Hi, I'm fairly new at using commercial equipment and would like some pointers. At work I mostly use an exmark Turf Tracer HP, 52" 17hp Kaw. I am finally able to so straight lines (it has a velkie) but am still having problems turning at the end of my row to start a new one. If I try to turn completely on a dime then I tear the grass, If I make wider turns then the grass doesn't tear but I am leaving uncut patches. I find myself making half a turn, backing up and completing my turn which is highly inefficient. Any pointers? Thanks!
