説明

In order to find the optimum speed ratio between front and rear wheel of four-wheel drive tractor, a test tractor equipped with a hydrostatic transmission at the front wheel drive system was manufactured by way of trial. Using this tractor, various traction performance tests were done on a concrete road and rice stubble field. In these tests, a peripheral speed ratio of front to rear wheel was changed from 0.8 to 1.2. From the test results, the effect of front wheel assist was notable when the tractor was operated at the peripheral speed ratio of about 1.1 showing lower slippage and higher drawbar horse power than at the peripheral speed ratio of 1.03 to 1.05, which is seen in ordinary tractors on the market.
