Hit a rock just below the deep snow surface. Rock profile (frozen river) was like a cement block. About 30 mph. Sled stopped instantly and spun 90 degrees. I kept going 20 feet further.
Doing something I shouldn't have been doing.
Amazingly, the last photo shows what I have to replace. About 600 bucks worth. Bulkhead, mounting studs all ok as you can see. Bravo Polaris!
Thank goodness I'm not hurt (sore tho).
