Many of my customers have St Augustine grass and I've read that it's recommended you mow it at the heighest cut possible... This last month I've been mowing my personal residence at 6 inches for about a month and it looks ALOT better than my customers who have been getting mowed at 4 inches... Was hoping to raise the cut height for my custoemrs as well... problem is that I have been using my push mower on mine cutting at 6 inches and my Lesco will only go up to 4 inches... Anyone know if you can rig the lesco to cut higher? Do I need to upgrade my freakin mower? Any ideas?
