Drawbar Pull and Its Effect on the Weight Distribution of a Tractor
Polcar, Adam; Renčín, Lukáš; Votava, Jiří (Mendelova univerzita v Brně, 2017)This article aims to experimentally determine how the tractor's weight distribution changes during loading by drawbar pull, and how the tractor's weight affects its drawbar pull properties. Drive wheel ballasting has a ... -
The Effect of the Tractor Tires Load on the Ground Loading Pressure
Renčín, Lukáš; Polcar, Adam; Bauer, František (Mendelova univerzita v Brně, 2017)The contribution, based on the experimental measurement, analyses the issue of a specific pad loading pressure in relation to radial wheel load and tire inflation. Tile inflation in terms of allowed radial load, which we ... -
Effect of various ignition timings on combustion process and performance of gasoline engine
Tunka, Lukáš; Polcar, Adam (Mendelova univerzita v Brně, 2017)This article deals with the effect of the ignition timing on the output parameters of a spark-ignition engine. The main assessed parameters include the output parameters of the engine (engine power and torque), cylinder ... -
The impact of upper link length on the output parameters of a tractor set
Renčín, Lukáš; Polcar, Adam; Bauer, František (Mendelova univerzita v Brně, 2019)The aim of the article is to find out the impact of the increase in the force in the upper link of a three-point hitch on the performance parameters of the tractor set Claas Arion and the carried plough Pöttinger equipped ... -
