Hydraulic System
Maintenance
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury. Fluid injected
into the skin must be surgically removed
within a few hours by a doctor familiar with
this form of injury; otherwise gangrene may
result.
• Keep your body and hands away from
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks; never use your hands.
Servicing the Hydraulic
Drive System
Expansion-tank capacity: 1.4 L (1.5 US qt)
Hydraulic-fluid type: Toro® HYPR-OIL™ 500
Important:
Always use the correct hydraulic
fluid. Unspecified fluids will damage the hydraulic
system.
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 0.67 fl oz (20
ml) bottles. One bottle is sufficient for 4 to 6 gal (15 to
22 L) of hydraulic fluid. Order Part No. 44-2500 from
your authorized Toro distributor.

the hopper.
2. Shut off the engine, and remove the key. Allow
the engine to cool.
3. Open the cowl.
4. Use the sight window to check the fluid level in
the expansion tank
