Abstract

PURPOSE:To make a shift lever so as not to interfere with people boarding or alighting, by making the shift lever so as to be displaced to the side of a steering shaft at a time when operating the lever to a neutral position. CONSTITUTION:A driver gets in and off a tractor as treading on a step 4 at the lateral part of a steering support frame 3,. and drives it after rotatively operating a steering wheel 1. In addition, he operates each of shift levers 5 and 6 whereby travel speed shifting takes place. These shift levers 5 and 6 are situated in a position distance away from the wheel shaft 2 at a running position, but when they are perated to be at a neutral position, these levers are displaced to the side of the wheel shaft 2.

（６）の把持が容易である。When work is interrupted without stopping the motive force m1 (11) and the operator temporarily exits the cockpit (lO), the shift levers (5) and (6) are operated to the neutral position groove (17). Therefore, the levers (5) and (8) are both deviated toward the handle shaft (2), and the operator is obstructed by the gear shift levers (5) and (8) when getting on and off the step (4). Difficult, again.
When performing a gear change operation, the gear shift levers (5) and (6) are moved to the running position groove (15) outside of this neutral position groove (17).
(1B), so the operator must move the gear shift lever (5).
(6) It is easy to grasp.
