DR offers three models of self-feeding chippers, these models are dedicated chippers. These particular chippers do not include shredders as they are dedicated to the continuous use of wood chipping four hours of use.

These chippers are for large gardens and estates or contractors. As the video shows, it’s much harder work to feed a traditional garden shredder. However, the smaller garden shredders and chippers definitely have a use in gardens. Moreover they can be very beneficial for those of us who don’t have the budget or need for a larger self-feeding chipper.

DR Self-Feeding Design

The DR self-feeding design make sure that you do not have to do the hard work, the chipper does this for you! The chipper has a large flywheel with a knife attached directly to the flywheel which will fly through the hardest of woods. A large flywheel can bring huge amounts of power to any machine making the most use of engine power.

The vertically designed hopper and perfectly angled chipping knife combined with airflow draw branches in and throw wood chippings out. Once you have pushed the branch into the machine the DR chipper will pull the branch through and make it instantly into chippings, in the meantime, you can be collecting your next branch for chipping.

The large hopper enables smaller side branches to be pushed through without pruning, saving time and effort. All models have side discharge chutes and the larger models have extending tubes which enables you to load your truck or trailer. This allows you to direct the chips to exactly where you want them for easy disposal.

Three Different Models

The three models differ in two primary ways; the first being the size of the engine, the second being the size of the flywheel. The rotating mass of a flywheel is the chippers power source, the greater the mass of the flywheel, the greater the mass of the chipper.

On early internal combustion engines, the power source came from the flywheel, carrying it over to the next stroke, which kept the engine moving. A 2 hp engine was massive in today’s standards compared with a 2 hp engine 100 years ago. It’s the same principle with the chipper flywheel, it keeps the power going.
