Just an update for everyone. After putting about 8 hrs on the tractor, my jerky loader problem seems to have gone away.
The other day it was about 40 deg. and I had to clear snow that came off the metal roof on the shop, it worked fine. Today we had about 10" of snow and it is only 18, worked with no problem.
So I am going to continue using it and if it comes back I will take to the dealer. Otherwise when it hits the 50 hrs I am going to change to Low Vis Hygard.
