During this shutdown I attended to deferred maintenance on the RTV900 and BX tractor. The HST fluid was drained from both machines and replaced with Super UDT2 and OEM filters.
The RTV HST oil was a clear amber color with just a few particles on the drain plug. I don't know the hours on the oil. During test runs I noticed the engine bog on hills is gone.

The oil from the tractor was dark and had a burnt odor. It was over the recommended 200 hr. limit by about 300hrs. (shame on me). Unlike the RTV this has one filter and a strainer screen on the suction side. The screen had just a few metal particles.
Not sure what the burnt smell was about. The HST fan had few blades missing but fixed that last year.
Any thoughts about possible harm done, seems to run as it should. Should the HST fluid be changed prior to next recommended 200 hr. change interval?
The tractor is mostly for mowing a 1 acre hilly lot and pulling a tree chipper through the woods.
