 25)
3.
Lubricate new filter gasket, and
fill the filter
with recommended Transaxle/Hydraulic Fluid.
4.
Make sure filter mounting area is clean.
Screw filter on until gasket contacts mounting
plate. Then tighten filter 1/2 to 2/3 turn.
5.
Start engine and let run for about two
minutes to purge air from the system. Stop the
engine, check the Transaxle/Hydraulic Fluid level,
and check for leaks.
