Hello members, Had my snow trac out for the first time in some serious snow (4 feet). Had a problem similiar to snow building up behind rear wheel that I have read about here. But this problem is at the track sprocket. The snow was building up between the two sprockets and raising the track off the teeth of the sprocket. I cleaned it out once and it filled right back up. Left it on the trail I was concerned about breaking axel shaft. Has anyone had a similiar problem? Thanks
