Jim @ TURF Magazine here. Im looking for someone to field test a new dethatcher made by MacKissic. They are hoping somewhere in PA, but could accommodate surrounding states. They are especially interested it having it tested on a lawn with sprinkler heads. As usual, if you have interest it involves using the equipment for a couple of weeks and writing up notes on what you observe on the job. We pay for the field test, not them. If youre interested, please email me at email@example.com Thanks!
