Abstract
A ripper operating device is configured to perform operations of a ripper of a work vehicle. The ripper operating device includes a support portion, an operating lever, and an operating switch part. The operating lever is supported by the support portion to be movable with respect to the support portion in a first direction to perform a first operation and non-movable in a second direction. The first direction intersects a front-and-rear direction at an intersection point corresponding to a neutral position of the operating lever to form an acute angle with the front-and-rear direction on a rearward-outward side of the intersection point. The second direction is substantially perpendicular to the first direction and substantially matches with a direction in which a forearm of an operator extends when operating the ripper. The operating switch part is arranged on the operating lever to perform a second operation other than the first operation.
