Hi guys - I'm wondering whether I made a mistake in buying a John Deere D-130 tractor last fall??? I was not too happy with it's leaf pick-up results, during the fall, no matter what type of blade I put on it. Now I'm noticing that when I mow grass around a circular bordered edge, the grass is shorter on the outside cut compared to the inside height cut??? - I would say any where from a 1/2 to 1 inch difference. I even go slower on the radius to avoid a lean away from the circle - any suggestions?? I am very disapointed on the quality of lawn cut I get from this model tractor and deck!
