Sowing combinators are time tested machines designed for pre-sowing preparation of the soil after ploughing wide range of working spans. Half carried machines are offered with the working span from 3 meter to 6 meter. Wide range of working spans covers both small farmers with small tractors and large agricultural holdings equipped with powerful tractors. Excellent leveling of the surface provides tine crumbling of clods. During one operation the soil is perfectly processed to the required position for sowing of corps. The land is perfectly leveled also due to smoothing harrows that can level and spread even high unevenness. Even a single run prepares the soil for sowing of crops perfectly. Due to high working speed, high working performance can be achieved even with lower working span of the machine. A key consideration here is that due to its well considered design and favourable weight machine can prepare the soil after ploughing during one run whereas the soil is processed not only on the surface but in the whole field.
