I am looking at purchasing a Dethatcher. We have been performing quite a few lawn renovations of late, and might look into buying instead of renting. We have suffered quite a bit of drought stress in the area the last couple years, and are in need of repairing stressed areas in a lawn. We are not replacing the entire lawn, but brown bare areas throughout the turf. Does anyone have any recommendations for equipment that can be purchased or manufacturer? Also, does anyone have used equipment like this they are looking to get rid of? Thanks in advance.
