The speed ratio parameters of transmission are crucial factors that affect a vehicle’s power, economy, and comfort. Due to the complex working conditions, multiple modes, wide range ratios agricultural tractors, designing optimizing in power-shift transmissions is challenging task. This paper proposes optimization method based on life cycle utilization rate general-purpose tractors. optimized s...

Experimental research on agricultural tractor movement, acquisition and archiving of kinematic features is an important issue in the analysis braking acceleration processes. The obtained traffic parameters depend environmental conditions, condition type pavement, load, tire pressure area tire-pavement cooperation. factor, particular process, determined by coefficient friction enabling assessmen...

Abstract The aim of the paper is analysis consumption electric energy which necessary to drive a farm tractor with an motor as unit under conditions varied loading power transmission system. object research was model where combustion engine replaced dc motor. During tests, decrease voltage and current strength collected from supplying batteries function time in relation mass trailer, temperatur...

excessive cutting depth during leveling of agricultural land increases power needed by the tractor drawbar and will result in undesirable slippage and excessive strain on the tractor engine.  the result of sustained excess will be the break-down of the tractor. an auxiliary blade depth controller to prevent overloading during leveling was designed, fabricated and evaluated in this study. the sy...
