I am just now mounting my first snow blade and thinking about stress loads. It sure seems like there would be a tremendous amount of side load if one side or the other of the blade would hit sometiong hard. I am thinking about mounting an inverted u shaped slot in the front of the tractor so the blade can be lifted ,yet be limited to sideways travel. Thanks to pullstart's suggestion on shimming the rear mounts, the blade has decent upward travel.
i will give it a try and come back with piccs. Anyway I gotta show off those off road tires I got for $40.00 from the sale barn
