    I'm looking forwards to your results and further experimenting with these blades. There's def a big difference in the lift!

    Wow! What a difference. I look foward to your results.

    Also since your 272 has the 400 series frame which isolators are missing? All, foot, seat, or engine?

    Just the ones under the seat. The foot platform definitely has them and I assume the engine does too but I haven't looked for them.

    I will be picking up a 460 Tuesday evening for an all day demo Wednesday and Thursday. I will be sure to let you gentleman know how it goes. Any set up tips?

    Nice! I like the ride best with the air seat aired up 1-2". Its going to depend on personal preference and your weight. Baffles will come in all the way up position. You will get more lift as you lower them. A good all around position is 1" down but again it will depend on your conditions. In really wet thick grass I like the baffles off which gives you a nice fan shaped discharge and less build up under the deck. I like 12 psi in the rear tires. These tips should give you the great ride, hillside ability and cut quality I get as it seems we are mowing similar grasses in mountainous terrain.

    Outstanding! Thanks for the knowledge my friend, I really do appreciate it.

    If you don't have time to level the deck, though, just leave the tires at the stock pressure so you can see how well the deck does first and then lower pressures to get a feel for the ride

    Just cleaned out the deck (holy soaking wet crabgrass this morning batman! We finished up already for the week at our 7 big lawns this morning) and sharpened the blades (its been 50 hours with out sharpening) and I also lowered the baffles all the way to try that setting out next week. I have not had them all the way down yet so lets see how that goes!

    Well, these blades with baffles installed generate a super crisp, carpet quality cut even up at 4-5 inches but the discharge velocity is so strong up front that the low pressure area UNDER the front lip of the baffle is directing a small stream of clippings (maybe 15%) at downward angle and laying them right in the tire track of the previous pass.

    Removing the baffles stops this but the clippings come out larger. Hopefully there will be a position that works with the baffle - even if we have to weld on an extension so the outer edge of the baffle lip matches the one on the pro stance deck.

    This is all great info, and I appreciate you taking the time to keep us updated on how it's going. This is with no spacer, is that right? I wonder if having the cutting edge back down that 1/4" would make a difference? We all know that even minor changes can make huge differences in performance with a Z's deck. Maybe the cutting edge back down closer to the bottom of the skirting would make a difference, but I understand your reasoning for not wanting to do it all the time. If you get the chance to experiment with that though, I'd sure be interested in hearing the results.
