Re: 1991 B7100HST-D 4WD for $700 - Update Great news and congrats! Keep us posted as the repair continues. The flushing with cheap fluid sounds like a good idea. Go to SUDT2 as your final fill and you'll be SET!!!

Sounds like your loader valve body needs a rebuild. There are lots of o-rings and seals in there, and you should be able to order a rebuild kit...though sometimes Kubota makes you buy the whole part...

Tooljunkie, you're 100% correct. You need adequate counterweight/ballast and a skilled operator especially for increased loads. My current hydraulic pressure will lift the back of my machine if I don't have a counterweight...and headed downhill I have had the rear come up multiple...

427cjackson, the good news is that your hydraulic system (at first glance) appears to be fine. If you're able to lift the machine up, especially at idle, you likely have a perfectly good hydraulic pump, good flow through your filters, and a good pressure relief at your pump/machine. Now for...

You have a lot of troubleshooting to do before looking at the pump, or anything else for that matter. If your backhoe has full hydraulic pressure and movement at normal throttle, then you have eliminated a restriction, pump, or pressure relief problem. If it doesn't, then you get continue...

85Hokie, they have the inverter generators now at Harbor freight and Honda/Yamaha have some too. Those are the cats ass.....they are a DC generator that converts to a square sine wave AC...so they are CLEAN power for all electronics...and can idle down with a low load (lower DC voltage and...

I just recently went from UDT to SUDT2 in my 1988ish B9200 and noticed a HUGE difference with the HST whine. My machine also performs better with the SUDT2. How can I tell? I have a hill on my driveway. Headed down the driveway in medium range, at full throttle, the machine used to bog and...

With a grader blade and york rake I have used my B tractor (a BX would work similarly just a bit slower) for installing small gravel driveways (lots of people have kids that get cars and live at home and they outgrow their driveway quickly). Get a dump trailer or pay to have the gravel...

X2 on wolfman's points. That machine was never designed to have a loader, and with 2wd is downright dangerous unless you have a good sized counterweight and loaded tires anyway. Better to get a 4wd machine with a loader. Safer and better overall solution, and will save you $ in the long run.

85Hokie, I mentioned that a few posts earlier, those Kill-o-watt's work perfectly for this task. I used mine to ramp up devices on my 900watt Harbor Freight unit during a 1 week power outage. The generator ran continuously for that week, I added fuel while it ran (it was out in the yard...

Your answer is actually simpler than you think. RPM will = HZ. Buy a "Kill-o-watt" or an electrical meter that measures hertz....as well as voltage. When you get your rpm nailed, you will be at exactly 60hz and in the 110-130v range (or 220-240 if dual pole). If your RPM is too high or low...

Here's the deal from what I have learned with servicing Kubotas for quite a few years in VT, CT and NH. The 80w-90 will work to slow a leaky front axle and will safely lubricate your axle in most conditions. The UDT/SUDT/SUDT2 is more likely to weep by worn seals. HOWEVER, if you live...

Prices on these seem to vary by location. I have a B9200, the predecessor to the B2150 and I vaguely recall paying around $8500 for that with loader and belly mower about 8 years ago. I would suspect they're still around the same price in GOOD condition (working lights, grill intact, etc). A...

Sounds like something internal, maybe differential. However, BEFORE you jump to conclusions, you have a high/low range lever. If a stick got jammed in there and pushed the lever and is keeping it in "neutral", you might have a similar issue. As far as why the fronts move and not rear, thats...

I replaced a few BX senders, its a known issue. A dealer will take care of you if you're in warranty. If not, you will have to buy and replace yourself. Gotta take off the rops, rear fender, etc. Not a horrible job but think if its worth it to "see" that extra 1/4 tank or if you at least...

I've had to work on JD and Kubotas. Parts are usually easier to get for Kubota, prices are more reasonable, and I've had good luck with Kubota dealers (there are bad apples on both sides). Overall if you step back and look at the design of the two machines, you will see that some things are...

I contracted for a Kubota dealer for several years and we did end up doing axle pivot seals on some older 4wd machines. The L tractors were most famous for this. I did a few BX and B tractors but few compared to the L's. Regardless, these tractors are VERY reliable and usually the seal...

35 yr old Uconn graduate with MIS degree. Started tinkering on go carts and engines when I was about 7-8, was doing landscaping by the time I was in my early teens, worked 3 jobs when in high school (landscaping, dishwashing at a catering facility, and working at a bank doing check encoding)...

With 4wd, decent tires, and everything working as it should, I would guess that machine should be in the $5500-6500 range, plus the bush hog which should go for another $500ish..give or take. Keep in mind the HST models fetch a lot more money. You don't have an official kubota loader on there...

I think you're going to find a pretty big difference between the pyro temps and IR temps. My Duramax running at about 30psi of boost will hit over 1350 deg on the pyro....if you didn't change the fueling on the Kubota, I'm thinking you might be a little lean? Not sure how diesels work compared...
