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 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 working vehicle has a ballast weight system including a fulcrum mounted on the vehicle frame and a ballast weight configured to pivot between a mounting configuration with the ballast weight is resting on the ground and an operational configuration with the ballast weight is carried by the vehicle frame. The ballast weight has a mounting arm and a lower corner portion. The mounting arm has a recess configured to interact with the fulcrum, wherein in the mounting configuration, the recess faces sideways such that the work vehicle is driven towards the ballast weight until the fulcrum interfaces with the recess. A catch mechanism secures the ballast weight to the fulcrum. A lift mechanism attaches between the ballast weight and the vehicle frame such that the lift mechanism pushes on the corner portion to pivot the ballast weight about the fulcrum. A latch mechanism pins the ballast weight in the operational position.

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.

A working vehicle has an undercarriage assembly configured to drive the working vehicle over ground and a chassis connected to the undercarriage assembly through a suspension system. The suspension system includes a mechanical spring, the mechanical spring having a first end connected to the undercarriage assembly and a second end. The suspension system includes a hydraulic cylinder, the hydraulic cylinder having a first portion that mounts to the second end of the mechanical spring and a second portion that connects to the chassis such that the mechanical spring and hydraulic cylinder are arranged in series between the undercarriage assembly and the chassis to modify the height of the chassis. The suspension system is configured to level the chassis to offset the effects of ballast weights or other external loads such as from a drawbar or 3-point hitch.

Vehicles having the versatility to be used as farm vehicles while also being able to be used as a transportation method, such as a motorcycle, are provided. The vehicles can generally include a three-wheel configuration in which first and second drive wheels are substantially vertically aligned, and the third wheel is offset from the vertically aligned drive wheels. The third wheel can be aligned with the second wheel, or it can be disposed at a location that is between the first and second wheels while still being offset from the vertical alignment. A tool for performing farming actions is also provided. In some instances the tool can be laterally offset from the vertically aligned wheels, located between the drive wheels, while in other instances the tool can be disposed distal of the rear wheel. Many vehicle and tool configurations are disclosed, as are methods for operating the same.

A front perception module is utilized in conjunction with a front ballast system, which is included in a work vehicle and which has a laterally-extending hanger bracket supporting a number of removable ballast weights. In various embodiments, the front perception module includes an environmental depth perception (EDP) sensor system including a first EDP device having a field of view (FOV) encompassing an environmental region forward of the work vehicle, a mounting base attached to the work vehicle, and a front module housing containing the EDP sensor system and joined to the work vehicle through the mounting base. The front module housing is positioned over and vertically spaced from the laterally-extending hanger bracket in a manner enabling positioning of the removable ballast weights beneath the front module housing.

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.
