Norton, head of the engineering! department at Massachusetts Cranberry Ex- periment Station has designed an all-purpose "bog ; This, with a ditch digger and a separator of a non-bounce type are expected to be on display or demonstrated at annual meeting of Cape Cod Cranberry Growers Association, August 18th at the State Bog. Norton describes the experimental bog vehicle as follows: The experimental bog vehicle is being designed and built with the main purpose in mind of provid- ing a means of transportation of heavy loads on the bogs that will do a minimum of damage to the vines. For example, it is honied that a payload of four yards of sand or 500 gallons of spray ma- terial, or 100 boxes of cranberries, might be transported on the bog without injury to the vines. It is also hoped that the vehicle will be able to span ditches up to 3 feet wide without bridging. It is emphasized that this ve- hicle is strictly experimental. It is neither inexpensive or light in weight. It weighs approximate- ly 5500 pounds. There will un- doubtedly be a number of short- comings become apparent as the machine is tested. However, ef- forts will be continued to over- come these problems as they ap- pear. The basic design of the machine centers around the theory that a wide belt with closely spaced support rollers would distribute the weight of the vehicle and its load over a large area just as the track on a track-type tractor does. Thereby reducing the unit pressure on the vines. The belt on the machine is 4 feet wide and the drive rollers are 10 feet on center. This pro- vides a contact area of 40 square feet or 5760 square inches. With 4 yards of sand the weight per square inch will be approximately 3 pounds. The support rollers are 9 inches apart. This spacing of the support rollers will undoubted-. Front view of experimental bog buggy, designer John
