I am going to be touching up portions of the lawn and am not quite certain of the proper piece of equipment for the job. There is exisitng grass growth, but holes, ruts, high spots etc. that I would like to eliminate. I have a 32 hp tractor with 3 point hitch to drive whatever is best. Is this a job for a tiller, harley rake, power rake or other? I don't expect to need to go any further than 6 inches down at any point to level areas.
