Farm tractors account for the majority of fatal injuries to adolescents working in agriculture and therefore remain a leading occupational priority. The question of whether these injuries occur because adolescents are assigned tractor jobs beyond their physical capabilities has not been answered. The purpose of this study was to estimate the activation forces required to operate controls on 40 ...

OBJECTIVES This article compares 2 variants of logging technologies at the motor-manual level: variant A - cutting and delimbing by means of a petrol chainsaw, skidding with the use of a cable winch mounted on a tractor (67-74 kW); variant B - cutting by means of a petrol chainsaw, skidding, debranching and cutting to length by means of a processor aggregated with a farm tractor (61 kW). MATE...

A computational fluid dynamics (CFD) code has been combined with a genetic algorithm (GA) to perform a two-dimensional drag minimization on the base region of tractor trailers. Few studies have been conducted with CFD driven by a GA due to extensive run times and the general non autonomous characteristics of meshing a suitable CFD geometry. This study solves the two-dimensional Reynolds-average...

ARTICLE INFO An agricultural tractor seat with passive suspension system gives a number of advantages when compared with currently available seat designs. Analysis on the vibration of tractor seat suspension system by using the different types of the suspension system is carried out for the different types of operation and analyze the suspension system separately to find out the reduction in th...
