As far as the drag issue, let's think about it for a minute. If the deck is pitched 1/4" front to rear as most guys seem to do, that's over the length of an approximately 21" blade. That's a pretty shallow angle, and you can bet your hinnie that the grass blades will still be dragging the blade's bottom surface. Think about all the turbulence under the deck surrounding the grass blades as they are cut. Too, when the blades actually make contact with the grass blades they tend to bend over slightly before being cut off, which means that they spring back up enough in all probability to drag the bottom of that shallow pitched blade.
Yea I'd agree with you. I got plenty of power which I'm sure I'm paying for with the 31 Kaw. So power is not an issue in my case but lift seems to be. I check my blade balance and deck height/pitch new. The MB blades were quite close but I only use a cone balancer. The deck they recommend a pitch of only 1/8" which is super minimal. I may try pitching it more to see if it effects the stragglers I'm seeing. But I would think more pitch would also = less vacuum so I may be going in the wrong direction.
