Working parts and of agricultural machinery are made special steels that decompose under the influence various aggressive environments. In this experimental work, types metals were selected their corrosion properties determined. Studies have shown that, in general, metal materials used more likely to corrode, or an agriculturally active environment. According method, adhesion protective coating...
Children comprise a significant portion of the agricultural workforce and are exposed to many workplace hazards, including farm machinery, pesticides, poor field sanitation, unsafe transportation, and fatigue from doing physically demanding work for long periods. Migrant farmworker children face the additional hazard of substandard or nonexistent housing in the fields. Children account for a di...
Agricultural intensification is a highly specialized agri-food system that has contributed to raising food production worldwide due progress in agricultural machinery and technologies, the use of improved cultivars, external inputs such as fertilizers, irrigation, pesticides [...]
Statistics show that the travel of agricultural machinery to a work area and their movement during labour is the source of many serious accidents. The most dangerous in consequences prove to be those that occur during transport and associated with maneuvering tractors and machinery (about 30% of all fatal accidents). It can be assumed that at least some of these accidents were caused indirectly...

Measurement of the values of forces in tractor arms is of great importance due to draft of agricultural equipment. These values can be used for testing and evaluation of the agricultural machinery, selection of suitable tractor, etc. The tools which are used for measurement of the forces are called dynamometer. The main objective of the present study was to design and evaluate a load cell for i...
Agriculture is one of the major greenhouse gas (GHG) emission sources in China. This paper aims to identify the key factors that have led to rising GHG emissions in China’s agricultural sector in recent decades. This research allows for spatial dependence across provinces, making use of regional data from 31 provinces in mainland China. It investigates the effects of agricultural machinery, dif...
I propose to consider the question, “Can machines think?” This should begin with definitions of the meaning of the terms “machine” and “think.” The definitions might be framed so as to reflect so far as possible the normal use of the words, but this attitude is dangerous, If the meaning of the words“machine”and “think” are to be found by examining how they are commonly used it is difficult to e...

In order to improve the cooperative operation scheduling effect of agricultural machinery, this article uses particle swarm neural network study algorithm machinery and improves intelligent machinery. Aiming at mixed integer nonlinear programming problem, proposes a collaborative population intelligence linear programming. The outer layer improved IPSO module, inner simplex SIM optimal solution...
