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 ...

OBJECTIVES Many childhood farm tractor injuries occur during the performance of work that was assigned by parents, and some tractor work is beyond the developmental capabilities of children. This has been highlighted recently by a policy statement authored by the American Academy of Pediatrics. The objective of this study was 1) to assess child development knowledge of farm parents who received...

A desire for speed and lower costs, however, must be balanced with the appro...

Current commercial tractor guidance systems present to the driver information to perform agricultural tasks in the best way. This information generally includes a treated zones map referenced to the tractor's position. Unlike actual guidance systems where the tractor driver must mentally associate treated zone maps and the plot layout, this paper presents a guidance system that using Augmented ...

The ability to define in-field tractor load states offers the potential to better specify and characterize fuel consumption rate for various field operations. For the same field operation, the tractor experiences diverse load demands and corresponding fuel use rates as it maneuvers through straight passes, turns, suspended operation for adjustments, repair and maintenance, and biomass or other ...

A designed lightweight experimental shaker successfully used to collect ornamental oranges has been tested harvest fresh market citrus. The aim of this study was evaluate the removal efficiency and operational times device compared an orchard trunk shaker. Three different collecting systems were studied. ‘Caracara’ citrus trees tested. Removal efficiency, vibration parameters, fruit tree damage...

Abstract Farmers will often have a single tractor which they use for many different types of farmwork. A alone does not do any work, it is essentially always paired with, powering, and/or moving something else, an implement mounted on its front or rear. It particularly common in Europe, where there are small regional manufacturers, that farm contains tractors and implements from companies. The ...

Soil strength has traditionally been determined using the cone penetrometer, an instrument that provides highly variable discrete point measurements, making it difficult to detect statistically significant differences in the soil strength profile among treatments or locations. Generally, this problem has been addressed by obtaining a large number of measurements, a process that is time-consumin...
