I originally start the description for this modification in the Ford Forum but now that I see it will work & that others maybe interested in I am moving part of it here. I used some pipe to make a roller for under the snowblower.
Even with gravel piling up in front of the roller no rocks are in the area where the auger turns.
The wear bar extending in front of the roller I am sure helps with this.
The roller does raise the snowblower some but I would think some snow would get pushed up some to.
With some frost in the ground the pile of gravel probably will not be as much of a problem. So more testing will be done then. As an ice base is built up on the driveway I change over to the other slides so that I can lower it as needed.
