“…This was due to i) the greater working depth used for the hoe, as noted by Hasimu & Chen (2014), ii) the different action of the furrow opening mechanisms, and iii) the differences between the size of the elements, which affects cutting, shear and compaction that they cause to the soil. This result corroborates the findings of Herzog et al (2004), Mion & Benez (2008) and Modolo et al (2012), who also concluded that the hoe openers disturb the soil more than mismatched double-discs. However, the values were higher than those in the literature, mainly due to lower gravimetric moisture, which reduces the lubricating effect of water and therefore provides greater disturbance.…”

“…To characterize the performance of seeders' furrow-opening tools, Mion & Benez (2008) and , while evaluating soil disturbance caused by different tools, showed that the hoe opener disturbs the soil to a larger extent, in comparison to double-discs. Modolo et al (2012) also confirmed that the hoe causes more soil disturbance than the double-discs, and found values of 0.0045 m² for the former and 0.0037 m² for the latter. Moreover, Casão Júnior et al (2000) found that the hoe reduces plant residue on the furrows, although this effect may also be associated with speed, which is also reflected in other types of furrow openers, as explained by Celik & Altikat (2012).…”

The present study evaluated the effect of different associations between coulters and fertilizer furrow openers on soil disturbance, furrow depth and width, according to forward speed. The study was conducted on a farm in Santa Maria (Brazil/RS), in soil classified as sandy loam Ultisol. The experiment consisted of 24 combinations of treatments with three replications in a 2×3×4 factorial experiment. The combinations were formed by the interaction of the factors including: two types of furrow openers (hoe and double-disc), three types of coulters (no-coulter, smooth and offset fluted) and four levels of forward speed (1.11, 1.67, 2.22 and 2.78 m/s). Soil elevation and soil disturbance area profiles were obtained with the use of a micro profilometer, and disturbance values were calculated with the aid of computer software program Auto Cad. The disturbance area was not affected by speed; it was greater when using the hoe opener, and in association with the offset fluted coulter. Speed was inversely proportional to the depth of the furrows made by the hoe opener. Furthermore, the hoe caused the greatest furrow width (0.26 m) in comparison with the double-disc (0.24 m). The use of different coulters associated with furrow openers increased this variable (0.23 m for the no-coulter condition, 0.25 m with smooth and 0.26 m with offset fluted). The use of coulters combined with furrow openers reduces soil swelling, in approximately 8% for the smooth and 20% for the offset fluted.

“…Esta situação foi devida à maior profundidade de trabalho utilizada para a haste, pela ação diferenciada entre os mecanismos para a abertura do sulco e pelas diferenças entre as características dimensionais dos elementos que interferem nas tensões de corte, cisalhamento e compactação que estes provocam no solo. Este resultado está de acordo com o encontrado por MODOLO et al (2012), que também concluíram que SF mobiliza mais o solo que o SR. Contudo, os valores encontrados foram superiores aos da literatura devido principalmente à menor umidade gravimétrica, reduzindo o efeito lubrificante da água e, por consequência, proporcionando maior mobilização, além de outros contrastes entre características físicas do solo, como densidade e resistência à penetração, e pelas diferenças técnicas entre sulcadores utilizados.…”

RESUMO:O objetivo foi avaliar o desempenho operacional quanto ao requerimento de tração, consumo energético e eficiência de trabalho de associações entre eleme ntos de corte dos resíduos culturais e de rompedores do solo, em função da velocidade de deslocamento. Este trabalho foi realizado em propriedade agrícola situada no município de Santa Maria (RS), em solo classificado como Argissolo Vermelho e textura francoarenosa. O experimento foi composto por 24 combinações de tratamentos, em um esquema fatorial de 2x3x4. Estes foram obtidos pela interação dos fatores sulcadores (haste e disco), discos de corte (sem disco, liso e ondulado) e velocidades (1,11; 1,67; 2,22 e 2,78 m s -1 ). Os dados de desempenho do trator foram adquiridos com a utilização de instrumentação eletrônica. As associações entre sulcador e disco apresentaram melhor desempenho nas velocidades de 1,11 e 1,67 m s -1 por exigirem menor força de tração e consumo de combustível. Além disso, o uso de discos permitiu uma redução da ampliação da força de tração quando a velocidade passou de 1,11 para 2,78 m s -1 . A haste exigiu maior demanda de tração do que os discos desencontrados, e ambos, ao serem comb inados com os discos de corte, tiveram suas demandas aumentadas. Outrossim, a mobilização do solo não foi influenciada pela velocidade.

OPERATING PERFORMANCE OF FURROWERS AND CUTTING DISKS ASSOCIATION FOR NO-TILLAGE SYSTEM ABSTRACT:The objective was to evaluate tractor operating performance regarding traction application, energy consumption and work ing efficiency in association of crop residue cutting implements and soil breakers as the travelling speed. Experiment was performed at a farm in Sa nta Maria (RS ), Brazil. Local soil was classified as Red Ultisol with sandy loam texture. The experiment consisted of 24 treatment combinations in a 2x3x4 factorial scheme. The combinations were composed by interactions furrowers (furrow opener fixed and rotary), cutting disks (without disk, plain disk, and undulating disk) and travelling speeds (1.11, 1.67, 2.22 and 2.78 m s -1 ). Tractor performance data were acquired through electronic instrumentation. Furrower and cutting disk association had improved performance at speeds of 1.11 and 1.67 m s -1 for requiring less traction and fuel consumption. Furthermore, disks reduced required traction at speed range of 1.11 to 2.78 m s -1 . On the other hand, furrow opener device demanded higher tractions than mismatched disks; and both of them combined with cutting disks had increased demand too. Likewise, soil mobilization soil was not influenced by speed.

“…Based on these authors classification, seed-drill performance was considered regular only at the 3.4 km hG 1 speed, in which 51.5% of plants showed standard distribution and the remaining speeds showed unsatisfactory performance. Modolo et al (2012), evaluating seeding quality related to seed-drill speeds, reported that the increase in operation speed was the major factor over the parameters of seeding quality. Authors report satisfactory outcomes for speeds between 3.5-4.0 km hG 1 and regular outcomes for the operation speed of 5.0 km hG 1 .…”

A B S T R A C T Search for greater operating efficiency of seeders via increased speed in sowing operation has caused many problems in soybean plantability which may affect its yield components and final yield. Due to it, this study was carried out with the objective to evaluate a seeder performance under different operating speeds and its relation to soybean cultivars yield components and final yield in a no-till system. Experiment was laid out as a random block design, in a 2×4 factorial scheme, composed of two soybean cultivars and four seeder operating speeds. It was noticed that the seeder operating speed of 9.2 km hG 1 caused a reduction of 1.5 cm in the seed sowing depth resulting in an increase of 14% of exposed seeds. Moreover, soil disturbed area at the center of crop row showed an increase of 23.7% reducing so the seed emergence rate at 9.6% dayG 1 , affecting soybean final plant population what resulted in an yield decrease of 20%. The evaluated parameters showed similar results for the 7.7 and 3.4 km hG 1 seeder operating speeds, although, the best seeder performance was noticed at the lower operating speeds.
