A few years ago I bought a WD with a loader on it for 600 bucks. I went through it and put a new water pump on it, new manifold studs, rebuilt the carb, gave it a good tune up, re-plumbed the loader hydraulics so that both cylinders actually lifted instead of just one (previous owner had no clue what he was doing), and rebuilt the seat bushings and spring and I had a really good running WD with a trip bucket loader. Earlier this year I had gotten it out of the barn and cleaned it up and put fresh gas in it and was going to take it for a shake down drive before I started using it. I was headed down the road in road gear, had to throttle back for a 90 degree corner, and being the stupid kid at heart that I am, as soon as it was headed straight again I dumped it full throttle to hear the motor lug. Motor sounded great, but the rear end went POP and the tractor skidded to a halt. It wouldn't pull itself going forward any more. It just made popping noises and shook. I was in the middle of the road (rock back road so not that bad) so I tried reverse and it moved just fine in reverse. None of the forward gears would work though. I backed it into a hay field and walked home to get the truck and trailer. I winched it on my trailer and hauled it home. That was 5 months ago and I haven't looked at it sense.

I am needing to wait for awhile to build up some spare cash to keep working on my drag car, so in the meantime I am going to try and get the WD repaired. I did manage to buy a stripped down WD for parts so I think I have what I need. Any idea what might be broken and where I need to start? I know I need to pull the dif-cover and see what it looks like inside, but I was hoping there was a weak link that some WD guys knew about that would aim me in the right direction once I got inside.

You may have broken one gear but that part fell in to the other (forward stack of gears, leaving you with only reverse). You will have to tear into the transmission to get a better diagnosis. You most likely will have to split the tractor in half, just do it safely. You should look for the service/technical manual from one of the vintage tractor sites to help you out.

Perhaps a rear brake shoe came loose,and is only jamming up in forward motion ?...
I had a truck do that once when the hold down hardware pins rusted away and let one brake shoe jam up going forward..(but the truck did still want to move,but the other rear tire would start spinning if you gave it enough throttle!)....
It could be the differential on your tractor had a part fail and its jamming only in one direction..
Unfortunately tearing the transmission and rear end apart may be the only way to find out whats wrong..
