Abstract
PURPOSE: To drive a tractor at ultra-low speed without using an oil pressure drive device in the ultra low speed region, by the method wherein, in the titled device in which an oil pressure device is provided in addition to a gear speed change device, a differential deceleration gear mechanism is connected to the oil pressure drive device.
CONSTITUTION: To drive a tractor at ultra low speed, set the main speed change lever neutral, set the selection lever at the position of ultra deceleration mechanism operation, engage pawl 42a of shift gear 42 with stationary pawl 11a, and set the control valve of oil pressure motor 12 at the operating position. By this, oil pressure motor 12 rotates, the rotation of output shaft 12a is transmitted to casing 43, and thereby casing 43, together with planet gear 47, is caused to rotate about shaft 41. At this time, shaft 41, and consequently gear 49, are fixed, planet gear 47 rotates with the rotation of casing 43, the difference between revolution and rotation is transmitted to sleeve 50 via gear 50a, and traveling drive shaft 22 is rotated at ultra low speed via gears 57, 29.
