Hello all, I'm new to this forum, so if this post is misplaced, I apologize.
Recently I've purchased a well used Kubota b7100hst made in 1983, and among other things that could use a little work, I have some questions about the hydrostatic transmission. Please forgive my pathetic knowledge of the tractor, its the first good sized tractor I have owned. Now, when starting the tractor, I obviously am required to press the hydro disengage pedal on the left. But when the tractor is running, and I release the pedal, without touching the forward/reverse pedal on the right the tractor creeps forward, sometimes immediately and noticably, sometimes just barely. Is this normal? If it isn't, how easy is it to fix?
Also, I have a question about the 4wd lever. I assume its the larger, more accessible lever on the right. I've noticed there are three settings, the middle of which seems to be some sort of neutral for the tractor, as it doesn't move in this setting. I haven't had a chance to really get down and test each setting, so could one of you perhaps tell me which setting is 4wd, and which is 2wd? Thanks!
Thanks for all your help, I really appreciate it!

On a tractor when creep issues come up there might be several things that we have seen cause it. The adjustment of it is one, but yours seems to change so the next area that I'd go to would be a fluid and filter change to the recommended oil and filter.
You stated that it varies, it is probably doing it with temperature change and that would tell me it would be with possibly be the oil. ....

As tractors go, it's not all that old, and you should have no trouble buying a service manual for it. ....

I have a B2710 and there is no neutral to the 4 wheel 2 wheel shift on mine. It is either in 2 or 4 wheel. On mine the shifter is on the right side and lower level right below lift lever if memory is correct. ....
