Hydraulic System
Maintenance
The reservoir is filled at the factory with approximately 17
L (18 US qt) 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, you can use
Mobil® 424 hydraulic fluid.
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. A bottle
is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic
fluid. Order Part No. 44-2500 from your Authorized Toro
Distributor.

Hydraulic System Safety

•
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. Injected fluid must be surgically removed
within a few hours by a doctor.

If level is not within notched area of the dipstick, add
enough high-quality hydraulic fluid to raise level to
within the notched area. Do not overfill.
