Hydraulic System
Maintenance
The reservoir is filled at the factory with approximately
4.7 liters (5 quarts) 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 20 ml (2/3 oz) bottles. One bottle is
sufficient for 15-22 liters (4-6 gallons) 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.
2. Place the controls in the neutral locked position and
start the engine.
Note: Run engine at lowest possible RPM to purge
the system of air. Do not engage the PTO.
3. Raise the deck to extend lift cylinders, stop the engine,
and remove the key.
4. Raise the seat to access the hydraulic fluid tank.
5. Remove the hydraulic fill cap
neck.
