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.

INTRODUCTION This list of Ohio Economic Insects and Related Arthropods was first assembled back in 1962-1964 while employed as the first "Survey Entomologist" of Ohio based at The Ohio Agricultural Research and Development Center, Wooster, Ohio. It was felt that such a list would serve as a valuable reference and useful purpose for commercial, government and public needs. This list was prepared and updated in cooperation with faculty of the Ohio Cooperative Extension Service, the Ohio Agricultural Research and Development Center, the Ohio Department of Agriculture, the Ohio Department of Health, the Ohio State University and the Plant Pest Control Division of the United States Department of Agriculture. Common and scientific names are listed under various host and habitat categories.
