Hydraulic Specification
The machine is shipped from the factory filled with high-quality hydraulic fluid. Check the level of hydraulic fluid before the machine is first started and daily thereafter. The recommended replacement fluid is as follows:
Toro Premium Transmission/Hydraulic Tractor Fluid (Available in 5 gallon pails or 55 gallon drums. See parts catalog or Toro distributor for part numbers.) |
Alternative fluids: If the specified fluid is not available, other universal tractor hydraulic fluids (UTHF) may be used, but they must be only conventional, petroleum-based products, not synthetics or biodegradable fluids. The specifications must fall within the listed range for all the following material properties and the fluid should meet listed industry standards. Check with your fluid supplier to see if the fluid meets these specifications.
Note: Toro assumes no responsibility for damage caused by improper hydraulic fluid substitutions, so use only products from reputable manufacturers who stand behind their recommendation.
Material Properties: | |
Viscosity, ASTM D445 | cSt @ 40°C (104°F) 55 to 62 |
Viscosity Index ASTM D2270 | 140 to 152 |
Pour Point, ASTM D97 | -37°C to -43°C (-35°F to -46°F) |
Industry Specifications: 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 oil is available in 20 ml (2/3 fl oz) bottles. 1 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 distributor.
