  • 39 9n "posi-trac" rear end all of a sudden.. PLEASE HELP!!
  • I've got a 39 9n that I was using to spread a wood chip pile earlier and all of a sudden it started scooting the front tires instead of steering even with me standing on either brake (I'm 286lbs).. so then I backed up to a big log and let out on the clutch and both tires spin together. I've tried to "brake-steer" left and right forward and backwards and both back tires run together just like it has a differential lock. Has anyone ever seen this happen or have any advice? TIA

  • Sounds like something has broke in the differential maybe a side or planetary gear and has locked the differential, you can remove the differential by removing the right axle housing (I think it's the right side) but be careful because the center section can fall out.

  • Jack it up and rotate wheels in & out of gear & you will figure it out.
