Hydraulic System Maintenance; Checking The Hydraulic System - Toro 30695 Operator's Manual

Hydraulic System
Maintenance
The reservoir is filled at the factory with approximately
4.7 liters (5 quarts) of high quality tractor
transmission/hydraulic fluid. The recommended
replacement fluid is as follows:
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, Mobil® 424
hydraulic fluid may be used.
Note: Toro will not assume responsibility for damage caused
by improper substitutions.
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. One bottle is
sufficient for 15-22 liters (4-6 gallons) of hydraulic oil. Order
part number 44-2500 from your Authorized Toro Distributor.
