I have recently bought a used John Deere 55 Combine. I got it home ok but tried to use it the other day and it would not move once it was in gear. I pulled it up to my shop to work on it and while pulling it up the road I also lost all the breaks and the clutch. I"m not sure what is wrong with it I hope that this can be fixed at a reasonable price. If anyone has any solutions or suggestions please post them. Thanks!

Stripped drive shaft coupler. The brakes are on the tranny so when a coupler strips you've lost all control to the final drive. Drive out the roll pin in the middle of the coupler on both ends of the shaft, slide the couplers in on the shaft and remove shaft. You'll have to investigate to find out what side it is. Seems strange that you lost all brakes. Usually when you strip a coupler only one side strips out at a time. Jim

10-4. It runs between the tranny and the final drive. I was going to suggest to put it in gear, let the clutch out and then step on each brake individually to see if one of the brakes makes the combine move forward but you say you lost both brakes so that idea's out. If it is a driveshaft have someone sit in the combine and put it in gear and let the clutch out. Then look at the driveshafts and see if one is just sitting there turning. If both of them aren't turning then look closely at the stub shaft coming out of the brake housing and going into the coupler. I'm not sure if you can see it or if the coupler is too close to the brake drum to allow you to see it. The brakes are manually operated brakes that are on each side of the tranny so if you lose the driveshaft or if a gear gives out in the final drive, you will not have any control with the brake on that side. The brakes never were too good on those old combines anyway, at least they weren't much good on the 105. If the shafts are OK, then you have bad brakes and something else in the power train is bad too. Jim
By lost the clutch do you mean it won't engage? Or will it not disengage? The shaft that goes in to the fork on the throwout bearing broke on ours. It was holding just enough to slow the combine a bit but the brakes still wouldn't hold it back. It was fun trying to get in the barn to work on without ramming into something or driving out the barn wall.
