Abstract
A conditioning implement having first and second conditioning rolls, one of which is movably mounted, includes a mounting system for selectively urging the movable roll toward the other roll. The mounting system includes a pair of mounting plates adapted for placement one on either side of the movable roll, with the mounting plates being pivotably mounted to a frame. An adjustment subassembly is connected to the mounting plates. In a first position, the adjustment subassembly exerts a maximum biasing force on the mounting plates for urging the movable roll toward the other roll with a maximum biasing force. In a second position, the adjustment subassembly relieves the biasing force exerted on the mounting plates, thus allowing movement of the movable roll away from the other roll to accommodate passage of a mass of material therethrough. A system is provided for interconnecting the adjustment subassembly with a lifting and lowering system for the conditioner.
