Drive Pulley Replacement

The drive pulleys must be replaced to change between
high speed and standard speed.
Before changing the drive pulleys, follow Drive Belt
Replacement or Hydraulic Belt Replacement (Electric
Models only), page 22, to remove and replace the belt
cover, drive belt, and drive pulleys from the machine.
Flail drums must be used only on standard speed
machines. Using flail drums on high speed machines
will damage the drum and may cause serious injury.
Gas/Propane Models
Standard Speed: Use the 28-tooth pulley on the engine
shaft and the 56-tooth pulley on the drum shaft. Use the
1120 mm belt.
High Speed: Use the 48-tooth pulley on the engine shaft
and the 48-tooth pulley on the drum shaft. Use the 1160
mm belt.
