I have two Troybuilt "horse" rototillers. They appear to be identical. Kohler makes an engine specifically for these old rototillers. They are both compete, but not running. Excellent restoration projects. I just moved both across the yard, the gearbox works good on both. They shifted into neural and rolled easily, no weird noises.
Asking $150/each.
I also have a Troybuilt "pony". Newer and smaller than the others. It is equipped with an electric starter. Asking $150.
Prices are firm.
Located in Palominas / Hereford. Hwy 92, just west of the river.
