with all this talk about discs and rototillers, people with small tractors should know that there are real discs out there that actually do a great job. I am super fired up on this 4 foot, pull behind, offset bad dog, because it has transport wheels,brand new blades, really cuts deep, and has scrapers. It is supposed to have a hydraulic cylinder, but it started to bend the frame, so now it is Okie style with a chain and binder to control the wheels.
