Okay first off, I'm new to this site... Second, this is my first sub-compact tractor. I just recently purchased a B6100 at a local auction. I'm not sure of the year, I think they were made between '78-'84?? not sure though. Anyway, I brought this beast home and as I was doing my initial inspection of what I had purchased, I noticed there is a lot of play with the back wheels. I also noticed that the wheel seems to be attached to the shaft by a bolt... Is this normal? Are the wheels supposed to "wobble" on the shaft?? I'm sure once I get the answers for this, I will have many more to post! :D

I have always wanted a Kubota... and like I said earlier, I purchased this at an auction. I was told the seller was an original owner and that he only had it to remove snow from the driveway. The hour meter read 1100.4, has a front loader, and rear Ag tires size 7-16.

I just hope my purchase was a sound one, and I hope this lasts me for years to come.

Thanks to all who read this and comment!

I got the same experience with with wobbling on my newly bought B6001 (essentialy the same as B6100). There is a bolt and spring on the wheel hub that can be tightend. Se the picture below.
I could not get it tight enought so I slipped in a shim on the oposite side of the shaft. That stabilized the hub.
There is also another bolt that goes through the shaft and makes it possible to move the wheel in or out on the shaft.

Well, at least I don't feel that I am the only one with this problem :p Okay, so- If I tighten the bolt, that takes away the problem? Or should the wheel be tight against on the inside of the shaft, or out further? This just seems odd to me. Sorry for my way of explaining myself, I'm just not too familiar with these things yet (but I am learning!)

We all have to start learning when we get new machines. :eek:
Tightening the bolt will take care of the wobbling.
You can also move the wheel on the shaft. There are usualy three holes for the bolt. If you use the holes nearest to the ends you will get the widest and most stable position.

When I got my B7100, I thought it was twerking the first time I drove it on pavement- that rear end was all over the place. The hubs were very loose and when I tried tightening them, I found that they would not clamp any tighter because they were out of travel. In other words they needed more clearance in the area indicated by the yellow arrows in the pic. I cut some more clearance, threw away that lame spring, and replaced the pin with a bolt. (metric or SAE, I can't remember, but it was tighter than the pin) Tightened everything down & they haven't wiggled since.

Well, I went ahead and removed the back wheels. Ya know, the hub (on the B6100) is a rather poor design... however, it was probably good for it's time. Anyway, I tried to tighten the spring bolt to no avail, so I removed it. I also removed the through bolt. Is the "spring" bolt supposed to be able to tighten the clamp (on the inside of the hub) tight against the shaft? Well, mine doesn't move. I think this is the first time this back wheel has come off since applied from the factory... Back to the garage, thanks for your help!:D
