(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 of 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.

slipping, if it has been replaced, or if it has been
loosened to replace other parts.
1. Place the belt's V-guide in the guides of the front
and rear rollers.
2. Tighten the 2 belt adjustment nuts evenly until
the belt is snug.
Note:
If necessary, remove the front idler roller
cover and the rear chute cover.
3. Fully load the machine with the heaviest material
