Forage harvesting is a rather painstaking and difficult task. Its main stage is directly mowing the grass on the field. To help agricultural workers, a number of devices have been invented, the performance of which varies quite a lot among themselves. Segment mowers have gained particular popularity.
Types of mowers
As a rule, all mowers are divided into 4 groups: self-propelled, mounted, trailed, semi-trailed (semi-mounted). This gradation is based on the methods of aggregation of equipment. As a rule, the location of the mower on the tractor includes a side hitch, which is located between the rear and front wheels. It is also not uncommon to use a semi-hinge at the rear, but the side linkage gives better visibility and makes steering easier. Semi-mounted or rear-mounted segment mowers are easier to mount/dismantle and achieve straighter angles when mowing grass around the field.
All mowers differ in the number of cutters. Industryproduces 1, 2, 3 and 5-bar mowers. Each of them is used only in a certain area. The smallest units are specialized for mowing grass in small areas, while the larger ones are specialized in endless meadows. Mowers are also distinguished by the location of the cutting units. There are 3 types of them: front, side, rear.
Segment mowers
According to the type of cutting device, the specifics of the plants to be cut and the requirements of consumers, all units are divided into 5 types: drum (rotary), rotary (for silage crops), fingerless (for legumes, rice and soybeans with a low cut), segment- disk, segmental-finger. It is the latter that are most popular with consumers. Segment mowers are chosen for simplicity, reliability, resistance to breakage. They handle hills and slopes with ease.
Segment mowers can have different types of cutter bar. Fingerless, respectively, do not have protrusions (fingers). They are easily replaced by another knife that goes towards the first one. Their stroke is 38 mm and the interval between the segments is 76 mm.
Segmented regular cut mowers are the most common. They were designed so that the number of segments and fingers is the same. The stroke of the knives is 76 mm, the interval between segments and fingers is 76 mm. A mower with a double blade stroke, like a normal cut machine, has the same number of segments and fingers. It differs from the previous species in that its knife passes through all fingers. The course of knives - 152, 4 mm. Interval betweenfingers and segments - 76 mm.
Segment mower
This machine is designed for cutting grass in natural and artificial grasslands. A small segment mower, the price of which is not too high, is quite affordable for small farms. It can be used in summer cottages and household plots, on slopes and roadsides. The small machine weighs no more than 35 kg.
Mower mounted segment is most often used on tractors for mowing large amounts of grass. Small-sized devices cost between 15-28 thousand rubles. The price of large mowers can reach 50-90 thousand rubles. (depending on brand).
