    How many lb's do you have in your front castors? I pumped mine up around twelve psi and it like riding a bucking bronco. at the slightest little uneveness in the ground the whole machine starts to bounce like crazy. It is a JD 657 QuickTrak mower. Thanks...:)

    13 in front and 15 in back on my toro.

    I know guys who run 8 all round, but I'd be worried I'd peel off the rubber LOL!

    go with what your manufacturer says though as it does effect the machines abilities.

    I run 15 in my casters, on Great dane Super surfer ( same machine, basically) And I don't get beat down.. Are you trying to opperate it like the Duke boys? And I run 10 out back. these may not be real accurate I need to get a low pressure tire gauge...

    I gotta say too, these aren't the smoothest riding machines around. I found that if you "get into it" and use body english ( pretend you're riding a dirtbike or something ) it helps immensely with the ride. I am thinking about lowering the pressure to 12 in front and 8 out back though.. Experiment.
