MODERN TENDENCIES OF AGRICULTURAL TRACTORS

An empirical depreciation model for agricultural tractors in Spain

This work analyses the market value of second hand agricultural tractors in Spain for the period 1999-2002, with the aims of obtaining the most appropriate valuation models (through the use of ordinary least squares regression) and proposing an empirical model that estimates the true depreciation of these vehicles. Differences in tractor depreciation were studied in terms of the three horsepowe...

NOTES ON SOME MODERN TENDENCiES IN BOilER

The subject can be broadly classified under two headings: Water Treatment and Combustion. It is not the object of this paper to elaborate the methods of running efficiency tests and their attendant calculations, but rather to discuss the laboratory and factory work of the chemist in this more or less engineering subject. I think we can safely say that the day is past when accidents and expensiv...

Developmental Psychology: Main Problems and Modern Tendencies

T.Kobayashi. “How to Reduce Manufacturing and Management Costs of Tractors and Agricultural Equipment”. Agricultural Engineering International: the CIGR

The free trade and marketing across borders of food and agricultural products have reduced their prices, and have consequently been pushing down the prices of agricultural machinery. Utilizing the worldwide industrial infrastructure, the manufacturing industry, including agricultural machinery manufacturers, has expanded the worldwide sourcing of materials and components and complied with such ...

Initial rollover effectiveness evaluation of an alternative seat belt design for agricultural tractors.

A test program was conducted to determine the effectiveness of a seat belt restraint in preventing occupant movement in a rollover accident. A baseline type-2 seat belt (pelvic and torso restraint), and an improved type-2 seat belt restraint, both designed to restrict occupant motion in a rollover accident, were tested in a rollover restraints tester (RRT). Each seat belt was placed on a H-III ...
