Buy rollers for rolling crops on the MTZ tractor and get it right
Pre-sowing and post-sowing packing with annular,
ring-spur and spur rollers
During pre-sowing and post-sowing cultivation of the soil, field rollers are used to level and compact its upper layer. The maximum effect of this stage of soil cultivation is noticeable in especially dry years and when the sowing campaign is delayed for various reasons.

Buying a skating rink, inexpensive and of high quality, is a task that is easy to quickly solve after reading this article.
The use of the required type of roller is determined by the soil and climatic environment and the purpose of the compaction process. In other words - the climate, soil and technology with which it will be aggregated.

The best are rollers with an uneven surface (toothed, ringed, spur). They compact the soil to a great depth, which accelerates the emergence of seedlings.
The most popular are three-section water-filled rollers, whose ground pressure is different - from 2.3 to 6 kg per 1 cm of working width, the amount of filled water affects the parameters.
In the structure of ring rollers , the surface of which is ribbed, there is a row of metal rings mounted on the axis. They are characterized by three sections. The ring-shaped mechanism, in comparison with the smooth one at the same weight, is capable of compacting the soil to a great depth.
The ring-spur aggregates, in comparison with the standard ring-shaped ones, produce better soil compaction and crushing of existing lumps, moreover. with simultaneous loosening of the surface soil layer.
Rollers with an uneven surface are more efficient, since when the soil is compacted, the depth is much greater, which contributes to the acceleration of crop germination. Their use reduces the risk of soil blowing, crust formation and surface moisture evaporation, which is not the case with the use of smooth mechanisms.
In the functions of both ribbed and annular rollers, in addition to compaction of deep layers, parallel loosening of the surface soil layer is also laid.
The weight and dimensions of the units have an influence on the consolidation quality. The insignificant weight of the roller has the same insignificant effect, while the unnecessarily heavy ones unnecessarily compact the soil.
At the same time, the traction resistance of the mechanism with a larger diameter is reduced, therefore, it is preferable for the uniformity of movement that it be 40 cm, no less. If the movement is smooth and slow, the pressure on the ground increases.
Field rollers with the following parameters are considered the most preferable for compacting the soil:
coverage: 6-9 meters
roller disc diameter: 460-500 mm
aggregated with tractors: MTZ-80 / MTZ-82 / MTZ-1021
working speed: 8-12 ha / h
weight: 2400-3700 kg
It is most convenient to buy a field roller with a universal frame, which allows you to install both ring-toothed and ring-spur sections on its frame.
PRE-SOWING AND POST-SOWING
TILLING THE SOIL

Rolling after sowing until the emergence of shoots is used to destroy the loose hanging crust (with ribbed or annular rollers).
In spring, on winter crops, where bulging is observed, it is advisable to carry out rolling with ribbed rollers .
Green manure is also rolled before plowing and after plowing.
By rolling, they destroy the frozen ice crust on crops of winter and perennial grasses (ring rollers).
Today, pre-sowing packing has become widespread in the production of corn and sugar beets.
For spring crops of the late sowing period - this process in the pre-sowing stage of processing is often performed not once, but twice, which increases the yield of spring wheat.
The soil rolling carried out after the sowing process promotes better communication of seeds with the ground and, of course, as a result, a more organized germination.
PRE-SEEDING SOIL
FIELD ROLLERS:
prevents moisture evaporation from the lower loose soil layers
accelerates evaporation in the upper layer (condensation process)
promotes uniform seed placement, especially for small-seeded crops
enables capillary penetration of moisture to the seed bed
from the moment of visibility of seedlings - counteracts soil subsidence
creates conditions for better heating of the soil
promotes the revitalization of seedlings
POST-SEEDING SOIL ROLLING
The soil rolling carried out after the sowing process promotes better communication of seeds with the ground and, of course, as a result, a more organized germination.
The rolling process is also considered for settling grasses and winter crops with a visible protrusion of the tillering node after a not entirely successful overwintering.

Before you buy a field roller , you need to study its parameters and characteristics. Take into account the properties of the soil and think over with what it will be aggregated during pre-sowing and post-sowing treatment, because the weight and overall dimensions of the roller affect the quality of consolidation.

After using ring, spur and ring-spur rollers, there is no need for additional harrowing of the soil, since its surface remains slightly loosened.

To understand the quality and reliability of the purchased roller, as well as the terms of its operation, you should find out the following parameters (material and what they are made of):
center beam and beams
roller disc (its diameter)
When buying a roller, you should know it:
coverage (usually 6-9 m)
weight (usually 2400-3700 kg)
impeller disc diameter (usually 460-500 mm)
working speed: (usually 8-12 ha / h)
dimensions and parameters of folding / unfolding and with which tractors it is aggregated (MTZ, T-150, etc.)
the scheme of transformation from the transport position to the working position (does the tractor driver need to leave the tractor cab)
coverage: 6-9 meters
In the meantime, there is no need to know about it. ”
