Hydraulic System
Maintenance
The reservoir is filled at the factory with
approximately 5 quarts (4.7 l) of high quality tractor
transmission/hydraulic fluid. The recommended
replacement fluid is as follows:
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,
Mobil® 424 hydraulic fluid may be used.
Note: Toro will not assume responsibility for damage
caused by improper substitutions.
Note: Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic system oil is available in 2/3 oz. (20 ml)
bottles. One bottle is sufficient for 4-6 gal (15-22 1) of
hydraulic oil. Order part number 44-2500 from your
authorized Toro distributor.
Checking the Hydraulic
System
Service Interval: Before each use or daily
Check the level of the hydraulic fluid before the engine
is first started and daily thereafter.
1. Position the machine on a level surface. Place the
controls in the neutral locked position and start the
engine. Run engine at lowest possible RPM to purge
the system of air. Do not engage the PTO. Raise
the deck to extend lift cylinders, stop the engine, and
remove the key.
2. Raise the seat to access the hydraulic fluid tank.
3. Remove the hydraulic fill cap (Figure 69) from filler
neck.
