Previous studies have reported that tractors are responsible for high proportions of fatal and nonfatal agricultural injuries. However, many common and preventable risk factors, conditions, and associated costs related to tractor-related injuries have not been investigated. This case-based study used workers' compensation data to investigate tractor-related injuries. The objectives of this stud...

Aim of this work is looking for a correlation between footprint and soil penetration volume of treads in agricultural tires. Three tyres of different dimensions, fitted on the same tractor with different pressures and loads (N=not ballasted; Z=ballasted) were tested for defining the area of the single footprint shape (SF and SaF), of the multiple footprint shape (MF) and the volume of tyre in s...

The article presents research results of a machine-tractor unit that performs two technological operations simultaneously: (i) chopping plant residues (sunflower stubble); (ii) covering the chopped stubble with soil. first operation is carried out front-mounted chopper, and second one rear-mounted plough. chopper’s working devices are rotated by tractor’s front power take-off (PTO), which has o...

A 58-yearold burning and trashing trial receiving fertiliser and no fertiliser was used to quantify treatment effects on soil penetrometer resistance. The results showedthat penetrometer resistance was significantly lowerin thosetreatments whereno fertiliser wasapplied. Increased soilwatercontentin treatments witha trashcoverdid notreducepenetrometer resistance values in the soil wherefertilise...

Farmers experience whole-body vibrations when they drive tractors. Among the various factors that influence the vibrations to which the driver is exposed are terrain roughness, tractor speed, tire type and pressure, rear axle width, and tractor seat height above the ground. In this paper the influence of tractor seat height above the ground on the lateral vibrations to which the tractor driver ...
