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.

Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM D2270
Pour Point, ASTM D97
Industry Specications:
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 2/3 oz
(20 ml) bottles. One bottle is sufficient for 4-6

This is vegetable-oil based biodegradable oil tested
and approved by Toro for this model. This fluid is
not as resistant to high temperatures as standard
fluid, so install an oil cooler if required by the
operator manual and follow recommended fluid
change intervals with this fluid. Contamination
by mineral-based hydraulic fluids will change the
biodegradability and toxicity of this oil. When

1. Hydraulic tank cap
4. Remove the dipstick from the filler neck and
wipe it with a clean rag. Insert the dipstick into
the filler neck; then remove it and check the
fluid level. The fluid level should be between
the two marks on the dipstick.
5. If the level is low, add the appropriate fluid to
raise the level to the upper mark.
6. Install the dipstick and cap onto the filler neck.
Checking the Planetary Gear Drive Oil
Check the oil level after every 400 hours of
operation or if external leakage is noted. Use high
quality SAE 85W-140 gear lube as a replacement.
The capacity of the system is approximately 16 oz
(0.5 l).
1. With the machine on a level surface, position
the wheel so that the check/drain plug
(Figure 10) is at either the 2 or 10 o'clock
position.
