An important application for this tiller with rear roller is to bury wood chips by tilling 2 to 3 inches deep. The roller then slightly compacts and smooths out the orchard floor. The wood chips will decompose at a faster rate and the rolled out area is then in better condition for the harvesters. The University of California Cooperative Extension recommended keeping wood chips and shreddings in the orchards. They also stated that if well managed, prunings can become a source of organic matter and nutrients in the soil. These heavy duty tillers with 4 speed gearboxes are available in tilling widths of 83, 92, and102 inches.
