New to me 2 months ago 2018 KX71-3 I have spent a bunch of time getting rid of rust induced stiction so all the controls are very free moving. This has helped a bunch but the main track controls are still giving me problems. It feels like they move 3 inches and do nothing and then there is 1/2" where it goes from nothing to full speed. It is especially bad when I have the bucket on the opposite end from the blade. Of course you need to pull the levers back to go forward. It moves, my body moves backward, and I jerk the levers. I try to run the levers one handed while holding my body still w/ my other hand on the cross bar but it only helps a little and sometimes not at all. Can any of you offer me some tips please?
