Toro Premium Transmission/Hydraulic Tractor Fluid
(Available in 5 gallon pails or 55 gallon drums. See parts
catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, you may use
other petroleum-based Universal Tractor Hydraulic Fluids
(UTHF) provided that its specifications fall within the listed
range for all the following material properties and that it
meets industry standards. 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.

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 15-22 L (4-6 US gallons) of hydraulic oil. Order
