Abstract: PROBLEM TO BE SOLVED: To enable a slight speed change of a speed change operating device that holds a gear lever with a friction mechanism and keeps a continuously variable transmission in an operation desired speed state. SOLUTION: When the gear lever 50 is operated to a forward region or a backward region, it is connected to movable members 71f and 71r by a lever clutch mechanism 100. When the gear lever 50 is moved to a deceleration side, ratchet claws 93 engage with ratchet teeth of the movable members 71f and 71r and movable members 72f and 72r for braking controlled by friction mechanisms 80f and 80r are connected to the movable members 71f and 71r. When the gear lever 50 is moved to an acceleration side, the ratchet claws 93 are removed from the ratchet teeth of the movable members 71f and 71r, and the movable members 71f and 72r turn relatively to the movable members 72f and 72r for braking. When the gear lever 50 is stopped, the ratchet claws 93 engage with ratchet teeth of the movable members 71f and 71r and the friction mechanisms 80f and 80r control the gear lever 50.

Abstract: PURPOSE: To provide a grading part capable of suppressing discharge of a treating material to the outside of the machine, reducing the third loss and excellent in workability by providing a control means for carrying out driving control of a blocking member to a blocking side as the treating material amount decreases. CONSTITUTION: This grading part of the combine is equipped with a driving type blocking member 34 for opening and closing a dust discharging port 17 formed so as to face the end part of an oscillating and grading apparatus 12, a sensor S2 for detecting the treating material amount and a control means for carrying out driving control of a blocking member 34 to a blocking side as the treating material amount decreases. Furthermore, the treating material amount detecting sensor S2 is preferably engaged with a grading air control mechanism so as to decrease grading air mount from a winnower 13 as the treating material amount decreases.

Abstract: PURPOSE:To provide a shaking sorter for a thresher in which a grain sieve is made of a resin material and a movable grain pan is set in front of the sieve, thus the grain sieve can be prevented from clogging. CONSTITUTION:The grain sieve is formed from a resin material to remove the level differences between the wires which run in the longitudinal and the transverse directions to form the sieve meshes thereby inhibiting short straw wastes from thrusting between the wires and improving water repellency. A grain pan 6b slidable back and forth is attached to the front of the grain sieve 7 whereby the sorting range of the grain sieve is made variable.
