Checking the
Hydraulic-Fluid Level
Service Interval: Before each use or daily
The hydraulic tank of the machine is filled at the
factory with approximately 37.8 L (10 US gallons) of
high quality hydraulic fluid. Check the level of the
hydraulic fluid before the engine is first started and
daily thereafter. The recommended replacement fluid
is as follows:
Toro Premium All Season Hydraulic Fluid (Available in
18.9 L (5 US gallon) pails or 208 L (55 US gallon) drums.
See the Parts Catalog or your Toro Distributor for part
numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We
do not recommend the use of synthetic fluid. Consult
with your lubricant distributor to identify a satisfactory
product.
Note:
Toro will not assume responsibility for damage
caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
High Viscosity Index/Low Pour Point
Anti-wear Hydraulic Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM
D2270
Pour Point, ASTM D97
Industry Specifications:
Important:
The ISO VG 46 Multigrade fluid
has been found to offer optimal performance
in a wide-range of temperature conditions.
For operation in consistently high ambient
temperatures, 18°C (65°F) to 49°C (120°F),
ISO VG 68 hydraulic fluid may offer improved
performance.
Premium Biodegradable Hydraulic Fluid-Mobil
EAL EnviroSyn 46H
Important:
Mobil EAL EnviroSyn 46H 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) containers or 55 gallon drums from
your Mobil Distributor.
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. 1 bottle is sufficient for 15 to 22 L (4 to 6 US
gallons) of hydraulic oil. Order Part Number 44-2500
from your Toro Distributor.

Position machine on a level surface, lower the
cutting decks and stop the engine.
2.
Clean area around filler neck and cap of

3.
Remove cap/dipstick from filler neck and wipe
it with a clean rag. Insert dipstick into filler
neck; then remove it and check level of fluid.
Fluid level should be within operating range on
dipstick. Do not overfill.
4.
If level is low, add appropriate fluid to raise level
to full mark.
5.
Install cap/dipstick onto filler neck.
