Claims

[Claims for Utility Model Registration] ■ A brake mechanism 9 is provided in the transmission mechanism 8 on the downstream side of the friction clutch 6, which is automatically and reversibly switched to a braking state in conjunction with the disengagement operation of the clutch 6. In the clutch/brake operating device for agricultural tractors, the brake mechanism 9 is constructed by forming the inner peripheral surface 30a of the boss portion 30A of the transmission gear 30, which is a component of the transmission mechanism 8, into an outwardly expanding shape. Formed on a tapered surface,
In order to slide the brake member 31 having a tapered braking surface 31a that can come into contact with the tapered inner circumferential surface 30a to a braking position where it comes into pressure contact with the transmission gear 30 in conjunction with the disengagement operation of the clutch 6. A clutch/brake operating device for an agricultural tractor, characterized in that: ■ The friction clutch 6 is a hydraulic clutch, and
Utility model registration claim No. 0 which is configured to slide the brake member 31 to the braking position using the pressure oil when the hydraulic clutch 6 is disengaged.
Clutch/brake operating device for agricultural tractors as described in 2. (2) The clutch and brake operating device for an agricultural tractor according to claim 0, wherein the transmission mechanism 8 transmits power to the power take-off shaft 7.
