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.

An auto-leveling drive axle device for a wheel tractor, and leveling method. The device comprises a transmission device and a leveling device. The device of the present invention changes only a vertical position of a drive axle with respect to a wheel, and a wheel shaft distance and wheel center spacing are not changed, thus improving traveling stability of a vehicle.

A ballasting device for an agricultural vehicle includes a ballasting body, a first ballasting arm, and a second ballasting arm. The first ballasting arm is pivotally mounted on the ballasting body about a first bearing axis on one end and a first ballasting weight is arranged at the other end thereof. The second ballasting arm is pivotally mounted on the ballasting body about a second bearing axis at one end and a second ballasting weight is arranged at the other end thereof. The ballasting device includes a receiving device for receiving the ballasting device via a three-point hitch device of the agricultural vehicle. The first ballasting weight is adjustable by the first ballasting arm and the second ballasting weight is adjustable by the second ballasting arm.

A counterweight assembly for a work machine includes a structure, support studs, a first side wall, and a second side wall. The structure is coupled to a frame of the work machine and defines through holes, a first side end, and a second side end. The support studs are coupled to the frame and correspondingly received into the through holes to support the structure against the frame. The first side wall extends from the first side end and defines a first eyelet. The second side wall extends from the second side end and defines a second eyelet. A work machine guard rail is received between the first side wall and second side wall. One or more of the first eyelet and the second eyelet receive a lifting assembly for lifting the work machine, and the support studs transfer a lifting force from the counterweight assembly to the frame.

An arrangement for monitoring and or controlling the driving state of a self-propelled agricultural working machine comprising a variable-position interface for attaching an implement that is provided with a control device. Vehicle-specific data, a position signal regarding the position of the interface, and implement data regarding physical properties of an implement mounted on the interface can be supplied to the control device. The control device is operated to evaluate at least one the driving state of the working machine, taking into consideration the above-mentioned signals and data to control the working machine.

A counterweight assembly for a working machine comprising a counterweight having a mass for counterbalancing a working arm of the working machine, the counterweight comprising a mounting arrangement for the mounting of a heat exchanger thereon and defining an air flow path having an inlet and an outlet to permit air to flow through the heat exchanger when mounted thereon.

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 system for a bumper of a work vehicle includes a bumper interface. The bumper interface is configured to support a substantially downward load exerted by an attachment interface. The bumper interface includes a bumper pin retainer configured to retain a pin. The pin is configured to couple to the attachment interface. The pin is also configured to transfer the substantially downward load exerted by the attachment interface to the bumper interface. The bumper interface also includes a bumper anti-rotation feature configured to block rotation in a first direction of the attachment interface about the pin.

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.
