A frame of a work vehicle includes an upper plate that has a plate shape and that forms an upper surface of the frame extending along a front-rear direction; a lower plate that has a plate shape and that is opposite to the upper plate in an up-down direction and forms a lower surface of the frame; a vertical wall that is disposed between the upper plate and the lower plate in the up-down direction and connects the upper plate to the lower plate; and an attachment portion to which an actuator that moves work equipment in the up-down direction is attached, in which at least one of the upper plate and the lower plate includes a center portion, a first extension portion extending from the center portion, a second extension portion extending from the center portion, and a continuous portion connecting the first extension portion to the second extension portion.

A motor grader is disclosed. The motor grader may include an articulated implement. The motor grader may include an articulation control device. The articulation control device may be configured to determine that articulation motion of the articulated implement is occurring, for a threshold amount of time, in a second direction that is different from a first direction indicated by an articulation control command. The articulation control device may be configured to perform a response action based on determining that articulation motion of the articulated implement is occurring, for the threshold amount of time, in the second direction that is different from the first direction indicated by the articulation control command.

A plow conversion kit includes a frame having a pivot plate configured to attach to a vehicle and a frame pivotally attached to the pivot plate. A first actuator is attached to the frame. A pivot bracket is directly pivotally attached to the frame at a first pivot and to the first actuator at a second pivot. A mounting bracket is directly pivotally attached to the frame such that the mounting bracket is adapted to releasably attach to a work piece. A mount arm is directly pivotally attached to the mounting bracket and to the pivot bracket at a third pivot.

A working vehicle where a front axle case is supported by two front axle brackets includes a body flame formed by disposing beams at a prescribed interval, by welding reinforced plates to plate faces of the beams which face to each other, and by welding both end parts of one of the front axle brackets to the reinforced plates; and a front hitch formed by welding both end parts of the other front axle bracket to both end parts of a plate member which are bent. The front hitch is attached to the body flame such that the two front axle brackets are opposed to each other.

An attachment mount for the front end of a truck, which can fit trucks with full-width or tapering chassis. The attachment mount may include a front member for supporting a front-end truck attachment, and a distribution member. The distribution member may be attached to the vehicle chassis and to the front member, so that the attachment mount spreads stresses originating from downwardly-directed forces exerted on the front member by the attachment, to the front portion of the vehicle chassis.
