ABSTRACT:
A hydraulic valve normally mounted at a convenient level for manual operation on a machine can be operated by a person's foot as opposed to his hand. Towards this end, there are provided mounting means for mounting the valve in an upside down position at the same level together with an elongated tube extending from the normally existing manually operable portion of the valve vertically downwardly terminating short of the floor. A transverse foot pedal is pivoted to the machine frame at the level of the lower end of the tube, this lower end in turn being pivoted to the same foot pedal at a point spaced from the first pivoting point. The arrangement is such that rocking movement of the foot pedal will actuate the valve in the same manner as manual actuation when the valve was upright.
