Abstract:

An articulated arm and cutter attachment for mounting on a tractor has a pair of elongated vertical booms pivotally connected to one another at their top ends. The lower end of one of the booms is pivotally connected to a beam extending laterally from underneath the tractor chassis. The other boom has a telescoping lower end on which is mounted a foot which supports a rotary cutter. An upper portion of the beam connected to the tractor is inclined outwardly, and an upper portion of the other beam is inclined inwardly to allow the arm to reach out a substantial distance and extend over obstacles such as fences. Pivoting mechanisms in the foot allow tilting of the supported cutter over a wide range of angular positions. Hydraulic cylinders are provided for carrying out movement of the arm, along with hydraulic fluid lines and controls. Yieldable mounting of the foot provides for breaking away of the cutter upon striking an obstacle.
