Rayco’s RC 12 brush chipper offers an 86-hp Cat diesel engine and Rayco’s patented Pulse down-pressure system to ensure performance on any type of material. This heavy-duty drum-style chipper weighs more than 6,000 pounds and is built to withstand harsh jobsite conditions. A planetary drive motor is directly bolted to a large-diameter feed wheel giving it the size and torque to climb logs or dense material without hesitating or operator intervention. The down-pressure system has constant 325 pounds of pressure that provides an additional 2,175 pounds applied every 3 seconds for a total of 2,500 pounds of crushing power.
