First posting for me, I like all the valuable information sharing that is occurring here. First a little Hx, after moving to an acreage/retired Xmas tree farm last year I was blessed with a nod from *the boss* to purchase a 2320 (went in looking @ a 2210) and numerous attachments. Had to upsize since the ROP on the smaller units wouldn't fold/fit in the garage. I have since put about 120 hours on it and use it pretty much everyday. It currently sees alot of brush work, but am about done clearing dead trees. I too have made alot of *rookie* mistakes with her attachments, but it does get smoother with familiarity. One modification I made was to my 62D mmm.
The front turning floater wheels on my deck would scalp my yard when I would go over some uneven spots. The manual reccomends using JD spray lube on the shafts. I would routinely apply said lubricant, to find it really didn't free up the turning shaft. A couple of guys @ work have similar problems with their mmm wheels. This winter I drilled, tapped, and installed grease zerks toward the rear of the housing hoping this would remedy my problem. So far it seems to work pretty slick.
