TAILIEUCHUNG - What’s New in Forage Equipment?

“Core medical equipment” refers here to technologies that are commonly considered as important or necessary for specific preventive, diagnostic, treatment or rehabilitation procedures carried out in most health care facilities. Today, there are more than 10,000 types of medical devices available. The selection of appropriate medical equipment always depends on local, regional or national requirements; factors to consider include the type of health facility where the devices are to be used, the health work force available and the burden of disease experienced in the specific catchment area. It is therefore impossible to make a list of core medical equipment which. | What s New in Forage Equipment Dr. Dan Undersander University of Wisconsin The forage equipment industry is changing in response to farmers needs. These changes consist of innovations to increase capacity to improve the usability of the machine and to improve the quality of the product. Most changes are occurring with existing equipment but some totally new product innovations are occurring. The size of machinery has increased to allow more-efficient harvesting. Some of this equipment will be used on larger operations and some will be used for contract forage harvesting which has expanded rapidly across the . in the last 15 years. Currently selfpropelled disc mowers have increased to almost 32 feet in three banks the largest rakes and mergers are 30 feet or wider and the largest forage harvester has a 1020 Hp V-12 engine and can harvest up to 400 t hour. The purpose of this paper is to give a few principles of hay and silage making and discuss machinery available relative to these principles. Mowers Some design improvements in mowers include differing knife types for different needs and changes with weight load distribution. Most growers are rapidly switching from sickle to disc mowers due to reduced maintenance requirement. Data is clear that the disc mowers do not reduce alfalfa yield or stand life more than that of sickle bar mowers. Differing knives are available for disc mowers and the choice among them should be made with some deliberation. The most common are knives that are angled at about 14o to enhance picking up downed forage. Mowers with these knives really do pick up downed forage better than those with flat knives. However angled knives pick up soil more when the ground is dry. Angled knives can add 1 to 2 ash to the harvested forage. So the grower must decide which is more important - picking up downed forage or having less ash in the forage. Cutting height should be adjusted according to management goals. Lower cutting height results in higher .
