Disclosed is a work vehicle having a weight that can be attached to a vehicle body frame. The weight is attached in such a manner that, over an entire length in a front/rear direction of the vehicle body and in a vertical direction of the vehicle body, an upper end portion of the weight is disposed in a same position as or upwardly of a lower end portion of the vehicle body frame, and at the same time in a same position as or downwardly of an upper end portion of the vehicle body frame.

A tractor with a chassis comprising a drive unit, a drive gear, a drivable rear axle assembly, a front axle assembly and a front attachment assembly. The front axle assembly comprises an axle drive housing and two wheel suspensions mounted thereon, on which front ground engagement means is positioned. The tractor further comprises a cooling system for cooling the drive unit. The axle drive housing is arranged between the drive unit and the front attachment assembly viewed in the longitudinal direction of the tractor. The cooling system is arranged above the axle drive housing and, viewed in the longitudinal direction of the vehicle, completely between a front, vertically extending plane tangent to the envelope curves of the front ground engagement means in the straight-ahead position, and a rear, vertically extending plane which is tangent to the envelope curves of the front ground engagement means in the straight-ahead position.

A rollover prevention device couples a semi-trailer to a semi-tractor. The rollover prevention device comprises a top plate configured to be coupled to the semi-trailer and a bottom plate configured to be coupled to the semi-tractor. One or more frangible fasteners couple the top plate to the bottom plate. The rollover prevention device includes a controller coupled to one or more sensors, with the controller configured to determine a roll angle and a roll rate of the rollover prevention device. In response to determining the roll angle and/or the roll rate satisfy a rollover condition, the controller transmits a control signal to separable fasteners, which separate in response to the control signal allowing the top plate to detach from the bottom plate.

A work vehicle includes: an engine bonnet in a front section of a body of the work vehicle and forming an engine compartment, the engine bonnet being swingably openable and closable in an up-down direction of the body with an opening and closing axis extending in a width direction of the body in a rear section of the engine bonnet as a swing fulcrum; and a front guard covering a front portion of the engine bonnet and including a lower guard section fixedly supported by a body frame and an upper guard section supported by the lower guard section.

A computer-implemented method for detecting risk of upcoming tip-over for a vehicle is disclosed. The method includes acquiring (by processing circuitry of a computer system) normal force(s) of the vehicle, comprising a rear wheel normal force, and detecting (by the processing circuitry) risk of upcoming tip-over responsive to the normal force(s) fulfilling a normal force condition. The method may also include acquiring a pitch angle of the vehicle, and detecting the risk of upcoming tip-over may be further responsive to the pitch angle fulfilling a pitch angle condition. The method may also comprise causing a tip-over mitigation action to be performed responsive to detection of the risk of upcoming tip-over.
