Adapter (27) of an agricultural implement, having a first, cylindrically contoured section (27a), the external diameter of which is designed to couple the agricultural implement to a US quick-hitch attachment system of an agricultural support vehicle, and having a second, spherically contoured section (27b), the external diameter of which is designed to couple the agricultural implement to a European lower-link attachment system of an agricultural support vehicle.

An agricultural vehicle combination including an agricultural tractor, which is operated using a main drive unit, and an ancillary drive unit, which is attached removably to the agricultural tractor by a three-point hitch, and which has an auxiliary axle that can be driven by an ancillary unit including at least one of a combustion engine and an electric motor.

A trolley that couples to a tow saddle is provided. The trolley includes an upper plate and a lower plate. The upper and lower plate are secured against a rear portion of a tow saddle. One or more support bars are coupled to the upper plate. The bars provide structural support for the upper plate and deflect a chain that transits apertures in the upper plate.

Agricultural implement having a tow bar device for towing the implement with a towing vehicle includes an implement part that trails the tow bar device mounted so as to be pivotable about a first pivot axis. The first pivot axis is parallel to a horizontal transverse axis of the implement. The trailing implement part and the tow bar device are coupled by means of at least one first actuator. The tow bar device, by means of the first actuator, is pivotable about the first pivot axis in such a manner that a tilt angle between the tow bar device and the trailing implement part is adjustable.

The present invention is directed to a self-locking non-backdrivable gear system. The gear system may comprise a primary motor input and self-lubricating gear box. The primary motor input is for rotation of the gearbox about the axis of a drive shaft. The gearbox may comprise an input ring gear, one or more planet locking gears, fixed spur gear, and output spur gear. In operation, rotation of the primary motor input causes rotation of the ring gear which causes rotation of the planet locking gear which causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, a rotational force applied to the output spur gear causes the gear teeth on the fixed and output spur gears to lock the planet gear in place.

This disclosure relates to systems and methods of towing, hitching, and connecting devices. In particular, this disclosure relates to tow devices, hitches, and connections for towing item containers behind vehicles, both autonomous and manually guided.

A coupling device of the type envisaged between a first vehicle (A) with at least two axes and a second vehicle (B) with at least two axes with the first vehicle (A) arranged to precede the second vehicle (B), in particular for the application to convoys of automatically guided vehicles, includes a hinge coupling section associated with the first vehicle (A) and a drawbar section associated with the second vehicle (B), connected to each other with the possibility of rotation through the relative distal sections. The drawbar section has an arc-shaped guide arranged horizontally in front of the second vehicle (B) to extend from the right side to the left side thereof, a slider sliding along the arc-shaped guide and a telescopic arm integral with one end of the slider and rotatably connected to the other end to the coupling section. The coupling device also advantageously include a steering assistance mechanism suitable for a redundancy of the steering members (S) of the second vehicle (B) by setting a steering angle which is a function of the position of the slider along the arc-shaped guide. The coupling device allows the automatic guide system to control the position and trajectories of the vehicles without any substantial exchange of forces through the device and enters into operation to allow the safe stop of the convoy when there are anomalies in the operation of the automatic guide system.

A garbage can hitch includes a base section, and a grab handle coupled to the base section. An attachment arm is coupled to the base section, and attaches to a garbage can. A receptacle is disposed within the base section, and configured to receive a hitch ball of a vehicle. A semi-cylindrical well is disposed within the base section, and configured to receive a handle bar of the garbage can. A garbage can includes a sidewall. The garbage can may include a built-in hitch attached to the sidewall. The built-in hitch includes a base section and a receptacle disposed within the base section. The receptacle receives a hitch ball of the vehicle. The gravity-enhanced configuration provides downward levered pressure on the hitch ball when the garbage can is towed, such that the hitch is kept securely linked to the hitch ball, even when the vehicle drives over bumpy or gravelly roads.

A hydraulic lifting mechanism for a large vehicle trailer comprises a square tubular metallic frame having a base and an upright support structure. A pair of pivoting wheels are disposed at a first base side of the base while a pair of wheels upon an axle are disposed upon a second base side of the base opposite the pivoting wheels. A four armed hydraulic lift is secured upon the upright support structure. At a distal end of the four armed hydraulic lift is a trailer hitch ball. The device is removably securable to a tractor.
