摘要： A three headed cutter is comprised of a cover assembly under which are located the three cutting head assemblies. The cover assembly, along with the cutting head assemblies, are designed so as to rotate around impediments, the cover assembly pivots around a central axis. The three headed cutter has a connecting member which connects it to the tractor by way of an articulated boom arm. The boom arm connects with the connecting member at a pivot point, from which a biasing means is also connected. The biasing means and pivot point allow for the cover assembly to take in the shock of hitting an impediment by having the boom arm move at its pivot point so as to move the cover without damage just before the start of its rotation around the impediment. Each of the three cutting head assemblies consists of a twin blade member and a caster. The caster rotates with the cutting head assemblies. The cover assembly is further supported by a support wheel which takes on the load from the connecting member and the articulated boom arm. The central axis has a motor from which extends downwardly a shaft member, which itself connects to a multiple track pulley which has three belts, one for each cutting head pulley, which themselves connect directly to the cutting head by way of a short shaft member. Tension pulley assemblies, which consist in a pulley and biasing means assembly, keep tension on the belts.
