After checking that the PTO worked I tried something else. I used the FEL to pull the tractor up a hill on my trail. From there the tractor would roll backwards if I let off the brake while in neutral. But if I put the tractor in 1st it held it’s position on the hill without the brake applied. I think this rules out an issue with the shifter.
B7100 stalls on clutch release won’t roll in neutral.

This evening I went down to pull the shifter/trans cover off again just to see if I could see anything obviously wrong. There wasn’t anything glaringly broken from what I could see. I put it back on aligning the shift forks as before and started it up. I still had no forward or reverse in low range. But I had not tried high range before so I thought I would give it a shot. As it turned out I had forward/1st gear drive in high range and was able to drive it up out of my field.
I’m guessing some spur gear got stripped for the low range gear? I haven’t been able to locate the correct repair manual on Kubotabooks.com for my non-HST B7100. Can anyone point me in the right direction?

On the HST models, there is a neutral position between low and high range. Any chance you were in neutral?
I think that may have been it. The linkage/lever isn’t particularly tight. The day it happened I didn’t try high range. Doing that was an afterthought. It’s possible it just popped out of low or that I bumped the lever.
It still gets caught between 1st and reverse some times. Particularly when I need to shift on a hill or while under some other load. But other than that it has been working well.

I've never had a tractor transmission apart, so I'm not certain there are parallels. However, I've worked on many motorcycle transmissions and it is critical that the gears are properly spaced (using thin washer-like shims) and the shift forks are not bent out of shape. I suspect something similar is true in your case -- there is excessive play somewhere. It should not be physically possible to engage two gears at the same time. You mentioned taking the transmission to your local dealer for service -- I suspect he didn't get something quite right.

I will assure you.... it's very possible. But, something isn't right causing it.
I posted the same info a week ago in post #15.... At least you're not fighting winter creeping in.

Please don't misunderstand what I said -- I don't doubt that it is happening, I am saying that it should be assembled such as to prevent it. Perhaps a shift fork is bent, or perhaps there is excessive clearance somewhere. I'd also look for signs of wear like rounding, which can cause a shift fork to flex just enough to pop out when under load. A common problem with boats and motorcycles that can sometimes be solved by refacing with a slight back-slope such that the pieces are drawn together under load instead of forced apart.
But again, I have no experience with this or any other tractor transmission, so I cannot offer specific advice.
