Abstract: A work vehicle includes a link mechanism to be equipped with a work implement, a drive mechanism to drive the link mechanism to ascend and descend the work implement, and a control lever is to be operated to ascend and descend the work implement. The work vehicle includes a first displacement transmission mechanism, an additional operational mechanism, and a second displacement transmission mechanism. The first displacement transmission mechanism links the drive mechanism and the control lever to transmit a displacement of the control lever to the drive mechanism. The additional operational mechanism is configured to operate the control lever at a location apart from a position of the control lever. The second displacement transmission mechanism mechanically links the additional operational mechanism and the control lever without interposing the first displacement transmission mechanism to shift the control lever in accordance with an operation of the additional operational mechanism.

Abstract: Methods of attaching cutting elements to earth-boring tools, comprising abutting a portion of a cutting element against at least one surface of an earth-boring tool with a braze material disposed therebetween; and brazing the cutting element to the earth-boring tool by applying high-frequency vibrations to cause the braze material to become flowable. Methods of securing cutting elements to earth-boring tools may comprise at least partially coating a cutting element with a braze material. The cutting element may be at least partially disposed in a pocket formed in a body of an earth-boring tool with the braze material adjacent surfaces defining the pocket. The cutting element and the braze material may be ultrasonically torsionally oscillated to braze the cutting element within the pocket.

Abstract: An improved power control device including a pair of remote levers having lower ends provided with pivot structure for pivotally attaching the remote levers to the support platform of a power tool attachment. A pair of rigid bars are pivotally coupled to the remote levers and extend rearwardly and are pivotally coupled to the power control levers of the vehicle. Thus, movement of the remote levers by a control operator at the power tool attachment causes corresponding movements of the power control levers of the vehicle so that the vehicle can be controlled by the operator on the power tool attachment. The pivot connections between the bars and the levers and between the remote levers and the platform of the power tool attachment can be quick-release fastener units.
