oil level when the fluid is cold.
2. Check expansion reservoir and if necessary
add Toro

Changing the Hydraulic
Fluid and Filters
Service Interval: After the first 75 hours—Change the
hydraulic-system filters and fluid.
Every 250 hours—After the initial
change—change the hydraulic-system
filters and fluid when using Mobil 1 15W50
fluid. (Change it more often under dirty or dusty
conditions)
Every 500 hours—After the initial
change—change the hydraulic-system
filters and fluid when using Toro
® HYPR-OIL ™
500 fluid. (Change it more often under dirty or
dusty conditions)
To replace the hydraulic fluid, the filters need to be
removed. Replace both at the same time; refer to
Hydraulic Fluid Specifications (page 51) for fluid
specifications.
Purge any air in the system after you install the new
filters and add fluid. Refer to
Bleeding the Hydraulic
System (page 54) . Repeat the bleeding process until
the fluid remains at the F
ULL
C
OLD
line in the reservoir
after purging. Failure to properly perform this
procedure can result in irreparable damage to the
transaxle drive system.
Removing Hydraulic-System
Filters
1. Park the machine on a level surface, disengage
the blade-control switch (PTO), and engage the
parking brake.
2. Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3. Allow the engine to cool.
4. Locate the filter and guards on each
transaxle-drive system (
Figure 69 ).
5. Remove the 3 screws securing the filter guard
and guard (
Figure 69 ).

fluid that drains when the filter and vent plugs
are removed.
8. Locate and remove the vent plug on each
transmission
9. Unscrew the filter to remove it, and allow the
fluid to drain from the drive system.
