couldnt tell you since i only have a few pines, and they are not near the lawn
i do have a rental place in town that has them for 38 bucks for 4 hours if you want to try one
(the also sell them but i dont know if they would put the rental towards the purchase price)
I have 11 pine trees in my yard and they make a mess every year so I'll buy a new one if it works. Love my trees but this old man is tired of a hand rake. lol
