| As far as i know you could get the 12 speed twin disc Powershift transmission for the 60/70 series 4WD tractors and the 9000 series,but they are hard to find,especially on the smaller models.With the introducion of the 9020 series 4WD tractors DEERE offered their own 18 Speed Powershift transmission,which should be more reliable,offers more gears and is faster(up to 25 mph),and there are more used units you can find,even smaller ones.The 9120 offers 20hp more than the 9100. | |
