Shift operation structure of a walking type management machine

摘要

(57) [summary] [purpose] over to a travel operation arm and the PTO-actuating arm to devise a simple linkage mechanism, casually a reverse position in a state in which the working device that receives the power of the PTO system has been driven by preventing the operation of to, to achieve the safety improvement of work. [Configuration] with the first shift rod 21 for the traveling speed on the side of the Emissary Yon case 1, the second equipped shift rod 22 and the pushing and pulling operably for PTO transmission, the first shift rod 21, the vertical axis from the traveling speed lever 19 to be swung as well as operatively connected to the running for the operation arm 26 that has continuously provided around the heart, the second shift rod 22, from the PTO transmission lever 20 which is pivoted around the front and rear axis In the continuously provided the shift operation structure of a walking type management machine linked linked to the PTO for the operation arm 31, a cam groove that said the check member 35 in the running for the operation arm 26, the restraint member 35 is engaged with the PTO for the operation arm 31 36 is respectively arranged, the PTO transmission lever 20 is the restraint member 35 only to be operating the traveling gear lever 19 to the reverse position R in a state that is in the neutral position It has set the shape of the cam groove 36 against.
