装置。 The wheel loader is switched between forward and backward movement by operating an electric shift lever switch and engaging and disengaging the clutch via hydraulic pressure, and the electric circuit for the shift lever switch is equipped with a clutch cut-off switch and a pressure for brake pressure. A clutch control circuit for a transmission is provided with a switch and a relay, and enables the forward and reverse clutches to be disengaged or engaged when the brake is applied by operating the clutch cutoff switch,
The electric circuit is equipped with a foot switch that can be opened and closed in conjunction with the accelerator pedal for adjusting engine rotation.
A clutch control device for a wheel loader, characterized in that when the clutch cutoff switch is closed, the forward and reverse clutches can be disengaged or engaged by operating the foot switch.
