The 1712 12-in. disk-style wood chipper incorporates a 48" x 28" infeed opening, allowing it to swallow tops with little or no trimming. The 10 1/2-in.-diameter feed rollers accept the wood with minimal wrapping. The 32-cu.-in. displacement hydraulic feed motors provide the power to pull and collapse limbs and tops. A digital adjustable autofeed monitors engine rpm, and has the ability to start and stop the feed of material automatically based on parameters set by the operator. The compact, 5,400-lb. unit is maneuverable in tight places and is towable by smaller chip trucks.
