Good recommendation on checking the rotation of your blades. I recall some earlier discussion about this and how, I think, PT changed their set-up. My '04 48" mower (sold) and my '05 60" mower both spin CCW looking from the top down (and obviously CW looking from the bottom). The grass gets shot out to the operator's LEFT side and rear. Clippings always accumulate between left front wheel and wheel well sidewall.
I'm sure you are already aware, and I don't want to insult anyone's intelligence....once the direction of blade rotation is confirmed, one then needs to check to be ceratin that the leading edges of all the blades are indeed the cutting edges. It's like the glass half full/empty, i.e., is the rotation direction incorrect, or were the blades somehow factory installed ba**ackwards??
Like MR and others, I love the cut of the PT finish mowers, and the neighbors do, too. I can cut 3 Ac in a different wavy pattern each time, and have it looking striped like a golf course fairway.
Don't give up on it just yet. /forums/images/graemlins/grin.gif
