I just read your other post. sounds like you have the manual trans. there is a great repair manual in our manuals section. go to manuals, click on transmissions, then on page 2 there is a great Techumseh technitians manual, the 2 manuals below it (peerless 2300 series) are the same as this one but this is even better. sounds like something broke or came loose on the shifter fork. If fork is moving then you might have snapped the input shaft (worse case) we just had a member do that to one of those trans.But download the book as it has great info on how to rebuild and also has trouble shooting. Good luck!

I had a simular problem with my toyota truck. Turns out it was the top seal that had deteriated and was falling down inside the shift mechanism. Not sure if this is you, but I hope it something simple like that. Any pictures of the Jake? Bet it's a dandy!

You might just find something simple if you remove the 3 screws from the shifter cap. might just be the shifter broke off. Good luck.

Make sure you don't have a sheared key or sheared splines on one of your axles. If one of them shears, then it'll see as though you can't find a gear, when in fact you are, but the spiders in the diff are just spinning the stripped axle. I'm not familiar with your tractor, so this is just something to check.

I agree with olcowhand especially if you were doing some heavy pushing. Real easy to check by just looking at the axle shafts while the tractor is running and in gear.

My guess would be check the pulley that connects to the motor drive belt. The key in that could of sheered and the pulley could be just spinning on the shaft and not turing the trans. Or with all of the torque against the shift fork, you could of broke the bottom part of the shift lever off.

Good luck getting it sorted out. It looks like you are getting lots of help here. The manual will be a big help in finding out what's up. I hope it's something simple because it's still a bit cold to be working outside- at least here it is.
