BACKGROUND: The method of reasonable selection an agricultural tractor tire set is a tool to compare and choose with the best properties, analyze features tire-soil interaction, evaluate feasibility installing proposed identify ways design improvement. relevance optimal for vehicles operating in agriculture related soil compaction by chassis that lead change its structure yield reduction. In ad...

Crop protection is mostly carried out spraying active chemical agents with potential impact on the health of environment, operator and consumer. Recently the European Commission played an important role in the protection of the operator with respect to the pesticide contamination during spray application. An active protection offered by tractor cab is a new requirement when the machine is used ...

The aim of the work is to scientifically substantiate a way improve technical, economic and agrotechnological performance indicators machine-tractor units, compiled on basis traction power equipment category 1.4, main technological operations in cultivation various crops by reducing level dynamic processes their connections. It established that elastic damping mechanism with nonlinear character...

ABSTRACT: In a tractor, the transmission system transmits power generated in engine to driving wheels, hydraulic systems, and take-off (PTO). There are several types of systems available Brazilian market ranging from simplest most advanced. Therefore, objective this study was verify different present 228 models agricultural tractors produced marketed Brazil during 2019. The tractor were grouped...

Results of theoretical studies dynamics the machine-tractor assembly taking into account influence a bearing surface profile were presented. It was established that in course operation, is exposed to number external factors leading change vertical loads on chassis and engine. Mathematical models tractor machine unit consisting pivotally connected arrangement trailed sower constructed. Such make...
