Hydraulic Fluid
Specifications
The reservoir is filled at the factory with high-quality
hydraulic fluid. Check the level of the hydraulic fluid
before you first start the engine and daily thereafter;
refer to Checking the Engine-Oil Level (page
Recommended hydraulic fluid: the manufacturer
PX Extended Life Hydraulic Fluid; available in 19 L (5
US gallon) pails or 208 L (55 US gallon) drums.
Note:
A machine using the recommended
replacement fluid requires less frequent fluid and filter
changes.
Alternative hydraulic fluids: If the manufacturer
PX Extended Life Hydraulic Fluid is not available,
you may use another conventional, petroleum-based
hydraulic fluid having specifications that fall within the
listed range for all the following material properties
and that it meets industry standards. Do not use
synthetic fluid. Consult with your lubricant distributor
to identify a satisfactory product.
Note:
the manufacturer does not assume
responsibility for damage caused by improper
substitutions, so use products only from reputable
manufacturers who will stand behind their
recommendation.

Note:
Many hydraulic fluids are almost colorless,
making it difficult to spot leaks. A red dye additive for
the hydraulic fluid is available in 20 ml (0.67 fl oz)
bottles. A bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic fluid. Order Part No. 44-2500

Biodegradable Hydraulic Fluid is the only
synthetic biodegradable fluid approved by Toro.
This fluid is compatible with the elastomers used
in Toro hydraulic systems and is suitable for a
wide-range of temperature conditions. This fluid is
compatible with conventional mineral oils, but for
maximum biodegradability and performance, the
hydraulic system should be thoroughly flushed
