  • Mechanical brush chipper feed control bar
    Patent number: 7721981
    Abstract: A mechanical control mechanism for the feed of a brush chipper is disclosed. The feed control bar has four positions: (1) forward or feed, (2) neutral, (3) reverse, and (4) stop. The hydraulic control valve has the three usual positions: (1) forward or feed, (2) neutral, (3) reverse. A function of the feed control bar is to provide the three function of the hydraulic control valve, plus the fourth in a fashion amenable to emergency situations. To these ends, the control bar has an extreme rearward position wherein the feed mechanism is stopped. The only permissible change to the stopped condition of the feed mechanism is to reverse the feed. Until a reset lever is manipulated, the hydraulic control valve cannot be put into a forward feed position.
