PURPOSE: To extend the effective range of transmission output and enable the use of an auxiliary section countershaft drive PTO device by comprising a main transmission section connected in series with a splitter type auxiliary transmission section connected in series with an extended range section. CONSTITUTION: A range section clutch 206 has a first position for rotationally coupling a sleeve shaft 200 to an output shaft 74 to allow the actuation of a standard splitter type auxiliary transmission section 14. At the second position of the clutch 206, as the clutch 206 allows independent rotation between the sleeve shaft 200, the output shaft 74 and a range section output shaft gear 202, an auxiliary section countershaft 80 can be driven irrelatively to the output shaft 74 for PTO. At the third position of the clutch 206, when the main transmission section 12 is at a low gear ratio, the output shaft gear of the range section 15 is rotationally coupled with the output shaft 74, the sleeve shaft 200 can rotate irrelatively to the output shaft 74, therefore wide deceleration range is obtained. |
