wheels of the tractor will come to rest when properly locating the plow over the
trailer.
** If slope of the exiting path is too steep (up) due to the installation site, your
dealer may be able to increase the amount of slack to solve this.

Ensure drive-thru is clear of built up mounds of snow.
Ensure the vehicle is exiting at the required speed of 8-10 MPH.
