Note: A red dye additive for the hydraulic system fluid is
available in 2/3 oz. bottles. One bottle is sufficient for 4–6
gallons of hydraulic fluid. 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.
Group 2 fluids are recommended for heavy-duty use in hot
climates where ambient temperatures range from about
65 F (18 C) to 120 F (49 C). Use at lower ambient
temperatures may result in hard starting, increased engine
laboring while cold, sluggish or non-operating spool
valves while cold and high filter back-pressure due to the
higher viscosity of these fluids.
Note: When changing from one type of hydraulic fluid to
another, be certain to remove all the old fluid from the
system, as some fluids are incompatible with others.
Group 3 Hydraulic Fluid (Biodegradable)
ISO VG 32/46 anti-wear hydraulic fluid
Mobil
Note: This biodegradable hydraulic fluid is not
compatible with the fluids in Group 1 and 2.
Note: An Oil Cooler Kit, Part No. 104-7701, is required
on the traction unit when using the biodegradable fluid.
Fluid temperature should not exceed 180 F (82 C).
Also, regardless of hydraulic fluid type used, any traction
unit used for fairway mowing or used during high ambient
temperatures (65 F (18 C) to 120 F (49 C) should have
an oil cooler installed.
Note: Biodegradable oil is available in 5 gallon (19 l)
containers from your Authorized Toro Distributor. Order
Part No. 100-7674.
Note: When changing from standard fluid to the
biodegradable type, be certain to follow approved flushing
procedures as published by Mobil. Contact your local
Toro Distributor for details.
Filling the Hydraulic Tank
1. Position the machine on a level surface. Make sure the
machine has cooled down so the fluid is cold.
