One-Pass Site Preparation: Pulls Up Stones and Other Debris One-Pass Site Preparation: Pulls Up Stones and Other Debris

The Barber TURF RAKE is designed to remove stones and other debris from soils in a single pass before seeding and further site development. The rake is towed and powered by a tractor. It first levels the ground with a moldboard before drawing hundreds of spring tines set in offset rows over the surface. The debris collected then is deposited onto an elevated conveyor that passes the material to a hopper with a 3,800 lb capacity. The rake is able to handle stones from 1⁄2 in. to 4 in. It has a low center of gravity, wide design and flotation tires for stability during use. The rake can prepare as much as three acres of soil in an hour.
