Predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. So, doing a timely agricultural operations, more accurate measure of the amount of income  including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...

Abstract The purpose of this study was to spatially identify the degree mental fatigue a farm tractor operator within experimental field during grain sowing. In addition, determine possible relationships between space conditions and workload. conducted on John Deere 6210R aggregated with Horsch Pronto 4D seeder. operated tractor's on-board computer, seeder's control Trimble CFX-750 satellite na...

Purpose: Agricultural work in Colombia, particularly small and medium-sized farms, is lagging behind terms of technology; advances such as precision agriculture (PA) are unknown. This project managed to promote the implementation PA technologies primary tasks land adaptation, by comparing efficiency indices when conventional practices were used against use new technologies.

Plastic contamination in marketable cotton bales, predominantly from plastic wraps used John Deere round module harvesters, poses a significant challenge to the U.S. industry. Despite rigorous manual efforts, intrusion of into gin’s processing system persists. We have developed machine-vision detection and removal aimed at mitigating this problem. This employs inexpensive color cameras detect o...

Abstract The aim of this research is to present a simulation model for reducing economic damages of mechanized wheat harvesting in the weather conditions of Khuzestan province and similar areas. The simulated model is composed of three sub-models, for determining of the appropriate working hours, grain losses, and economic sub-model. In order to determine the appropriate working hours, a mathem...

The manuscript describes the results of an experimental study level PM (particulate matter) emissions arising from combustion two selected types biomass (i.e., rapeseed straw pellets and engine biofuel (biodiesel, FAME)), which were derived rapeseed. biofuels compared with those obtained their traditional counterparts wood diesel fuel). Both burned in a 10 kW boiler designed to burn these fuels...
