I want both a front and rear adjustment so that the angle of the bedknife is not changed over the range of height adjustment. With a fixed rear, the McLane has an overly aggressive angle when set to cut low and not enough when it is set to cut higher. I want it to cut well at all height ranges, including 2". Not everything I deal with is mowed down to fairway height. There are two grasses that must not be cut lower than 2". Setting the height of cut with the front and rear rollers will be done with the height adjustment bar with the screws and locknuts in them.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
