Hey, I purchased a B2650 and while I was towing it home the cab roof blew off on the highway. Luckily the roof never hit another car or caused an accident. While loading the tractor and attachments onto the trailer and truck I never thought that I should have strapped my roof down to keep it from blowing off. The wind must have caught the roof and ripped all ten of the nutserts out of the plastic roof. I priced a new roof, and it is around $1,500 Canadian, I think I can fix it though. Has anyone else heard of this happening, the dealers I spoke to have not and I have never noticed tractors being towed on the highway with their cabs strapped down.
