HST Survey

TPS · Oct 28, 2008

Hello Fellas,
I have done some reading at another site and saw some complaints about the Kubota HST's not holding up. They are about 5 to 1 claiming problems with the HST system. I did a lot of research about the BX before I bought one and never encountered anyone including my dealer that ever had a major problem with them. The problems noted were showing up at around 2-300 hrs sometimes less and were major for the most part. Most of the folks at stated they thought it was because of the heat the HST generates. I have 145 hrs on mine no problems, use SUDT and have changed and will change SUDT and filter before the hrs in the manual. My question is how are your HST's holding up? Any problems and what should we all do to insure we don't have problems?Thanks,
TPS

The HST on my Kubota B7100 has been going for 3000 hours with no problems other than a branch wedging itself in and bending some of the linkage system.

I have owned 4 Kubota tractors with HST, and have never experienced a problem with that feature.

Thre are are tens of thousands of KUBOTA HST Tractors on here.
So my question is
How many complaints like that have you read here?

150+ hours in high heat pasture mowing as well as other high heat situations and not even a squeak.

630+ hours, no problems. I love it... makes the tractor safer, IMHO. I've been watching TBN for several years, can't recall ever a thread about a true HST problem. There have been several about how it works, what range to use, typical noise, what kind of fluid to use and how often to change, relief valve pressure.

I believe if there were an HST problem, it would have been candidly reported and discussed here. I haven't seen it. I would much rather have HST than any other I've ever had on a tractor.

Thanks for the posts guys. Brown, I have not read any, but also have not seen the question asked specific to this either. Anyway do you have any feed back on your three machines as to problems fluids etc.? The site with the problems was a Kubota tractor discussion board. I will try to get a link and let you read them yourself and see what you think. Glad to hear you guys have had no problems either.

PS Here is the link. I asked the question because of some complaints I had read there and see the answers under HST problems and see what you think.

Although I have never experienced problems with the HST system itself, the HST feature does require a bit of attention from time to time. In addition to the scheduled oil and filter changes here are two examples. The HST pedal may fail to move properly because the owner has forgotten to grease the fitting. Another example, is the fact that the tractor may continue to move on a level surface when the HST pedal has returned to the neutral position; that is the result of normal wear, and can be easily remedied by following the a simple adjustment procedure called "Adjusting Neutral" in the WSM.
