The height of the rear roller wheels can be adjusted to
provide more support for the trailer base. Check the rear
roller wheels periodically and make sure that they are
touching the turntable base. If there is a gap, adjust the
wheels. If your machine vibrates excessively when it is
towed, this is also an indication that the rear roller wheels
should be adjusted.
To adjust the rear roller wheels:
Rotate the feed chute until it is above the hitch and 1.
lock in place.
Push down on the feed chute and keep applying

base to turn freely when released. If it needs further
adjustment, go back to step 2.
