I don't know if its the lift arm. I could not budge the adjustment knob.
We are getting pounded by snow maybe 10 inches now. They say we could get 14 now. The snow plow worked good and the 1650 really grizzled it's way through the snow like butter. No tire chains and I did get stuck a few times. She needs some good TLC but works good so far.

While getting off once to get unstuck I accidently broke one of the rear lights when I pushed the tractor. But it got it to turn on. As both were not working. lol
