High Viscosity Index/Low Pour Point Antiwear
Hydraulic Fluid, ISO VG 46
Material Properties:
Viscosity, ASTM D445
Viscosity Index ASTM
D2270
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 number 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 high temperatures as standard fluid, so make
sure to 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. Clean the area around the hydraulic oil reservoir cap
to prevent debris from entering tank (Figure 12).

1. Oil reservoir cap
2. Remove the cap from the reservoir.
3. Check the oil level in the reservoir. The oil level
should be up to the top of the cone point on the
tank screen.
cSt @ 40°C 44 to 48
cSt @ 100°C 9.1 to 9.8
140 to 160
-34°F to -49°F
4. If the fluid level is low, slowly fill the reservoir
with the appropriate hydraulic fluid until the level
reaches the necked down area on the dipstick. Do
not overfill.
5. Install the reservoir cap.
Important: To prevent system contamination,
clean the top of the hydraulic oil containers
before puncturing. Ensure that the pour spout
and funnel are clean.
Checking the Tire Pressure
Service Interval: Before each use or daily
Check the tire pressure before operating the machine
(Figure 13). The correct air pressure in the front and
rear tires are:
• for Treaded tires 4-6 psi (0.3-0.4 bar)
• for Smooth tires 8-10 psi (0.5-0.7 bar)
1. Valve stem
Torque the Wheel Lug Nuts
Service Interval: After the first 8 hours
Every 100 hours
Initially, torque the wheel lugs after the first 8 hours of
operation; thereafter, torque the nuts after every 100
operating hours. Torque the lugs nuts to 45-55 ft-lb
(61-75 N⋅m).
Starting and Stopping the
Engine
1. Remove your foot from the traction pedal, make
sure that the pedal is in the neutral position, and
engage the parking brake.
