A vehicle sink alert method and system that includes collecting image data, determining field conditions, calculating wheel sink depth, predicting vehicle sink events using wheel sink depth and field conditions, and activating an alert when a vehicle sink event is predicted. The method can include predicting vehicle sink events using GPS coordinates and historical vehicle sink data. The method can include determining and using vehicle motion to predict vehicle sink events. Predicting vehicle sink events can include forming a multi-dimensional model with positive sink points where vehicle sink events have occurred and negative sink points where vehicle sink events have not occurred; generating a current vehicle point using monitored and calculated data; determining whether the current vehicle point is within a positive sink region formed by the positive sink points; and predicting a vehicle sink event if the current vehicle point is within the positive sink region.

A soil apparatus (e.g., seed firmer) having a locking system is described herein. In one embodiment, the soil apparatus includes a lower base portion for engaging in soil of an agricultural field, an upper base portion, and a neck portion having protrusions to insert into the lower base portion of a base and then lock when a region of the upper base portion is inserted into the lower base portion and this region of the upper base portion presses the protrusions to lock the neck portion to the upper base portion.

In a kit comprising a self-propelled two-track stilt vehicle and a transportation trailer, a lifting device, braced on the trailer, is provided that acts on central elements of the running and carrying structure of the stilt vehicle. The running and carrying structure of the stilt vehicle having four wheels comprises, oriented transversely relative to the travel direction, front and rear transverse structures, on which two stilt structures respectively having a wheel-carrying unit that carries at least one wheel are disposed on both sides at the end. The transverse structures are constructed in multiple parts having a middle piece and left and right end pieces, which can be fixed in various width positions. The stilt structures are constructed in multiple parts having primary parts connected to the associated end piece of the transverse structure and secondary parts, fixable thereon in various height positions and on which associated wheel-carrying units are disposed.

The invention pertains to the peculiar mode of mechanism of multiple integral chassis weight in agricultural machinery and implements, by equalizing the weight of the heavyweight chassis to the lightweight one, ensuring an even distribution of the machine weight on the wheels assemblies, providing perfect and uniform copying of terrain unevenness.

The invention is characterized by the proper use of pneumatic springs (1), installed slant (2), through specific fixing brackets (3) and (4) respectively, to the heavyweight chassis (5) and to the lightweight one (6), and such springs (1) own a technical feature that, when pneumatically driven, they apply some force between the chassis (5) and (6), which they are interconnected to, and transfer the weight of the heavyweight chassis (6) to the lightweight one (5) by reaction, equalizing the weight between them both and the machine weight is transferred to the wheels. Such springs (1) can work independently, interconnected, as a closed system or as an active system.
