Hello All,We've been using a B5100D for the last year doing mowing around our small vineyard for the last year. (13 acres total, about 3 mowed). It's done a great job until last week, when it got stuck in reverse. We've done a great deal of jiggling and wiggling, andstanding around it staring, tsk tsk tsking and cussing.Apparently, that doesn't seem to help :)According to the manual, it looks like the only way to get to the shifter mechanism is by splitting offthe transmission case/clutch housing...requiring a hoist - and mechanical abilities beyond the feeble oneswe possess.Anyone got some tips or suggestions for us before we have to call in a pro? Thanks in advance for anything you may suggest. We're pretty strapped financially, so we'll try just about anything.Meg Mullett

I don't know if this will work in your situation but my old 8N got stuck betweem 1st and 3rd. I was able to remove the top cover to the transmission and pry the stuck parts free.
Good luck ....

If it's a synchromesh reverse, the shifting forks may have gotten out of coordination. My old '53 Chevy used to get stuck in second. You just had to pull on one of the linkage levers at the bottom of the steering column. I think it was Murf who mentioned awhile back that the same thing works for some kinds of tractors. The key would be finding some place that is accessible where the shifting forks can be operated individually. May not work, but it seems like a possibility and easier than splitting the tractor. ....

Try to put the lever back into reverse, than try by rocking to get the trans to release. I think you might have something worn in the shifter whether it is a shifting rail or fork it is hard to tell without dissasembly. ....

I don't have an diagram of that transmission, so I'm making an assumption that it is similar to most older gear type tractor transmissions. Which would make it similar to most old cars, trucks, etc. Any mechanically inclined person will recognise everything in there. The first thing the pro would do is to take off the top plate to the transmission. This is the plate with the gear shift lever mounted in it. This plate is usually mounted with about 8 bolts around its outer edge, and it is easy enough to get off. The entire shift lever will remain mounted in the plate as you lift it off and then can wiggle the levers freely or peer inside the transmission and even slide the gears back and forth on their shafts with your finger. With any luck, you will will be able to see what it is that is hanging it up. Some of these tractors that live outside get problems due to rainwater and dirt that enters past the shifter pivot, so be sure to clean the pivot well and look at the oil. Watery transmission oil looks like chocolate milk.
Some hints: After you remove the bolts, the top plate should lift straight up. This may require some force to separate the gasket. Reinstall it the same way as you wiggle the shifter levers to fit back into their places within the transmission. I don't believe there are any loose pieces or spring loaded devices there to "gothcha". The gasket may suffer when you take it apart, but some sealastic will repair it. There is no oil pressure on theat gasket, it is just a rain seal. You won't hurt anything by taking a look, Good luck.. ....

I don't know if this will apply to your machine or not. If your machine is 4WD and its engaged you might want to try raising the front wheels off the ground (use your loader if you got one) to unwind the transmission. It might shift out after you do this. I had trouble getting my TC40D out of 4WD. I mentioned it to the mechanic when he was out doing sevice on my tractor and he said the transmission was probably wound up. He suggested driving back and forth a few times to try and loosen it up. I found that lifting the front wheels off the ground with the loader works every time. ....
