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.
