The backhoe is bolted to the subframe. The hour meter says 433 but there is not a fourth digit so I cannot be sure. I have put about 50 hours on it this year and I am the second owner.

Looking to sell my 1990 Kubota B9200HST 4WD. I’ve moved 80 tons of rock and dirt in the last 6 months and taken 3 acres of trees down with the help of the tractor. I’ve added three 200 foot French drains to my house with help of the 13hp backhoe and saved my basement. My little farm has grown...

I looking to sell mine. It’s fully functional and running.

Beyond frustrated with this tractor. It is demonically possessed! I’ve done nothing except get the lift arms lowered and opened the valve under the seat. Now, it gets stuck in forward and reverse(no longer a nuetral?). I nearly drove straight through my new metal building. I haven’t even...

Wolfman, Thanks for the quick response. I plan to just throw parts at the problem and see what happens. I don’t believe I need a hydraulic pump because the pressures are within tolerance. I’m leaning toward the control lever and the valves. Do you believe the HST is still the issue? I’m...

Wolfman, Finally attached the pressure gauge and did some diagnostics. First, the highest system pressure I can achieve is 1950psi with the FEL max out in the dump position and in reverse. I think that is a little low. Next, the directional control nut. I turned it in every possible...

I turned it all the way clockwise and the FEL shut off completely. The tractor still moved but I didn’t really notice a performance improvement. I did not look to see if the rear lift arms moved nor did I try to move them. However, when I opened the diverter nut (full counter clockwise) the FEL...

More photos I wanted to include photos of my BH to clear up earlier posts about the BH hydraulics not being a factor and it a subframe mounted BH. Thanks.

Wolfman, Apologies for messing up the acronym "FEL". Thanks for the correction. Yesterday, I had a breakthrough. I turned the Implement Lowering Speed Control knob all the way in (clockwise) and lowered the Position Control Lever. The tractor immediately performed with nearly full power...

B9200 HST 4WD Hydraulic Issue continues After three HST flushes, the watery crappy fluid is fixed. I took the tractor to local small engine repair shop and they were completely useless in diagnosing my inability to operate the tractor up a hill with a load or in any other range besides low...

Wolfman, Without sounding like a cheap ass, I can’t find a hydraulic pressure guage capable of 5000psi on Amazon or eBay for less than $100. Any suggestions would be awesome.

Update #17 Great news! After another flush (that’s three if you’re counting...) and can of seafoam, the fluid isn’t milky anymore. The tractor seems to run better and is quieter. However, I moved the position control lever down and the lift arms stayed up. My BH is not connnected. As I was...

More photos. Looks like I’ve lucked out and have the lower serial number tractor (THANK GOD!!). You can see my PTO driven BH and the position control is jacked up and locked. Again, I’ll “try” to flush the fluid and see if a miracle occurs. Thanks

Update #4: This is a photo of the hydraulic fluid after the second flush and filter. I ran the tractor for a couple hours today and pulled some logs. It’s moves better but still struggles up hills even in low. I was able to climb a small grade tonight without any load. I’m going to keep...

How are you getting the parts diagrams off of the Coleman site? It only lets me view oil filters for the B9200HST.

Update #3: Completely drained the entire hydraulic system all weekend. Added new fluid and the tractor appears to move a little better. I still can’t climb a hill of any grade in medium or high range. It will move faster on flat ground now. The PTO driven BH pump does NOT stop when the...

It’s a woods backhoe and mounted to the subframe. There’s an aftermarket auxiliary PTO driven pump. I’ll post photos of the entire thing tonight. Thanks

Gentlemen, I’ve picked up another 5gal jug of crap fluid to flush my zombie HST with. Yes, my BH is running off the PTO shaft. Yes, my position control lever is jacked up to the sky and I’m fearful that’s the real problem. I don’t understand why it’s locked up. I’ll flush the tranny tonight and...

200mph, Thanks for the quick reply and help with understanding the PTO diagnosis. I’ve opened all the drain plugs (two in rear axle and one at the mid PTO) and drained more milky fluid out. About 8oz of pure water cans out of the rear axle plug. This was after draining it two day ago and...
