Note: Oils within this group are inter-
changeable.
IMPORTANT: Two groups of hydraulic oil are
specified to allow optimal operation of the
machine in a wide range of temperatures
encountered. The group 1 oils are a multi-
viscosity hydraulic oil that allow operation at
lower temperatures without the increased
viscosity associated with straight viscosity oils.

Using the Mobil 424-type oils in the higher ambient
temperatures may result in decreased efficiency in
some hydraulic components compared to using the
Mobil DTE 26 type oils.
The Mobil DTE 26 type oils are straight viscosity
oils which remain slightly more viscous at higher
temperatures than the multi-viscosity oils.
Using the Mobil DTE 26 type oils in the lower
ambient temperatures may result in harder starting,
increased engine laboring while cold, sluggish or
non-operating valve spools while cold and increased
filter back pressure due to the higher oil viscosity.
Select the set of conditions (either ambient
temperatures above 21° C or below 38° C, and use
that type of oil throughout the year, rather than
changing oil types several times per year.
Group 3 Hydraulic Fluid (Biodegradable):
ISO VG 32/46 anti-wear Hydraulic fluid
Mobil
Note: This biodegradable hydraulic fluid in this
group is not compatible with the fluides in group 1
or 2.
Note: When changing from one type of hydraulic
oil to the other, remove all the old oil from the
system, because some brands of one type are not
completely compatible with some brands of the
other type of hydraulic oil.
IMPORTANT: Use only the types of hydraulic
oils specified. Other fluids could cause system
damage.
Note: A red dye additive for the hydraulic system
oil is available in 20 ml bottles. One bottle is
sufficient for 15–22 l of hydraulic oil. Order Part
No. 44-2500 from your Authorized Toro Distributor
1. Position the machine on a level surface, lower
the cutting units and stop the engine.
2. Clean the area around the filler neck and cap of
the hydraulic tank. Remove the cap from the
filler neck.
