Even though many people have said it could not be done, people won't care etc.....I have marketed my aerations these last 2 years as being a greater net benefit since I run a Plugr 850HD that has a very dense plug pattern. The most common response I get is "wow that is noticeably more plugs than the last guy who aerated". I believe only the Ryan 28 tricycle unit pulls more plugs per square foot than the Plugr 800, 850 & 855. Even that I'm not 100% sure. I have never used the Ryan 28 or even seen a plug print pattern nor have I ever seen one in service in my area. If I could rent a Ryan 28 just to try it out I would. My Lawn Solutions WB ships out today and I also need to get my hangers and flyers finalized this week. Correct me if I'm wrong the Plugr 800, 850 and the new 855 have one the densest patterns in the industry. IMO it makes little sense to run one of these unless you are claiming more plugs..... correct? Reason is these machines wear out tines very quickly and the tines are not cheap. A set of 8 is well over $120 and they only last maybe 50-60 aeration in the rocky soil here. With all that said why deliver more plugs and NOT brag it up and or charge more money? *** Recent development....I just bought a Lawn Solutions WB and I'm excited to get this machine for the ease of use from what I can tell from video and user reports. I'm also very confident it will pull deeper plugs than the Plugr The best I can tell the Lawn Solution WB pulls possibly slightly more per square foot than other rolling tine types. Not 100% sure about this. All things being equal it makes little sense to burn up Plugr tines at a rapid rate with the wear and tear of the bouncing machine on our rocky soil here and not switch over to Lawn Solution machine as the main working unit. So should I charge more for the Plugr aeration vs. rolling tine aeration of the Lawn Solution machine? Any input from aeration veterans much appreciated!
