Systems, devices, and methods for performing autonomous agricultural operations are described herein. An exemplary device may include a toolbar to which a plurality of implements may be interchangeably coupled, and a pair of parallel chassis beams mounted perpendicularly on the toolbar. At least a portion of each of the chassis beams may be telescopic and configured to be extended outward from, and retracted inward towards, the toolbar. The device may also include a plurality of drive assemblies each mounted on one of the chassis beams, and a plurality of motors corresponding to the drive assemblies and configured to drive the drive assemblies in accordance with one or more drive parameters to move the device throughout a site. The device may further include a computing device configured to automatically determine the drive parameters, and cause the plurality of motors to drive the corresponding drive assemblies in accordance with the drive parameters.

A track wheel for moving an object across a surface having a non-planar obstruction to allow smoother, easier and safer movement of the object over the obstruction. The track wheel has a track frame, a first wheel assembly, a second wheel assembly and a fluid-filled track assembly. The track frame interconnects the two wheel assemblies. The track assembly encircles the two wheel assemblies and frame in an endless loop manner. A mounting assembly connects the track frame to the object. The track assembly has a track link assembly and a pair of dampener tubes in the track link assembly. The track assembly passes into and out of a shield of the wheel assemblies that cleans the track assembly.

In one example, mobile industrial equipment for coupling to a truck for on highway transportation is provided. The mobile industrial equipment includes a frame to connect to the truck, a plurality of wheels connected to the frame, and a track assembly connected to the frame. In another example a method for using mobile equipment is provided. The method includes transporting mobile industrial equipment over the highway with a plurality of wheels connected to a frame of the mobile industrial equipment. The frame of the mobile industrial equipment is separated from the truck. The mobile industrial equipment is moved while separated from the truck using a track connected to the frame of the mobile industrial equipment.

A track hitching structure is for a wheeled crane and the wheeled crane, and includes a vehicle frame and a connecting cross beam. The first end of the connecting cross beam is connected with a track. The second end of the connecting cross beam is connected with the vehicle frame. The second end of the connecting cross beam is higher than the first end of the connecting cross beam. The vehicle frame is connected with the track by the connecting cross beam with one high end and one low end, so the long-distance force transfer from the track to the race of the vehicle frame can be handled, then the shortcomings of tedious structure, large size, large weight and the like of the connecting device caused by a horizontal connecting cross beam are avoided, and the reliability and the working performance of the entire crane are improved.
