I picked up the PL855 today to demo. We got a tiny bit of moisture overnight but things are still bone dry. I used it on 7 yards and was able to pull decent plugs. This machine is totally different to operate than any other aerator I have used. The controls take a little to get used to and I realized quickly that you get much better results if you don't go full speed with the forward lever but keep the tines going full speed. If the ground is too hard it just bounces off and you get tiny plugs, but in most spots I was able to get about 2 inch plugs and got a LOT of them. The ground was pretty hard and I'm hoping I can get it to pull a little bit deeper in ideal conditions. Also, this thing sure as hell doesn't seem like it's 30" wide. I didn't measure it before brought my equipment back to the shop today, but it only felt like it was about 23-25"(aerating path). Also, any advice on flipping 180 degree turns without raising the tines? I could kind of do it but I felt like I was putting torque on the tines. Any general tips or techniques to help when using it?
