Well.. I did 5 hours grooming in Maine yesterday. Trail master told me I was EXCAVATING more than I was grooming. I stand by my decision to go out. I filled in some low holes, and popped out plenty of stumps and rocks.
I also found a few weak spots in the drag.
Found a pivot bolt (big 1" bolt) that had egged out the hole on the drag, then snapped the bolt. Got a nice piece of schedule 40 steel and fixed that right up.
I mounted a piece of plate for a my rear view camera. love that setup.
All in all.. if you can go grooming for 5 hours on virgin trail no one has been on in 8 months or so.... you don't have to winch, only use the chainsaw.... it was a great day grooming.
Studs in the tracks made a huge difference. Icy ledge would have had me winching for sure without them.
