hey there. i was just asked today to give a price for installing a new lawn at a customer's house. about an acre or so of lawn to be put in from seed. there is a started lawn there now, just beginning to grow. weeds n' seeds is what the builders call it. i looked around and there are some big loose roots as well as a good amount of smaller rocks and some gravel as well to be picked up before good turf establishment can take place. now as we all know this can be done by hand, a lot better than by machine. however to go and rake up all of this stuff by hand would take a few guys a good couple of days. so what i want to know is this. i have access to a harley rake on a skid steer, and i have access also to a york rake on a large kubota tractor. i was thinking about incorporating some sweet peet into this lawn as well before establishment. so what is a better tool for picking up rocks? i have used a york rake before and that is good, but i think it may leave some stuff. i saw a harley rake once up close, but have never seen the job it does. so what form of aparatus would you fellas use for this kind of work?
