New StumpKing model stumpcutter features Dial-a-Stump cutting speed selector, low-profile "Beaver Tail" boom, and new hydraulic system and clutch, said to speed setup and reduce operator time. Dial Selects Cutting Speed on New, Improved StumpKing By means of a new Dial-a- Stump cutting speed selector on '67 models of the StumpKing stumpcutter, operators can dial the exact cutting speeds re- quired for a particular stump while the cutter 'is in operation, according to its manufacturer, Brooks Products Division of The Tool Steel Gear & Pinion Co. Time lost in stopping the cut- ter to make necessary adjust- ments is eliminated, the com- pany says; more cutting time is delivered for each hour of oper- ator time. Other new features include a "Beaver Tail" boom of low profile for greater versa- tility and maneuverability, a new clutch design that permits the operator to stop rotation of the cutter head without stopping the engine, and a new hydraulic system that functions at all times when the engine is run- ning, thus allowing movement of other machine components even when the cutting head is declutched. Designed to be pulled by a pickup truck, the StumpKing offers a hydraulically controlled double cutter head, located at the rear of the unit, said to re- duce the toughest stump to mulch in minutes.
