BACKGROUND Agricultural tractor overturns without rollover protective structures are the leading cause of farm fatalities in the United States. To our knowledge, no studies have incorporated the spatial scan statistic in identifying high-risk areas for tractor overturns. The aim of this study was to determine whether tractor overturns cluster in certain parts of Kentucky and identify factors as...

Abstract The article presents the results of research conducted in order to improve accuracy and controllability driving along cotton row, which is an important factor increasing efficiency tractor semi-mounted harvesting machine. describes mathematical modeling movement guide wheels were obtained with help experimental tests.

Many parameters such as dynamic load of tractor drive wheels influence the traction of tractors. An increase in dynamic load of drive wheel increases the net traction, but excess dynamic load decreases the tractive efficiency that must be avoided. Development of tractor-mounted implements due to good maneuvering and weight transfer from front axle to rear axle led to effective performance of tr...

The efficiency expected from any pesticide depends largely on the type of plant protection machine used in spraying and operating parameters selected machine. Today, sprayers with different wing width are widely field spraying. Especially large working widths, it is difficult to work at high speeds due weight. In this study, wingless sprayer effectiveness was evaluated. Occasionally for instead...

The productivity of machine-tractor units depends on the length idle move performed in headland. Analytical dependences for determining when making T-turns by a unit with mounted machine field irregular shape have been specified article. Five types considered two variants – open turn and closed turn. Each them is carried out directions motion. A total 20 turns described. methodology specific co...
