Abstract

PURPOSE:To prevent danger beforehand by switching a stepping pedal to the neutral position by the stop of speed change operation, even if a manual lever is selected to the forward or rearward high seed position, in the traveling operation device for combine, etc. CONSTITUTION:When a manual lever 3 is operated from the neutral speed change position to the forward speed change side or rearward speed change side, a hydraulic continuously variable transmission 1 is operated to the forward speed change side or rearward speed change side through a manual interlocking mechanism 4 and a speed change operation shaft 2. Though, even if the manual lever 3 is at any speed change selecting position, the forward/rearward speed change operation by a stepping pedal is permitted by a preference mechanism 7, the manual lever 3 can be switched to the neutral position by a neutral switching mechanism 7a, when the speed change selection by the stepping pedal 5 is set to the deceleration speed side or retreat side rather than the forward speed side by the manual lever 3 or in the reverse case. Therefore, the advance or retreat at a high speed is prevented, and generation of danger is suppressed beforehand.

Prior Art and 1. Problems to be Solved by the Invention A hydraulic transmission device capable of changing gears using hydraulic pressure, a manual interlocking mechanism having a manual lever for shifting the hydraulic transmission device, and a foot pedal having a single foot pedal. In a traveling operating device for a vehicle, etc., which is provided with an interlocking mechanism and a priority mechanism that prioritizes a single pedal pedal shift operation regardless of the shift selection position of the manual lever, between the two interlocking mechanisms. This priority mechanism gives priority to the operation of the single foot pedal no matter which gear selection position the manual lever is in, and when the foot pedal is removed, the gear changes to the gear selected by the manual lever. Therefore, for example, with the 1 manual lever positioned on the reverse high speed side, after changing the gear forward using the foot pedal,
If you remove your foot from the foot pedal, the vehicle will move backwards at the high speed selected with the 1 manual lever, which may be dangerous.
