Servicing the Hydraulic System

The hydraulic system is designed to operate on anti-wear
hydraulic fluid. The hydraulic reservoir is filled at the
factory with approximately 4-1/2 gallons (17 liters) of
ISO VG 46/48 hydraulic fluid. The appropriate hydraulic
oils are listed below.
Important
Use only the types of hydraulic fluids
specified. Other fluids could cause system damage.
Note: A red dye additive for the hydraulic system oil is
available in 2/3 oz. bottles. One bottle is sufficient for
4–6 gallons of hydraulic oil. Order Part No. 44-2500 from
your Authorized Toro Distributor. We do not recommend
the use of red dye additive for biodegradable fluid. Use
food coloring instead.

Important Group 1 fluids are recommended for use at
typical ambient temperatures of 32°F (0°C) to 105°F
(41°C). The ISO Type 46/48 fluid has been found to offer
optimal performance in a wide range of temperature
conditions for the average user. The Universal Tractor
Fluids offer similar performance for those who prefer them,
with perhaps some slight loss of efficiency at high ambient
temperatures compared to the Type 46/48 fluids.
