    With regard to the air flow, would you think the centre blade being pitched 1/4" forward from the other blades would be causing this kind or air flow issue.

    green-
    without being there to see what all is going on in person, it's really hard to say anything accurately, but I would think having one blade off that far from the other two would cause all sorts of problems. I just can't say if a turbulence issue would be one of them or not.

    I know Im harping on, but I just think that shouldn't have a pitch on it like that & just happens to be QOC issues, could be a coincidence & both are separate issues. Or it could very well be that one problem is causing the other.

    id be spending my time on rectifying that before trying other time consuming things, then you can rule it out & plus get it back to the way it should be. If there did happen to be a pitch on the pulley, then eventually it will wear the belt.

    edit: Other tips from mick-ridin are great and better than I can offer. Im not discounting that in any way! Just think since you've found a problem, you might as well attempt to fix that, unless u know for sure it couldn't be causing the problem, which I don't think we do.

    I will check the pulley for level as soon as I can find my level. I would need to check at two relative points I would think. For instance, place level on deck surface and then on pulley in order to see if there are differences between the two.

    You have solved the puzzle, and I posted this time and time again, the XR-7 cuts great at 3" or below, and does exactly what you are seeing at 3 1/2" or above.

    This is very simple to figure out, and definitely not something new. Find some decent grass and drop the cutting height below 3" and watch your problem disappear, raise the deck back to 3 1/2" and watch the problem reappear. There is nothing wrong with your mower, it's the nature of the beast.

    I would take bets that's the problem, give it a try tomorrow.

    You can't get rain, and it has rained me out again today, we are 10" above normal. We've had entirely too much rain, I can't remember in my 40 yrs of farming ever seeing my corn look this bad.

    See it hasn't rained in a while, but our corn around here is doing well! Same with beans. I drove past a bean field today with fully developed leaves already. Probly 8-10" tall already.

    I was just looking at a 2012 66" super z and I had an idea. Puppy, do you have any clue if the 66" vx4 will bolt up to a 2010 frame? The mounting points look similar.

    Hmm, even if the pulley ended up being level, I would still be wanting to rectify the pitch on that middle blade. I dunno how & I do understand how much of a pita it may be. But a 1/4" pitch on the centre blade is standing out like dogs balls to me as a problem.
