We typically mow the fairways in a circular pattern going from the tee to the green and vise versa. This is a real time saver to stay ahead of play. The downside is that the turf is constantly being pushed in the same direction, flattening out, and mechanically being trained to grow more laterally. We were noticing that the club head was getting caught and lifting up laterally growing turf. By mowing different directions we are promoting the turf to grow more vertically. With doing this we have had some scalping in the fairways, which we assumed would happen. This should heal up very soon and the end result be better ball lie and playability.
A new direction of mowing creates excessive amounts of grass.
