Hydraulic System
Maintenance
The reservoir is filled at the factory with approximately 4.7 L
(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 fluid is available in 20 ml (2/3 fl oz) bottles. One
bottle is sufficient for 15 to 22 L (4 to 6 gallons) of hydraulic
fluid. Order part number 44-2500 from your Authorized
Toro Distributor.
Hydraulic System Safety
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Ensure that all hydraulic-fluid hoses and
lines are in good condition and all hydraulic
connections and fittings are tight before
applying pressure to the hydraulic system.
• Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure
hydraulic fluid.
• Use cardboard or paper to find hydraulic leaks.
• Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
• Seek immediate medical attention if fluid is
injected into skin.
Checking the Hydraulic
System
Service Interval: Before each use or daily
Check the level of the hydraulic fluid before you first start the
engine and daily thereafter.
1. Position the machine on a level surface.
2. Move the motion-control levers to the N
position and start the engine.
