• Toro Premium All Season Hydraulic Fluid
(refer to your Authorized Toro Dealer for more
information)
• If either of the above Toro fluids are not
available, you may use another Universal Tractor
Hydraulic Fluid (UTHF), but they must be only
conventional, petrolium-based products. The
specifications must fall within the listed range for
all of the following material properties and the fluid
should meet the listed industry standards. Check
with your oil supplier to determine if the oil meets
these specifications.
Note: Toro will not assume responsibility for
damage caused by improper substitutions, so use
only products from reputable manufacturers who
will stand behind their recommendations.
Material Properties
Viscosity, ASTM D445

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 gal (15-22
l) of hydraulic oil. Order part no. 44-2500 from your
