A working machine includes a traveling vehicle that is a first moving entity, a working device that is a second moving entity coupled to the first moving entity, and a sub battery loaded on the second moving entity to store an energy source to drive the traveling vehicle. Therefore, it is not necessary to newly provide a configuration to load the sub battery on the traveling vehicle, and a battery can be easily loaded. In a case where the traveling vehicle includes a main battery, the traveling and work can be continued according to a capacity of the sub battery without being stopped in order to charge the main battery that has a decreased remaining charge level.

An agricultural train assembly having a tractor and at least one implement coupled to the tractor through a tongue. The assembly has a tractor braking system that selectively applies tractor brakes, an implement braking system that selectively applies implement brakes, a controller that selectively applies the implement braking system, a sensor that communicates with the controller to identify a push force applied to the tongue, the push force being the amount of force applied by the at least one implement towards the tractor. Wherein, the controller communicates with the sensor to identify the push force and compares the push force to a push threshold and when the push force is greater than the push threshold, the controller instructs the implement braking system to apply a burst braking procedure.

An apparatus for operatively coupling a towable tool with a work machine via a three-point hitch includes a vehicle-side and a tool-side frame operatively coupled with a pivot bearing and a key-lock pairing. A biasing member is coupled with an configured to bias the tool-side frame relative to the vehicle-side frame.
