Hydraulic System
Maintenance
Changing the Hydraulic Oil
And Filter
Service Interval: After the first 10 hours—Change the
hydraulic oil filter. Do not exceed 10
hours or you will damage the hydraulic
system
Every 200 hours—Change the hydraulic oil filter
Every 1,500 hours—Replace the hydraulic oil.
The axle housing acts as the reservoir for the system. The
transmission and axle housing are shipped from the factory
with approximately 5.6 liters (6 quarts) of high quality
hydraulic fluid. Check the level of hydraulic oil before the
engine is first started and daily thereafter. The recommended
replacement oil is as follows:
Toro PremiumTransmission/Hydraulic Tractor Fluid
(Available in 5 gallon pails or 55 gallon drums. See parts
catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
petroleum-based Universal Tractor Hydraulic Fluids (UTHF)
may be used provided its specifications fall within the listed
range for all the following material properties and it meets
industry standards. We do not recommend the use of
synthetic fluid. Consult with your lubricant distributor to
identify a satisfactory product Note: Toro will not assume

Note: Fluid to operate the power steering is supplied by the
hydraulic system transmission charge pump.
Cold weather start-up may result in stiff operation of the
steering until the hydraulic system has warmed up. Using
proper weight hydraulic oil in system will minimize this
condition.
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
