In summer and early autumn, in the fields and farmlands, you can often see special equipment for raking and tedding grass, for harvesting and making hay. Various functions are performed using attachments that are mounted on a tractor (for example, MTZ). Before purchasing any specific rake, you need to decide on the nature and scope of the work to be done.
Tedders
The most popular and in demand are tractor rakes for tedding grass, the so-called tedders. They are convenient not only to ted and scatter the grass so that it dries better from precipitation and soil evaporation, 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 dust do not form. This work is brilliantly performed by multifunctional tractor rakes - tedders.
Tedder classification
- The swath formation method is transverse and lateral.
- Used draft power - horse and tractor.
- Hay equipment -trailed, mounted, semi-mounted.
Tedders - mounted tractor rakes that are easy to maintain. The advantage of tedders is the ability to use them to ted swaths of various widths. The performance of agitators depends on characteristics such as:
- width;
- rotor speed;
- rotation diameter;
- desired swath size.
Types and features
When choosing tractor rakes (tedders), you need to take into account the planned volumes of mowed grass and the performance of the unit that 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 hinged hydraulic system. The tedder is easy to transfer from working to transport state. In addition, it is profitable: saving up to 15% is a significant result.
Tractor rakes have a rowing part fixed on the frame. It is attached to the tractor with a spoke with a trailer. The bar with a rake can be raised and lowered - this is done automatically. The teeth of the rake are made of strong spring steel, as when scattering and raking grass, stones and other hard objects can come across. Well-designed tines are good for the soil and ensure a cleanly "collected" swath.
Features of the mechanisms allow us to divide all the rake into the following types:
- rotary;
- wheel;
- wheel-finger;
- transverse.
The most multifunctional device is a rotary, respectively, it is also the most expensive. It is followed in terms of functionality by a wheel-toed system capable of raking and turning hay, which is used exclusively for dry mowing. In last place in terms of versatility and cost are tractor transverse rakes, since they can be used to rake hay that lies across the movement of the tractor into a swath. This is ensured by lowered teeth.
