The Rayco RC 16.5 drum-style brush chipper gives contractors a 17-inch-capacity machine loaded with features designed to maximize productivity and keep maintenance at a minimum. With fuel capacity of 50 gallons, the 140-hp Caterpillar diesel engine can run all day without stopping to re-fuel. The RC 16.5 also features Fuel Saver technology, which automatically decelerates the engine if the feed control bar remains in neutral for 60 seconds. To eliminate clutch maintenance, the unit features a hydraulic clutch that engages at the push of a button and never needs to be adjusted. A Torflex idler is designed to make belt adjustments simpler and does not require movement of the engine. The top-feed wheel is powered by a large planetary drive motor that provides increased torque while eliminating problematic couplers.
