I have a Ryan Mattaway oversseeder that can be used as a slit aerator as well. It is self propelled and has the Kohler engine. Everything works perfectly and is an awesome machine for installing new lawns or overseeding existing lawns. Absolutely needs nothing and is ready for work. Item can be shipped and would approx be $300 to be put on a pallet and sent freight. Item may also be picked up locally on Bowling Green, KY.
