Abstract
The aim is to improve operability in vehicles such as skid steer loaders and to reduce the burden on the operator. It is made easy to switch between a first operation pattern wherewith only one operation apparatus of two operation apparatuses is used in driving two actuators, and a second operation pattern wherewith the two actuators are driven using both of the two operation apparatuses. It is made possible to hold operation positions, and to release held positions, whether with an operation lever apparatus that is capable of operation in only one directional component or with an operation lever apparatus that is capable of operation in two directional components in the forward and backward direction and in the left and right direction. When a change to a first combination is designated by a pattern switching lever, the first combination (first operation pattern) is switched to by switching means. This effects correspondences between operation direction signals output from one operation apparatus of two (left and right) operation apparatuses and the drive directions of left and right running actuators. It is thereby made possible to drive left and right running bodies by operating…
