Ariens 910995 bucket, 910962 tractor is leaking gear oil from the rear of the differential going to the impeller, on the bucket. I have not split the blower from the tractor yet, so, I don't know what is involved with this seal replacement. I plan to take this apart this coming week end. I looked at a parts diagram (Partstree) and it looks like the seal is at the rear of the differential assembly. If that is the case, it looks like an straight forward replacement. Any help on what I will be getting into is appreciated.
