Simplicity 350 Transmission Locked

I recently reassembled the transmission on this tractor after many years without to much difficulty. However after mouting it back to the frame the tractor will not roll with the transmission in neutral. So I remove from the frame again. I find that one tire will roll backwards while the other rolls forwards so I suspect the differentail is ok (but not sure). The belt pulley input shaft at the top of the transmission will turn if in neutral but engage any gear an it is almost impossible to turn.

If I open the tranny up again what am I looking for or could it still be the differential? Thanks.
 
Check to make sure shift fork is in the right place.

What you describe about one wheel turning one way and the other the other direction is normal when the transmission is in gear. The transmission is not in nuetral.
 
You don"t say which transmission, but if its like a Peerless or Foote, I bet if you loosen the case screws it will turn freely. you probably have a spacer out of place, a bearing upside down, or something like that.
 
It is a 1966 Montgomery Wards Squire 10 which I think is a Simplicity model 990350 tractor. I don't know how to tell what transmission is installed.
 
As t.r.k. indicated, many of those transmissions have bushing type bearings, (as compared to needle or ball bearings). These have a small tab on them which fits in a groove in the case to keep them from rotating. There is a possibility that one of these is out of place and when the case is tightened it puts the shaft to bind. Just a thought.
 
Goto link below,click on simplicity logo,enter 990350 on left side of pg for mod#,look at transmission group assembly drawing/parts list,confirm with drawing that parts in trans reassembled in correct order,also check shaft keys AF & CU for wear/damage which could cause trans to engage 2 gear speeds at same time locking up trans when shifted from netural.
