A work vehicle includes: a chassis; a first axle carried by the chassis; a pair of first wheels rotatably coupled to the first axle; a first weight sensor associated with the first axle and configured to output a first weight signal; a second axle carried by the chassis; a pair of second wheels rotatably coupled to the second axle; a second weight sensor associated with the second axle and configured to output a second weight signal; and a controller operatively coupled to the first and second weight sensors. The controller is configured to: receive the first and second weight signals; determine a weight distribution of the work vehicle based on the received first and second weight signals; analyze the determined weight distribution to determine at least one recommended operating parameter; and output a recommendation signal based on the at least one recommended operating parameter.

The invention relates to a work machine (1, 1.1, 1.2) comprising: a work unit (2, 2.1, 2.2) or a receptacle (16) for a work unit, exactly one primary vehicle axis (3), wheel elements (4) arranged on both sides of the primary vehicle axis (3), drive units associated with the wheel elements (4), at least one control, wherein the control comprises at least one control circuit and effects a self-balancing of the work machine (1, 1.1, 1.2) about the main vehicle axis (3), and a counter-weight (5), wherein a position of the counter-weight (5) relative to the primary vehicle axis (3) is controllable via the control, and therefore the work machine (1, 1.1, 1.2) can be balanced about the primary vehicle axis (3) and controlled in the movement directions thereof via a position shift of the counter-weight (5).

A work vehicle and energy storage device include a ballast providing ballast weight to the horizontal end of the work vehicle, a stator of an electric machine having a vertically extending axis, a rotor of the electric machine fixed for rotation with the ballast and configured for rotation about the vertically extending axis, and a bearing supporting the ballast weight and the rotor for rotation of the rotor relative to the stator.

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 work machine may include an drive frame, a drivable track coupled to the drive frame, an idler wheel coupled to the drive frame to facilitate movement of the drivable track, and a wheel weight coupleable to the idler wheel. The wheel weight may be coupled to the idler wheel without removing the idler wheel from the drive frame.

Electric vehicles include adjustable battery positions and/or adjustable track widths for controlling vehicle stability. In some examples, an electric vehicle comprises a positioning mechanism configured to move the battery pack relative to the support structure (e.g., operable as the vehicle's frame) to change the vehicle's COG. The battery pack can be moved in response to other vehicle operations, e.g., COG changes caused by adding/moving loads, changes to the route grade, and the like. The battery pack can be slidably coupled to the support structure. In some examples, an electric vehicle comprises a track adjustment mechanism configured to move the vehicle's wheel axle relative to the support structure, along the wheel axle center axis, thereby changing the track width. The wheel axle can be coupled to a hub motor. In some examples, the battery is moved, and/or the track width is changed during the vehicle's operation.

A main ballasting weight (10) straight from the foundry for a farming tractor, comprising upper faces and lower faces (11, 12), two faces (13, 14) oriented transversely to the direction of movement of the tractor, and two lateral faces (15, 16) to parallel to the direction of movement of the tractor, said lower face comprising dovetail type means of connection (121, 122) to provide an anchoring with a secondary weight, said upper face forming an upper plate comprising a means of pre-positioning and centring (110) of a box (20) designed to be mounted on said main weight, said lateral faces (15, 16) being able to cooperate with lateral flanges (22, 23) of said box which are is attached bearing against said lateral faces and having fixation orifices (150) able to receive fixation screws cooperating with said lateral flanges for the fixation of said box to said main weight.

A method and system for assisting user selection of ballasting options for an agricultural vehicle when coupled to an agricultural implement. The user is presented with a selection menu of implement types, whereby each implement type defines operating ranges of discrete values for first, second and optionally third operational parameters of the vehicle, with the differing combinations defining a values subset. An optimal choice from the available ballasting options is made for each combination in the values subset, and a selection from the optimal choices based on prevalence or probability of occurrence is made and may be presented to the user. Operational parameters may include operating speed, loading due to implement weight and engine power.
