The axle housing acts as the reservoir for the system.
The transmission and axle housing are shipped from
the factory with approximately 6 quarts (5.6 l) of high
quality hydraulic fluid. Check the level of hydraulic
fluid before the engine is first started and daily
thereafter. The recommended replacement fluid is:
Toro Premium Transmission/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 41 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 responsibility for damage
caused by improper substitutions, so use only products
from reputable manufacturers who will stand behind
their recommendation.

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
