The bush hogging yesterday was on a hot, dry day and the material didn't stick together as much. It was just interesting to see the difference in discharge velocity while moving at a snail's pace so I could really concentrate on it. We were mowing 4-6 ft tall grass and reeds in some places that hadn't been touched since fall 2012 so I was happy the deck was able to handle the little bit of mowing around the edges where we didn't want to take the takeuchi and ambusher. So again, just noting that the xf1 deck with high lifts and 60 inch cutting width has a better discharge than the xf2 with standard blades, baffles removed, and 72 inch cutting width.
I just finished mowing some areas with the XR-7, when I came back down my drive I turned the deck on to see the difference in discharge air speed while blowing a little trash off the asphalt. The XR-7 I've never considered very good when blowing off asphalt, mediocre at best, but when comparing to the discharge velocity of the 472 it was much more powerful.
I can fully understand the grass falling out of the discharge opening, the 472 virtually had no discharge velocity at all, to the point it will blow some grass off the pavement, but leave more than it moves if the clippings are scattered and thin.
This is something that definitely needs to be addressed, the only good clean cut I saw with the 472 while producing a reasonable discharge was in somewhat drier grass while cutting at 2.75" on the dial-a-height, but when measuring the cutting edge of the blade to concrete, it was actually 1/4" lower.
These mowers should go to the owner or person demoing the mower ready to cut grass to the best of its ability. You should not need to figure out what blades you need to install, or whether you do need, or don't need the baffle. This can cause a lot of sales to be lost, many people have not had experience playing with these changes, and for a mower to be demoed new with the results I saw, most people want say anything, they will just try another mower.
