It is widely discussed that aeration can be a windfall for the bottom line but as I plan for fall I think it's the opposite. Sure I can charge 3x mowing price for aeration and then fert + seed on top of that. However, a walk behind aerating unit is much narrower and slower than a mower and if I do 2 passes that are slow and narrow I'll end up making less per hour than a simple mow. Then if I have already cut the grass short and over-seeded, then I'm not mowing for a couple weeks and lose money there. So unless I have a z-aerator (which I don't) where is the extra profit? Seems like it would be more profitable to not even suggest this package of services to customers which would be a moral dilemma because most lawns need it.
