Was the HST failure premature on your B21, because of lack of service or some other reason; I would think the life cycle should be longer? Kubota always does a lengthy field tests? Maybe contamination of some kind or sabotage by a disgrunted person?? Have you been able to determine the cause of damage, or was it more than the HST that caused the rebuild?

DAVE: When you opened the HST and said things were "within limits:" meaning to me; it was warn, but would "maybe" need rebuilding in the distant future too?

This goes back> than 5 yrs here, but one of the members had a fleet of Kubota HST's for side road maintenance somewhere in Canada, towing small trailers, and complained of poor performance in fuel and capability on long steep pulls, (high fluid temps) I think?...that got my attention? I believe he traded-out for gears? I may buy a small new HST in the future for mowing and gardening.
