Plow does not clear snow towards back of
the trailer. Plow not in contact with roof’s
entire length.
Level trailer to reduce slope if front higher than back.
Ensure drive-thru is clear of built-up mounds of snow, particularly where the back wheels of the
tractor will come to rest when properly locating the plow assembly over the trailer.
Slope of the exiting path is excessively inclined. Manually increasing the amount of slack with
another link of chain may resolve this. Or relocate the FleetPlow to a more level location.

trailer.
Level trailer to reduce slope if back higher than front.
