1. Fuel tank cap
4. Fill the tank until the level is to the bottom of the
filler neck with diesel fuel.
5. Install fuel tank cap tightly after filling tank.
Note: If possible, fill the fuel tank after each use.
This will minimize possible buildup of condensation
inside the fuel tank.

Checking the Hydraulic Fluid

Service Interval: Before each use or daily
The machines reservoir is filled at the factory with
approximately 8.5 U.S. gallons (32 l) of high quality
hydraulic fluid. Check the level of the hydraulic fluid
before the engine is first started and daily thereafter.
The recommended replacement fluid is as follows:
Toro Premium All Season Hydraulic 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, other
fluids may be used provided they meet all the following
material properties and industry specifications. We do
not recommend the use of synthetic fluid. Consult
with your lubricant distributor to identify a satisfactory
product Note: Toro will not assume responsibility for
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.

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 2/3 oz. (20 ml)
bottles. One bottle is sufficient for 4-6 gal (15-22 1)
of hydraulic oil. Order part no. 44-2500 from your
authorized Toro distributor.
Biodegradable Hydraulic Fluid - Mobil 224H
Toro Biodegradable Hydraulic Fluid (Available in 5 gallon
pails or 55 gallon drums. See parts catalog or Toro distributor
for part numbers.)
Alternate fluid: Mobil EAL 224H
Note: This is vegetable-oil based biodegradable oil
tested and approved by Toro for this model. This fluid
is not as resistant to high temperatures as standard
fluid, so install an oil cooler if required by the operator
manual and follow recommended fluid change intervals
with this fluid. Contamination by mineral-based
hydraulic fluids will change the biodegradability and
toxicity of this oil. When changing from standard fluid
to the biodegradable type, be certain to follow the
approved flushing procedure. Contact your local Toro
Distributor for details.
1. Position machine on a level surface, lower the
cutting units and stop the engine.
2. Clean area around filler neck and cap of hydraulic
tank (Figure 34). Remove cap from filler neck.

3. Remove dipstick from filler neck and wipe it with
a clean rag. Insert dipstick into filler neck; then
remove it and check level of fluid. Fluid level should
be within 1/4 inch of mark on dipstick.
4. If level is low, add appropriate fluid to raise level
to full mark.
5. Install dipstick and cap onto filler neck.
