Thanks for the post. Ended up shortening the plastic bushings as well and added a second set of OEM dust seals to the inner rear axle. Didn't epoxy anything as the seals had a really snug fit and haven't popped out. Also did the felt mod. A couple mows in so far, with no issues...yet. Will be blowing the mower off to clean it and avoiding wet grass if at all possible. Man, this mower is HEAVY and certainly not a lightweight!
Has anyone noticed when using the mulch plug, that the clippings exit in earnest around the left rear drive wheel? Maybe it's just me, but the clippings discharge from under the deck right in this area.
