Cultivating aggregates
Cultivators, cultivators, compactors are machines used, as the name implies, to cultivate soil, usually pre-sowing. The simplest aggregates usually consisted of two or three rows of coulters and a finishing roller at the rear of the machine. Sometimes heavy harrows were also used instead of a roller. Such cultivators were most often aggregated with tractors like the Ursus c330 or c360. As time went by, more and more importance was attached to fine-tuning the field before seeding, and as a result double rollers or an additional roller at the front of the machine, in front of the coulters, were attached to the cultivators. Such machines were definitely better at seasoning the soil and breaking up clods, however, this was associated with a higher power requirement for such a machine.
Pre-sowing aggregates
From tillage aggregates we can distinguish another group of machines, namely pre-sowing aggregates. These are machines designed exclusively for shallow soil preparation before sowing. They are usually built with a pre-till roller in front of the machine, three or four rows of straight or goose-foot coulters, a levelling board (leveling rail) behind the coulters and a heavy pre-till roller (the most common was the CROSSKILL roller). The advantage of such a machine is very good field seasoning. This is particularly noticeable on heavy, clay soils where there are a large number of clods and clods, which, when not properly broken up, interfere with even crop emergence. The disadvantage of this type of machine is certainly its weight and length. This, of course, translates into power requirements and the lifting capacity of the tractor.
Cultivating aggregates – optimal operating parameters
The optimal operating parameters of tillage aggregates depend on several factors. Mainly it is about what kind of machine we will work with and what we want to achieve. If we want to refine the soil before sowing grain, rapeseed or corn, we will work relatively shallow (3 – 12 cm) with an operating speed between 10 and 12 km/h. Such working parameters will allow us to break up the clods well and disturb the soil as little as possible. The situation is different for potatoes. The soil prepared for this specific crop should be well loosened and as broken up as possible. In this situation, when choosing a machine for cultivation, we should choose an aggregate consisting of 3 or 4 rows of tines on a straight coulter with a roller, which will season our soil well and at the same time leave it plump. The depth of work in this case should oscillate between 15 and 20 cm at an operating speed of about 10 km/h. The situation is even different when we want to cultivate stubble. There is indeed such a possibility. When choosing a cultivator for shallow stubble cultivation, you should choose a machine with 4 rows of tines with a goosefoot coulter and a finishing roller, which compacts the soil well, reducing evaporation and stimulating the growth of weed seeds and volunteer seeds.
Manufacturer of cultivating units – AGROLAND
AGROLAND is a manufacturer of agricultural machinery, mainly cultivation equipment, including cultivating units or pre-sowing combinations. In the offer you will find cultivating units both for shallow presowing cultivation (TALOS), deeper cultivation for cereals, rapeseed, potatoes of 4 and 5 rows (COBALT, EUROCULTI) and cultivating units for organic cultivation (BIOCULTI) built with 6 rows of spring tines on a straight coulter or goose foot and a double row of harrowing fingers at the back of the machine. AGROLAND has established a solid position in the segment of cultivating units. Our machines successfully perform on any type of soil, from sandy, clayey to very fertile and heavy black soil.
