There is a thread similar to this, but it seems focused on JD blowers that use a chain gear reduction on the what I would consider the primary drive side of the blower. Disregard that here.....
My concern is with a 3 pt rear snow blower and the chain that drives the auger to guide snow into the impeller. After each use I try to clean the chain area, ends of the auger, and chain cover from the end of the shaft from the gearbox to the auger where the chain comes through the housing into the auger area.
I view chain, and sprockets in a use like this as consumable items. That is they have a life span and need replaced as needed, not necessarily the same life span of other parts of the implement.
I have seen some brands and models have an upside down L shaped bracket to shield the auger chain sprocket from snow, ice, or what ever. I thought of bolting a similar guard, but got to thinking that would be a prime place for snow to compact and freeze, causing more trouble than good it does.
So, with this info in mind, knock on wood, so far just keeping the chain clean as possible, tension adjusted as it should, and make sure it is moving free before the next use has resulted in no bad experiences. But I want to continue problem free.
Anyone with experience, good or bad with auger drive chains on 3 pt blowers ???
