Well last week i was going through a field and my ski hit a rock or something and broke off. I was going 75 mph when the ski went flying and the sled went out of control. Dented up by bumper bent bith skis broke some vents in the hood. Also my seat must have broken. My seat will pivot back and forth at the front so i was wondering what to do about this. I have taken the seat off and on several times trying to get it to stay but it wont.
