B8200 HST VERY LITTLE POWER TO WHEELS

[Banjo]

(B8200 HST) 50 HOURS ON THE UNIT. HYDRAULIC OIL HAS BEEN CHANGED (KUBOTA BRAND), HYDRAULIC FILTER HAS BEED CHANGED (KUBOTA BRAND), SCREEN HAS BEEN CLEANED (NOTHING IN IT), HYDRAULIC OIL LEVEL IS FULL, PTO NEVER GIVES UP, 3 POINT HITCH NEVER GIVES UP AND HAS PLENTY OF POWER, ENGINE SPEED NEVER DECREASES, FORWARD AND REVERSE RELIEF VALVES HAVE BEEN SWAPPED ALONG WITH NEUTRAL VALVES. AS THE OIL WARMS, IT WILL HARDLY PULL ITSELF IN HIGH GEAR ON FLAT GROUND, IN MEDIUM WITH A SLIGHT INCLINE IT BARELY CRAWLS AND LOW SPEED WILL STALL OUT IF THE OIL IS WARM AND POWERING A FINISH MOWER. I REALLY LOVE THIS LITTLE TRACTOR BUT IT IS GETTING UNDER MY SKIN QUICKLY.

IS THERE ANOTHER SCREEN THAT I AM MISSING. EVERYTHING THAT I HAQVE CHANGED INCLUDING THE OIL AND FILTERS HAS LOOKED BRAND NEW WITH NO DEBRIS IN THE SYSTEM.

THE UNIT DOES NOT HAVE A LOADER.

You have a B8200 HST with only 50 hours on it? I had one for 35 years that had about 60-70 hrs a year mowing. Are you sure about the hours?

The B8200 has a 3 digit hour meter and it's common for them to wrap over to zero. Also the cable going to the hour meter can snap. It likely has 1050hours or more.

A good HST should pull the tractor by itself up an incline in high gear.

Based on the issues with the HST happen when the oil warms up, it sounds like the HST could be worn out. The cold oil is move viscous and "fills" the gaps from the worn out parts and operates almost normal; when the oil warms up it moves freely in these gaps and produces reduced performance.

I wouldn't expect a worn out HST to stall the tractor. Does it stall without the PTO engaged in any speed range?
