I recently picked up a 1054-01, along with some attachments and a 600 parts machine. The 600 is not running (and won't be any time soon) but has a good transmission. The 1054 is running (with a Honda swapped into it) but has some stripped gears. I have the proper, original Wisconsin engine for the 1054 and my plan is to get it back to reasonably original condition. I hope to get the 600 up and running some day as well. In the meantime, I am wondering if the 600 transmission will bolt up to the 1054 frame and driveshaft, so I have a functional tractor as a backup to my other 1054. I am aware that I will lose the high/low feature doing this, but the high range gear is one of the ones that is stripped in the 1054-01 now and I can manage without it for now.
