I checked with Paul Chojnacky, our superintendent at Pasatiempo. According to Paul, it looks like Jim caught us in the midst of having mowed this particular pattern since March 15th and the stripes were "more than burnt in." We've been waiting for the new mowers to switch directions. However, not having the new mowers until the first of June, we actually went back to the half and half pattern earlier this week. Although our members and the public tend to like the bright stripes, we want to alter the mowing lines more often to not have them "so" burnt in and dramatic. Paul believes that it create better turf on the fairways anyway as the grass tends to lay down in the particular pattern if burning lines in. Switching the directions more often will prevent the grass from laying down and give us a better cut.
