New to Tractors so not sure if my hoe dropping down some while driving is normal. I mostly do trail work and some sections and road are a little bumpy. I ususaully travel in M and after about 10-15mins the hoe drops down some. I guess if i did not pull up on the left control it would drag the ground after 20-30mins? I usually reach back though and pull up on lever to bring back up. It has about 40hrs and had it back to the dealer for the problem. Dealer said nothing wrong or he could not duplicate??? Does it every time for me. I would think its the control valve or pistion. Looks like going to have to trouble shoot myself and wondering if i could switch hoses on control valve to see if pistion or control valve problem. Or is this sort of normal?
