ABSTRACT:
An operator lever device for a tracked vehicle equipped with a steering valve for controlling steering operations, a first transmission valve for selecting forward/backward traveling operation and a second transmission valve for controlling speed changing operations, has a rotary yoke shaft which is disposed horizontally in the front-and-rear directions with respect to an operator, a yoke mounted on an end of the rotary yoke shaft so as to be pivotable in the left-and-right directions, a cruciform member which is mounted to the yoke by pivot pins so as to be pivotable in the front-and-rear direction, and a single operator lever which is mounted upright in the cruciform member so as to be rotatable about the longitudinal axis of the operator lever. The operator can easily steer, select forward/backward operation, and change the speed stage of the vehicle by using only the single operator lever.
