    I have a almost new JD 757 - 2007 with 25 hours. After using mower for about 1.5 hours - the left side becomes sluggish and starting vibrating. This is at full throttle. Most noticiable on a hill.

    I took JD to dealer - problem could not be dulipicated due to being cold. Mechanic wanted to take it home and cut his grass for the weekend. I declined his offer. I plan on taking to another dealer.

    Any ideas before taking to second dealer? Any purge valves (maybe air in lines)

    Thanks for your help,. David

    My 717 did this a little when new. Now it's smooth as can be. I just attributed it to breaking in.

    I thought the same thing - however it's gotten to the point the left side will not pull.

    Do the pumps on the Deeres have relief valves for transporting when not running? If so, could a valve have loosened up?

    I'm just guessing but I'll bet some more knowledgeable Deere guys will chime in soon.
