qd-16 14 #1 Posted November 1, 2010 When looking at parts diagrams of the trans. in my 1057, I notice differences in the differential where the pinions are. This looks different inside than my 856. Is the 1057/1257 trans. weaker than other wheel horse trans.? or just a different internal design? I wanted to use a snow plow on the 1057 this winter but didn't want to chance damaging it. Thanks for any info, Al. Share this post Link to post Share on other sites
sorekiwi 761 #2 Posted November 1, 2010 I think your 1057 has the 5058 Unidrive with the automotive style pinion gears in the differential? A lot of people have had problems with this style of differential, and they are generally regarded as the weaker of the differentials. On the other hand I have one in my 1276 (hydro) and I love it. I swear that tractor has more traction than any on my others, and that includes 4,8 and 10 pinion diffs. I plowed all last year with that tractor and never got stuck. Yes I spun wheels, but I never got stuck. I have another dead trans on the shelf with the same differential, and when I find my round 'tuit I'm gonna pull the diff out of it for one of the other tractors.
