Good day to all.I need some help figuring out how to keep my 3PH from bleeding down when I'm using my bush hog. When I raise it completely, it very slowly bleeds back down a few inches, then recharges or lifts back up and the process starts over again. It only takes about 30 to 45 seconds for this to do a complete cycle. Very annoying and it sorta jerks the tractor alittle when it recycles. A few of my friends, none of us being mechanics, say, just take it back to the dealer. I purchased it new in July of '07.It's an '06 3720 John Deere. I have a 295 Bush Hog on it that weighs 910 lbs, according to the manual. It doesn't keep us from using it but, it is annoying and can think of nothing good that could become of it. Any and all comments on how to correct this will be greatly appreciated. I know I should read up on it more through my manuals but....., I'm trying to help the forum by posting a question, and besides. I like to hear different points of views, not just the printed variety. Thanks, Tom
