Effect of tillage implement (spring tine cultivator, disc harrow), soil texture, forward speed and tillage depth on fuel consumption and tillage quality

Abstract

Over the years, tillage became less intense due to environmental safety requirements in order to minimize fuel and labour time. Mostly, this is achieved by reducing the depth of tillage. However, highly cut winter rape stubble is the main challenge for reduced tillage to prepare clear soil, especially as the summer droughts intensify. The aim of this study was to determine the optimal tillage performances of the spring tine cultivator and compact disc harrow and establish the fuel consumption required to achieve the preferred level of soil structure formation and residue incorporation on loam and clay loam soil after a rape harvest. The fuel consumption depends on the desired level of soil tillage intensity, implement type, tillage depth (5 and 8 cm), and forward speed (1.4, 1.9, 2.5, 3.1, and 3.6 m∙s-1). The tractor “CASE IH 135” was instrumented with an additional data acquisition system and was used to perform the indicators of stubble tillage. The research examines the dependence of the tractor-implement regime mode on the soil aggregate ratio, which varied from 0.10 to 0.21, and the residue interblending ratio, which varied from 0.60 to 0.96. The relationship was established by obtaining the tillage quality level and reduced fuel consumption, which varied from 3.4 to 5.9 L·ha-1, depending on soil type. Minimization of fuel consumption and sufficient quality of oilseed rape stubble cultivation was achieved by reducing the depth but not the speed of tillage.

Full-Powershift Energy Behavior Tractor in Soil Tillage Operation

“…Furthermore, another relevant feature is the total mass of the implement and its disk-to-disk distribution, which is much heavier. These factors decrease the undesirable effects of the speed increase in harrowing, avoiding harrow fluctuation (Damanauskas & Janulevičius, 2022).…”

Superior Inferential Statistics of the Experimental Data of a Complex Experimental Cultivator

“…The dependence of some parameters of the dynamics of agricultural aggregates on the forward speed has been studied for many decades, with various solutions appearing in many publications (Letosnev, 1959;Moenifa et al, 2014;Cardei et al, 2019;Cardei et al, 2020;Ranjbar et al, 2013;Naderloo et al, 2009;ASAE, 2003 andMcKyes, 1985;Owen 1989;Larson, 1964;Fechete-Tutunaru et al, 2019;Cardei et al, 2023b;Damanauskas, Janulevicius, 2022;Dizaji, 2022;Karmarkar, Gilke, 2021;Askari et al, 2017;Al-Suhaibani, Ghaly, 2010;Elsheika et al, 2021;Deshpande, Shirwal, 2017;Saleh et al, 2021;Rashidi et al, 2013), for example. In general, the draft force depending on the main parameters that define the soil, the geometry of the working bodies, the mass of the machine, the forward speed, the working depth, and the working width was studied and modelled.…”

Analysis of the Dependence of Traction Resistance Force on Forward Speed for Tractor-Cultivator Aggregates

“…In particular, the experimental search for the dependence of the tillage draft force on the speed of advance of agricultural aggregates intended for soil processing began a few decades ago. Until then, the estimates of the traction force contained the contribution of the forward speed to the traction resistance force in simpler or more complicated analytical formulas, (Cârdei et al, 2023; Damanauskas & Janulevicis, 2022;Cardei et al, 2020;Cardei et al, 2019;Krasnicenko et al, 1964;McKyes E., 1985;Sandru et al, 1982;Sandru et al, 1983;Scripnic et al, 1979;Tecusan & Ionescu, 1982;Toma et al, 1978), purely theoretical or theoretical-empirical, (American Society of Agricultural Engineers, 2023; Moeenifar et al, 2014), sometimes with complex theoretical relationships including the geometry of the machine and working parts, (Al-Neama & Hertzilius, 2017).…”

“…The relationship between tillage draft force and the forward speed has been investigated by many researchers, (Moeenifar et al, 2014;Ranjbar et al, 2013;Naderloo et al, 2009;Singh et al, 2017;Al-Shamiry et al, 2020;Damanauskas & Janulevicis, 2022;Cardei et al, 2020;Cardei et al, 2019;Elsheikha et al, 2021;Kushwaka & Linke, 1996;Gatea A.A., 2013;Oprescu et al, 2021;Odero A.J., 2019;Salahloo et al, 2021;Afify et al, 2020;Kim et al, 2020;Saleh et al, 2021;Al-Neama & Hertzilius, 2017;Okoko & Ajav, 2020;Askari et al, 2017) for example. Some of the authors note the efficiency with which the variance of the traction resistance force highlights the influence of the forward speed (Naderloo et al, 2009).…”
