Operator's Manual

Hydraulic Lift System (continued)
• 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 -37 to -43°C (-35 to -46°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 (2/3 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 Toro Dealer.
Checking the Hydraulic-Fluid Level for the Lift System
1. Park the machine on a level surface, move the motion-control levers to the NEUTRAL-LOCK
position, engage the parking brake, rotate and raise the hopper, and install the cylinder
lock.
2. Shut off the machine and remove the key. Allow the machine to cool completely.
3. Remove the filler cap from the reservoir tank.

4. Look inside the tank to check the fluid level.
Note: If the machine is cool, the fluid should be at the cold level; if the machine is
hot, the fluid should be at the hot
level.
