I recently acquired a used JD 447 BH mounted on my 3320. I'm a novice operator but things are going well after a few hours in the seat. One issue is the up speed on the boom. It is very difficult to feather. I've often gently pulled the lever back only to have the boom slam back towards me and just about send me over the hood of the tractor. All other operations on the BH are smooth and easily feathered. Is there an adjustment to make the boom up a little less sensitive?
