level of the fluid. The fluid level should be within
6 mm (1/4 inch) of the mark on the dipstick.
4.
If the level is low, add the appropriate fluid to
raise the level to the full mark.
5.
Install the dipstick and cap onto the filler neck.
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 Hydraulic Fluid (page 46)
.
Recommended hydraulic fluid:
Toro 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 Toro 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:
Toro does not assume responsibility for
damage caused by improper substitutions, so use
products only from reputable manufacturers who will
stand behind their recommendation.

Viscosity Index ASTM D2270
140 or higher
Pour Point, ASTM D97

Industry Specifications:
Eaton Vickers 694 (I-286-S,
M-2950-S/35VQ25 or
M-2952-S)
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
from your authorized Toro distributor.
Important:
Toro Premium Synthetic
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 of
conventional fluid. The oil is available in 19 L (5
US gallons) pails or 208 L (55 US gallons) from
your authorized Toro distributor.
Hydraulic Fluid Capacity
32 L (8.5 US gallons); refer to

Changing the Hydraulic
Fluid
Service Interval:
Every 2,000 hours—
If you
are using the recommended
hydraulic fluid,
change the
hydraulic fluid.
Every 800 hours—
If you are not using the
recommended hydraulic fluid or have ever
filled the reservoir with an alternative fluid,
change the hydraulic fluid.
If the fluid becomes contaminated, contact a Toro
distributor to flush the hydraulic system. Contaminated
hydraulic fluid looks milky or black when compared to
clean fluid.
1.
Park the machine on a level surface, lower the
cutting units, shut off the engine, engage the
parking brake, and remove the key.
2.
Open the hood.
3.
Remove the drain plug from the bottom of the
reservoir (
) and let the hydraulic fluid
flow into a drain pan.
