Mower

The mowing describes the technical equipment needed for mowing grass, grain, or other fruits, the roots remain as crop residue on the surface and eventually drive out again. In technical terms this activity is referred to as " mowing ".

History

In the early days of human harvesting knife, sickle and scythe used as cutting and harvesting tool. With advent of industrialization first, the cutter bar was developed, which was supplanted since the seventies of the last century, especially in the grassland of the rotary mowers.

Mähverfahren

• When the crop silhouette of a blade of a knife or blade is pressed and cut against a counter edge. The advantage of this technique lies in the clean cut edge on the remaining plant, what are führt.Typische representatives of this cutting technique to a growth advantage over other cutting methods of cutter bar with Fingermähwerk or
• Double cutter bar and the

• In the free section is omitted counter blade and cut the crop due to the rotational speed of a rotating blade and the inertia of the plant. The scythe is classified in that category. The disadvantage of this technique is that the crop is cut off by blurring cutting and no clean cut edge is created. However, high work with this cutting technique are possible. Rotary mowers,
• Schlegelmähwerke,
• Sickle mower and
• Brushcutters work on this principle.

Working widths

While the cutter bar in the grassland area usually has a working width of up to 2 m, it reaches in cutting works by combines a width of up to 15 m. Rotary mowers achieve in grassland management working widths of 4 m as a single machine. In the combination of several Mowers on a carrier vehicle of over 10 m.

Power requirement

The power consumption of Balkenmähwerken is about 2 kW per meter of working width, whereas the requirement for rotary mowers Kreiselmähwerken about 7 kW, and flail mowers is about 22 kW per meter of working width.
