4. Install expansion tank cap.
Checking the Hydraulic System
The machines reservoir is filled at the factory with
approximately 3.5 U.S. gallons (13.2 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:
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.
High Viscosity Index/Low Pour Point Antiwear
Hydraulic Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM D2270 140 to 160
Pour Point, ASTM D97
Industry Specifications:
Vickers I–286–S (Quality Level), Vickers M–2950–S
(Quality Level), Denison HF–0
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
This is vegetable–oil based biodegradable oil tested and
approved by Toro for this model. This fluid is not as
resistant to 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
(Fig. 30). 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.
Check Tire Pressure
The tires are over–inflated for shipping. Therefore, release
some of the air to reduce the pressure. Correct air pressure
in tires is 14 –18 psi.
Important
Maintain recommended pressure in all tires
to assure a good quality–of–cut and proper machine
performance.
Danger
Low tire pressure decreases the machine's sidehill
stability. Do not under inflate tires. This could
cause a rollover, which may result in personal
injury or death.
Check Reel To Bedknife
Contact
Each day before operating, check reel to bedknife contact,
regardless if quality of cut had previously been acceptable.
There must be light contact across the full length of the reel
and bedknife (refer to Adjusting Reel to Bedknife in
Cutting Unit Operator's Manual).
