下方への回動を阻止されるのである。 The depression stopper 3 is rotatable in the direction of the arrow shown in FIGS. 3 and 4, and a fulcrum crossing spring 10 is locked to a pin 12. As shown in FIG. 4, the step-in stopper 3 is rotated upward, the locking portion 3a is locked with the locking pin 15, and the state in which it is biased by the fulcrum crossing spring 10 is the first step-down stopper position 3'. The second step stopper position 3'' is the state in which the step-in stopper 3 is rotated downward as shown in FIG. 3 and the locking portion 3a is locked with the locking pin 15.
As shown in FIGS. 3 and 4, the outwardly projecting portion 3c of the depression stopper 3 is connected to the clutch pedal 2.
It engages with the inward protrusion of the blade, and is prevented from rotating downward in the first stage completely cut state and the second stage completely cut state, respectively.
(ヘ) 発明の効果
本発明は以上の如く構成したので、次のような
効果を奏するものである。(F) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

生じ発熱が生ずるという不具合いが防げ、クラツ
チデイスクプレートの焼き付き現象が防止できる
のである。 First, a depression stopper is provided at the first depression position 2' of the two-stage clutch pedal, and by rotating the stopper, it can also be used as a depression stopper for the second depression position 2''. Because of this structure, unlike when the stopper was attached only at the 2'' depressing position of the 2nd stage as in the past, the pedaling force feeling at the boundary between the 1st and 2nd stages is not clear, so the 1st stage clutch must be pressed sufficiently. By using the clutch without interruption, problems such as the clutch slipping and generating heat can be prevented, and the phenomenon of seizure of the clutch disk plate can be prevented.
第２に、この踏込みストツパー３を、１個のス
トツパーを回動することにより１段目と２段目の
両方に使えるので、従来の如く走行の停止と同時

必要が無い場合や、作業機を駆動しない場合には
１段目の走行クラツチ断接のみの踏込みストツパ
ー３として利用したい場合にも簡単にこの状態に
切換えることができるのである。 Second, this stepping stopper 3 can be used for both the first and second stages by rotating one stopper, so the PTO power of the work equipment can be stopped at the same time as the travel stops, as in the past. If it is often necessary, it is possible to set up to the second step stopper 3. Conversely, if there is no need to disconnect or disconnect the power for the work equipment, or if the work equipment is not driven, the first step stopper 3 can be used. Even when it is desired to use the depressing stopper 3 for only connecting and disconnecting the traveling clutch, it can be easily switched to this state.
