I am new to the Aerating part of the biz and I have a few questions I'm hoping to have answered. Most of my customers that I will target for Aerationg are properties of approximately 1 acre, or just slightly less. My ZTR goes everywhere that I would aerate. I dont own an aerator, nor do I care to at this stage, so I'll be renting. How long does it take for cores to break down? Will I need to skip a week of mowing because of the cores in the lawn? I can rent a tow-behind unit (core-type, 40-48", don't know the brand) or a much smaller, walk-behind unit (20-24"??) Obviously, because of the size of the props., I think the tow-behind would be better suited and more profitable (I can pull it with my ZTR, right??) What do you think?? Tow behind, or walk? Should I assume that aerating with a tow-behind (1 pass) should take as long as mowing same prop.? Less? More?? With a walk-behind unit, how fast will I be able to move? Will I be there all day to do an acre?? What do I do in the areas that I cannot aerate? For example, one property has a cable line buried shallow that cuts right across the side lawn. I was thinking of using a manual dethatching rake along that to loosen the top a bit. I will be overseeding this property. Which brings me to my next question....... How much seed will I need per, say, 1k sq.ft.? I will probably go with a rye/fescue blend, as that will blend best with most of these properties. Sorry for the long post.............. Thanks for any help, I really appreciate it!!!
