Hydraulic System Maintenance
Hydraulic System Safety
-
Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor.
-
Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.
-
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.
-
Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.
Relieving Hydraulic Pressure
To relieve hydraulic pressure while the machine is on, disengage the auxiliary hydraulics and fully lower the loader arms.
To relieve the pressure while the machine is off, move the auxiliary-hydraulics lever between the forward and reverse flow positions to relieve auxiliary hydraulic pressure, move the attachment-tilt lever forward and rearward, and move the loader-arm lever forward to lower the loader arms (Figure 34).

Hydraulic Fluid Specifications
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 25 hours |
|
Hydraulic Tank Capacity: 56 L (14.8 US gallons)
Use only 1 of the following fluids in the hydraulic system:
-
Toro Premium Transmission/Hydraulic Tractor Fluid (refer to your Authorized Service Dealer for more information)
-
Toro PX Extended Life Hydraulic Fluid (refer to your Authorized Service Dealer for more information)
-
If either of the above Toro fluids are not available, you may use another Universal Tractor Hydraulic Fluid (UTHF), but they must be only conventional, petroleum-based products. The specifications must fall within the listed range for all the following material properties and the fluid should meet the listed industry standards. Check with your hydraulic fluid supplier to determine if the fluid meets these specifications.
Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendations.
Material Properties Viscosity, ASTM D445 cSt at 40°C: 55 to 62 cSt at 100°C: 9.1 to 9.8 Viscosity index, ASTM D2270 140 to 152 Pour Point, ASTM D97 -43 to -37°C (-46 to -35°F) Industry Standards API GL-4, AGCO Powerfluid 821 XL, Ford New Holland FNHA-2-C-201.00, Kubota UDT, John Deere J20C, Vickers 35VQ25 and Volvo WB-101/BM Note: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system fluid is available in 20 ml (0.67 fl oz) bottles. One bottle is sufficient for 15 to 22 L (4 to 6 US gallons) of hydraulic fluid. Order Part No. 44-2500 from your Authorized Service Dealer.
Checking the Hydraulic-Fluid Level
Maintenance Service Interval | Maintenance Procedure |
---|---|
Every 25 hours |
|
Check the hydraulic-fluid level before the machine is first started and after every 25 operating hours.

-
If the level is low, add enough fluid to raise it to the proper level.
-
Install the filler-neck cap.
-
Install the hood/front access cover.
-
Remove and store the cylinder locks and lower the loader arms.
