For you guys with new machines-

Set the front to rear pitch on the blades themselves when pointing straight front to rear at 3/8" with no one in the operators seat. If you can get someone your approx weight to sit on it while you set pitch, set it at 1/4". They tend to come from the factory at about 1/8" - 3/16" pitch, and not always correct from side to side. The cut will be better when pitched correctly, and the stripes will show better as well. I've played with all this stuff on several JD's now ALOT, and have it down pretty well by now. Set the pitch over smooth concrete. Even minor birdbath dips or humps can throw the pitch off. I use JD's deck leveling gauge, and have for about 10 years now. It makes setting pitch easy peasy.

Set your rear tires pressure to 12 psi before pitching the deck. 10 works, but is kinda soft and flexes too much on side hill mowing. The manual recommends 12, and there's a good reason for it.
