The present disclosure relates to a vehicle, in particular an off-highway vehicle, comprising a first axle and a second axle and a sensor unit comprising at least one load sensor configured to produce a load sensor signal indicative of a load on at least one of the first axle and the second axle. The vehicle further comprises a movable weight configured to be moved relative to the first axle and to the second axle, an actuator system configured to move the movable weight relative to the first axle and to the second axle, and a control unit configured to control the actuator system based at least on the load sensor signal.

Provided is a work vehicle having an improved obstacle detection accuracy. The work vehicle includes: a bonnet provided on a front portion of a travelling vehicle body; an obstacle sensor that detects an obstacle on a front side; and a sensor attaching stay configured to extend toward a front side of the bonnet and to allow the obstacle sensor to be attached thereto.

A work vehicle includes: a body frame; a front weight at a front end portion of the body frame; a support mechanism supporting the front weight in such a manner that the front weight is movable in a front-back direction relative to the body frame; and a drive actuator configured to move the front weight in the front-back direction relative to the body frame between (i) a back position, at which the front weight is close to the body frame, and (ii) a front position, at which the front weight is far from the body frame.

An attachment assembly for use with a work machine includes an attachment adapter coupled to the work machine and fixed relative thereto and an attachment frame including a member defining an attachment point configured to engage, into an engaged mode, with the attachment adapter when a front suspension system of the work machine is raised to a raised position, and configured to disengage, into a disengaged mode, from the attachment adapter when the front suspension system is lowered to a lowered position, the attachment adapter configured to travel with the work machine when in the engaged mode and the disengaged mode, and the attachment frame configured to travel with the work machine when in only the engaged mode.

A counterweight mounting device, which is installed on a frame supporting a counterweight according to an aspect of the present invention, includes a first link of which a lower end is coupled to the frame so that the first link is rotatable about a first hinge shaft, a second link including a slot guide into which a second hinge shaft coupled to an upper end of the first link is inserted and in which the second hinge shaft slides, a hydraulic cylinder of which a lower end is coupled to the frame so that the hydraulic cylinder is rotatable about a cylinder rotation shaft and an upper end is coupled to the second hinge shaft and rotates the first link, and a connection member installed on an upper end of the second link and connected to the counterweight.

Ballast for operating machines, having a portion removably couplable to a hooking seat of the operating machine, characterized by having a fixed part is provided. The couplable portion, a movable part and means for constraining the movable part to the fixed part at a plurality of distinct distances (D, D′, D″) from the fixed part are provided, so as to change the center of gravity position of the operating machine.

Attachment assembly for use with a work machine. The attachment assembly includes an attachment adapter and an attachment frame. The attachment adapter is coupled to the work machine and fixed relative thereto. The attachment frame includes a member that defines an attachment point. The attachment point engages, into an engaged mode, with the attachment adapter when a front suspension system of the work machine is raised to a raised position. The attachment point disengages, into a disengaged mode, from the attachment adapter when the front suspension system is lowered to a lowered position. The attachment adapter travels with the work machine when in the engaged mode and also in the disengaged mode. The attachment frame travels with the work machine only when in the engaged mode.

An agricultural machine includes a vehicle body including a front wheel and a rear wheel, a hood at a front portion of the vehicle body, a protector provided to the vehicle body to protect an operator seat, and an obstacle detector to detect an obstacle, the obstacle detector being located in front of the protector outwardly in a width direction of the hood.

An agricultural machine includes a vehicle body including a front wheel and a rear wheel, an obstacle detector to detect an obstacle, and a position changer to change a position of the obstacle detector. The position changer moves the obstacle detector between a detection position that is a predetermined position to detect an obstacle and an evacuation position to evacuate from the detection position toward the vehicle body side. The position changer moves the obstacle detector to various detection positions allowing detection of the obstacle.

A support device, to be hooked up to a hitching device of a tractor: the support device includes a chassis 10 as a machine-welded metal structure which is fixed at 20 to the hitching device, and a platform extending cantilevered relative to the fixing device, the platform has an upper side 16 equipped at 160 to pre-position and center a box 40 to be supported on the platform, and a lower side 19 including at least one accommodating housing 191, 192 for cooperating with a corresponding protuberance 51, 52 of an add-on weight 50, intended to be supported under the platform to provide an anchoring in the shape of a dovetail type connection extending in the longitudinal direction substantially parallel to the direction of travel of the tractor.
