then lower the boom until the track is raised off the
ground. Place a block under the undercarriage and
raise the attachment off the ground.
2. Set the engine speed lever to the maximum speed
position.
3. Operate the travel control lever to move the raised
track forward and backward and shake off the mud.
4. Repeat the same operations for the other track.
