In weighing up different options, look for effective bed pressure control, on-the-move break-back protection and sufficient front/rear overlap adjustment to eliminate missed strips in elds that demand some tight cutting curves. Agriculture Mower Safety Power mowers are presently available in four basic designs: the rotary mower, the power reel mower, the riding mower, and the tractor. e rotary mower is by far the most common; it is the focus of this entry. Pushed from behind, rotary mowers feature a single rotating blade enclosed in a case and supported by wheels. As the engine turns, it spins the blade. e blade whirls at 3,000 revolutions per minute, virtually 19,000 feet (5,800 meters) per minute at the tip of the blade where the cutting actually occurs. e best rotaries feature a horn of plenty (cornucopia) or wind tunnel shape curving around the front of the housing and ending at the discharge chute through which the mown grass ies out. Self-propelled models are driven by a chain or belt connected to the engine's drive sha. A gearbox usually turns a horizontal axle which in turn rotates the wheels. Some models have a big chain- or belt-driven movable unit that rises up off and settles down on the wheels. An accident with a rotary mower can cost you your life! We all know that a small push mower is a dangerous piece of equipment. Large agricultural mowers , by their nature can do much more damage to an individual. Following safety practices, using proper protective equipment correctly and keeping the mower in good repair will all help keep the operator safe. Mower Hazards e main source of danger with any mower is the blade, which does the actual work of cutting. In order to perform its task efficiently, the blade must be sharp and travel at a high speed. is sharp, high-speed blade can cause serious injury if a hand or foot is allowed to get under the mower deck while the engine is running. e manner in which the mower is operated on slopes is also important. Push mowers should always be operated across the slope so your feet will not get under the mower if you slip, nor will the mower roll down the slope and run over you. Pulling a push type mower is also dangerous, as your foot might slip under the mower. Riding mowers are generally more stable when operated up and down the slope. ere is also the danger of objects being thrown from under the mower by the blade, whose tip may be moving as fast as 200 miles per hour. A person struck by a rock or piece of wire thrown with such force could experience severe injury or even death. Fueling hot engines and smoking while refueling can result in serious burns, oen to large portions of the body. Another source of danger is that of carbon monoxide poisoning. Whenever an engine is started in an enclosed area, such as a garage, the danger of carbon monoxide poisoning exists. www.en.paulmueller.com
