on that field, all be it, not the deepest mainline, but usually at least that is a bare minimum I have had to go in some areas due to obstructions beyond my helping, that however should not have been the case in that location. ok, that is some deep aeration. looks to be the kind that is deeper without cores am I right? usually vibration action....
all is fair in love and grass!
Man, it smells like sheet, do you smell that!!
