Nice pics man.....you have some nice equipment. Do you have any problems dethatching in the spring with crab grass. In my turfgrass management courses they taught us to never dethatch in the spring because you are increasing the chances of crab grass seeds pollinating. They told us to always dethatch in the fall.....maybe its different in michigan. Since being taught this I have always tried steering customers away from spring dethatch and do it when we do the fall clean-ups etc. Everything looks nice though....keep up the good work and make some money this year!
