The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people we...
Noise injury in agriculture is a significant yet often unrecognized problem. Many farmers, farm workers, and family members are exposed to noise levels above recommended levels and have greater hearing loss than their non-farming contemporaries. The aim of this study was to gather up-to-date information on farm noise levels and to enhance the quality of information available to assist farmers i...
In this study tractive efficiency (TE) of MF285 and U650 tractors during moldboard plowing were evaluated and compared. Field experiments were conducted at the Experimental Station, College of Agriculture, Shiraz University, using a randomized complete block design with a 3*3 factorial. The soil was sandy clay loam with an average moisture content of 18% b.d. from zero to 30 cm depth. Test trea...
a r t i c l e i n f o As the functionality of ISOBUS compliant agriculture machines increases, demands on the underlying bus network capacity increase as well. Therefore, to prevent potential bottleneck performance of critical applications, bus utilization must be carefully optimized. In this paper, a methodology for transparent compression/decompression of Object Pool files arising from the us...
Traumas connected with agricultural production can result in serious injuries and mortality. The objective of the study was to describe the characteristics of agricultural machines related work injury cases admitted to the Emergency Department, and to asses factors related to injury severity and hospital admission in the Central Anatolian Region of Turkey. All the cases presented related to inj...
This paper presents experimental research evaluation of the vibration exposure for the health risk prediction during vehicle operation. The vibration measurements were carried out on a recreational vehicle and two types of agricultural tractors. The vibration levels were measured for different surfaces and vehicle speed conditions. Based on the analysis of the results in the small agricultural ...
Nacrtak The authors tested two alternative treatments for small wood extraction in protected conservation areas, respectively based on direct skidding by small crawler tractors and integrated horse bunching and crawler tractor skidding. The integration of horse bunching with tractor skidding proved cheaper than direct tractor skidding, and allowed extending the distance range of horse skidding....
To solve the serious pollution problems of traditional fuel tractors and short continuous operation time pure electric tractors, a hybrid tractor with cell as primary power source battery auxiliary is proposed. A novel energy management strategy was also designed, which integrates thermostat control strategy, following fuzzy logic control. The utilizes advantages different algorithms realizes r...
85 years ago, on 11 July 1937, the production of STZ-NATI, famous and deservedly popular tracked agricultural tractor, was launched at Stalingrad Tractor Plant. This tractor first which had completely domestic deisgn. Development this is an example effective collaboration between design engineers STP scientists All-soviet Scientific Research Insitute (NATI). In comparison with predecessor, STZ-...
