In summer and early autumn, you can often see special equipment in the fields and farmlands for raking and tedding grass, for harvesting and harvesting hay. Various functions are performed using attachments that are mounted on a tractor (for example, MTZ). Before acquiring any specific rake, it is necessary to determine the nature and scope of the work ahead.
Tedders
The most popular and popular ones are tractor rakes for tedding grass, the so-called tedders. It is convenient for them not only to stir and scatter grass, so that it is better dried out from precipitation and evaporation of the soil, but also to collect hay and straw in rolls. With the help of tedders, they perform the work that cannot be done manually. The quality of hay directly depends on the frequency of turning so that mold and trash do not form. This work is brilliantly performed by a multifunctional tractor rake - tedders.
Tedder classification
- The roll formation method is transverse and lateral.
- Used draft force - horse and tractor.
- Haymaking equipment - trailed, mounted, semi-mounted.
Tedders - mounted tractor rakes that are not difficult to maintain. The advantage of tedders is the ability to use them to stir mowing of various widths. The performance of tedders depends on such characteristics as:
- working width
- rotor speed;
- diameter of rotation;
- desired roll size.
Types and Features
Choosing a tractor rake (tedders), it is necessary to take into account the planned volumes of mowed grass and the productivity of the unit, which should provide these volumes. By the way, the rotary unit is the most maneuverable equipment, it is easy to operate. It is attached to the tractor using a mounted hydraulic system. The tedder is easy to transfer from operational to transport. In addition, it is profitable: saving up to 15% is a significant result.
The tractor rake has a rowing part fixed on the frame. It is attached to the tractor using a spoke with a trailer. The rake bar can be raised and lowered - this is done automatically. Rake teeth are made of spring-loaded steel, since stones and other solid objects can come across when scattering and raking grass. Qualitatively modeled tines have a favorable effect on the soil and provide a cleanly “assembled” swath.
Features of mechanisms allow to divide all rakes into the following types:
- rotary;
- wheeled;
- wheel-finger;
- transverse.
The most multifunctional device is a rotary device, respectively, it is also the most expensive. Functionally followed by a wheel-finger system, capable of raking and tedding hay, which is used exclusively for dry mowing. In the last place in terms of versatility and cost are the tractor rake transverse, since with the help of them it is possible to rake that hay that lies across the tractor's movement. This is achieved with the help of lowered teeth.
