I'm having problems with my blower this year on my 800. The problem is in the gear case. The pin that goes through the gear and input shaft inside the housing keeps breaking. It happened 3 times in the last 2 weeks. It is not that I'm pushing it too hard since we have not had enough snow for that. Every time I am just "playing" in about 1 or 2 inches of snow, paitently waiting for more. I never had this problem before running it on the 800 or my old G10. I did put a knew PTO belt on recently. I don't think it would shear off the pin though if it was not adjusted right. Any thoughts on the matter would be appreciated as I'm getting sick of pulling of the gearbox to replace the pin, But I am now getting good at it. lol.
