i just bought this aerator for 200 bucks from my neighbor, i used it today on my own lawn and i think it works great. has anyone else used this john deere brand and what do u think. i am definately going to beef up the tires and axles, after i put weight on top they start to canter inwards. also i use the motor for hooking up the tines and running them at about 16000 rmp. this really get the dirt a flyin.
