Publication number: 20130239538Abstract: This mower blade design is intended to cut vegetation (turf, grass or other similar growth) by employing an extreme low or indirect angle of blade attack instead of a direct, head-on, 90 degree impact angle of attack used by most conventionally blades available today. Design is especially effective where the mower is to be operated in sandy or rocky soil. The design increases the life of the blade from one year season to four or five years. Design allows the blade to remain sharp since its cutting edge is out of the direct path of sand, rocks and other debris. Cutting on a low, indirect angle provides shearing or slicing action producing an improved cut similar to that of “reel” mowers. This blade is designed to be used in all conventional rotary mowers.Type: ApplicationFiled: March 16, 2012Publication date: September 19, 2013Inventor: David O. Gohsman
