The equipment for seedbed preparation in the conservative system is a combiner composed of harrow type working bodies with the “XL” type notched disc, two rows of active bodies type chisels for soil processing, a row of levelling discs, respectively a rear roller that can work up to speeds of 12 km/h and to depths of 30 cm. This paper presents the experimental research conducted with this type of combiner in the aggregate with a tractor of 350 HP, aiming to determine the qualitative indices in a scarified field, with very large and hard lumps resulting from the scarification process, which led to high fuel consumption (above average) and also to the obtaining of very good qualitative indices (degree of incorporation of plant debris and crumbling degree). The experiments were conducted at six working depths: 5/10/15/20/25/30 cm and four movement speeds: 2/2.5/3/3.5 m·sE-1, while also determining the soil moisture corresponding to the six depths, respectively soil compactness at these working depths.
