We have a great older Brinly-Hardy Moldboard plow for use in lawn and garden with a garden tractor or ATV. These are tough and really bust the sod.
Brinley knows plows. In fact, Brinley has been manufacturing plows for over 173 years. Whether you are breaking new ground for a garden or landscaping, The Brinley moldboard Plow is the right tool for the project. The heavy duty steel Coulter blade slices through sod & soil while the plow effortlessly digs the furrow & the moldboard turns over the old vegetation & sod to make way for new planting. All of which can be done easily from the seat of a garden tractor.
These sell new but un-assembled for $350 plus tax on Amazon today:
