Abstract

PURPOSE:To perform control of steering with a further low turn radius and to enable execution of smooth running during no control of steering, by a method wherein, in on agricultural tractor, a differentiating device is located to a drive system for right and left running devices. CONSTITUTION:Through control of the one clutch mechanism C, rotation of a second solar gear 20 engaged in a racing state outwardly of an output shaft 17 on the one clutch mechanism side is regulated, and the output shaft 17 on the solar gear side is reversed through a solar gear 19 by means of a power from a planetary gear 21. In this case, a rotation force is transmitted, in a manner to add a value being equal to the number of revolutions of the further reversing output shaft 17 to a value being 2 times as large as the number of revolutions under a straight running state, to the other output shaft 17 by a differentiating device A, which is formed with a carrier 14, rotated by a power from a drive pinion gear 12, and a bevel gear mechanism to transmit the rotation force of the carrier to the output shaft 17 for right and left running devices. This constitution naturally brings the running device outside a turn into a speed-up state, and enables control of steering with a further lower turn radius. Further, during no control of steering, smooth running is performed.
