This was probably after you saying something like, "watch out for that soft ground over there, the truck will get stuck in it."
We had exactly the same thing on our Rayco 1635, we took the cable off and filled it up with wd40, good as gold after that.Haha... I now understand the whole tow behind big block monster grinder theory.....
Took about 90 minutes.... Big Euc butt is extremely dense wood... I dunno what it'd be like out there... at some points the wheel was just bouncing off the floor of the stump... also the whole time the throttle cable went bad so I was using vice grips... so I dont think I had full HP.
Blessed be the motherfunkers.
