“…Such harrows are widespread in the fields of the northern region of Kazakhstan. The development of rotary tooth chain harrows was carried out in many studies [BAHRANI et al 2007;CLARK 2002;KURACH, AMANTAYEV 2020;MASLOV et al 2015;PHILLIPS 1998;PRASOLOV et al 2016;SAUDER 2003]. A significant drawback of the development and use of rotary chain harrows is the scale of the construction scheme and the large consumption of materials.…”

The accumulation of moisture from autumn and winter precipitation in poorly draining soil for plants in arid conditions during the initial stage of the vegetation period in the northern region of Kazakhstan was a severe production problem. Research methods included theoretical and experimental studies. In theoretical studies, the area of the treated surface by a chain harrow is determined. Then, the design of an improved harrow is proposed, including how the tooth chain tillage tools are positioned. Either as a "single action disc harrow" type with mounting four teeth on each chain link, or as a serial harrow with the tooth chain tillage tools located in a "diamond-shaped" double-action scheme with two teeth on each chain link. Experimental studies show that an improved harrow steadily performs the early spring harrowing process with a quality that meets normative requirements. In doing, so the working capacity is 4-5% higher than a serial harrow with a 4-5% lower fuel consumption. Furthermore, it is revealed that the early spring soil harrowing performed by tooth chain harrows allows the loss of productive moisture in the spring pre-sowing period by 1.8-1.9 times to be reduced compared to the untreated background.
