Well.... not many of these things are out there, so the amount of people that can attest to how well they work are going to be few. But lets look at it from a comparison standpoint. The front blade hangs a couple feet in front of the tractor. Any movement on the rear tires is magnified in the front proportional to how far the blade is from the rear tire and the pivot point (front axle). A one inch hole that the rear tires dip into may be a one or more inch rise on the front. Same is true with a rear mounted blade. Even though the wheelbase of the tractor is short, with a center grader blade any movement on the wheels would be reduced by half, as opposed to equal or a tad more. So.... a one inch hole now affects the blade by only 1/2". How fast can it be adjusted?...... As fast as you can move the lever. It's attached to the same lift as any other attachment.
