J.P. Carlton’s newest series in Drum Style Chippers- The Apaches. The 2518 features a massive 25-inch by 18-inch opening combined with a 37-inch diameter pocketed drum, allowing it to easily consume the largest trees. Aggressive feeding is handled by a dual pump hydraulic system controlled by a digital reversing autofeed system. The J.P. Carlton Apache series uses an exclusive long pivot arm for the 15¾” diameter top feed wheel. This long arm pivot gives the top feed wheel a smooth vertical lift path, allowing for easy opening over the largest butt ends. The Apache series also incorporates an exclusive Air Vortex Control to channel and accelerate discharge air, giving the Apache series high discharge velocities and great chip throwing power.
