How productive is this combination for residential lawn refurbishing mostly under ten thousand square feet each? What we have here in Northern Kentucky right now is extensive drought damage where there is hard pack, thatch and dead patches that need to be milled or turned I guess, and reseeded. All this, in as few steps as possible with no haulaway of thatch material. I have a Kanga DL 520. Would a Harley work on it OK? Also, if there is one available used or demo anyone has for sale please PM me.
