A hitch mounted forklift assembly includes a primary member that is insertable into a hitch receiver of a truck. A coupler is coupled to the primary member and the coupler is exposed when the primary member is positioned in the tow hitch. A lifting rail is provided that has a track gear integrated therein and a motor is coupled to the primary member. A drive gear is rotatably coupled to the motor and the drive gear engages the track gear in the lifting rail. The lifting rail is lifted upwardly or lowered downwardly by the drive gear when the motor rotates the drive gear. A cross member is coupled to the lifting rail and a plurality of tines is each from the cross member. The plurality of tines lifts and lowers a hay bale for transport.

A harvester system that includes a work vehicle. A harvester attachment removably couples to the work vehicle. The harvester attachment includes a tool bar. A quick connector couples to the tool bar. The quick connector removably couples and uncouples the harvester attachment to the work vehicle. A support system removably couples to the work vehicle. The support system supports operation of the harvester attachment.

A mower system comprising a powered mower, a connecting device connected to the powered mower and an attachment connected to the powered mower through the connecting device for conducting specified function during the operation of the mower system. The connecting device includes a mounting assembly mounted to the powered mower and a base rotatably mounted to the mounting assembly for driving the attachment being rotated together with the base in a horizontal plane relative to the powered mower. The utilization rate of the powered mower is effectively improved because other working functions can be conducted by the attachment which is connected to the powered mower through the connecting device.

An electric tractor including one or more all-electric bidirectional force exerting three-point hitch assemblies for lifting and lowering farm tool implements in level relationship to the ground regardless of the elevation of lift applied to the implement. The front, middle and rear three-point hitch assemblies are each operated using linear actuators. The hitches may be coupled with battery boxes to provide power and to counterbalance attached farm implements. Each of the described three-point hitch assemblies (including embodiments for front, middle and rear positions) may be operated through manipulation of electric controls. Electronic components include controller, displays, panels, wiring harnesses, linear actuators, joy sticks, lighting, switches, gauges, electric battery management system for managing one or more power sources, and processing modules and memory for controlling hitch movement and implements. The three-point hitch assemblies enable work in the front, middle and rear areas of the tractor.

A quick joint of a front loader, the quick joint includes: a coupling member (30) having a hook shape and pivotally connected to a first pivot point (P1) of a boom post (20) through a first pivot shaft (31); a spring member (32) for applying an elastic force in a direction of releasing the coupling member (30) from a coupling target shaft (14) disposed on a boom post support (10) which is attached to a tractor (1); a lock unit (34) having a part making contact with the coupling member (30), and provided with a lock pin (36) for restraining behavior of the coupling member (30) at a coupling position (A1); and a guide slot (38) having an arc shape and formed in the boom post (20) to define a moving path of the lock pin (36) when the lock unit (34) rotates.

A method for increasing the load on driving rear wheels (KB, KP) of a tractor during soil cultivation with a farm implement (2), attached to a three-point linkage (1) of the tractor. A vertical position of the attached implement (2, 20) is adjusted relative to the tractor by a position of the arms (4) of a lifting device and by adjustment of the length of the upper link (13) of the three-point linkage (1) of the tractor. After adjusting the length of the upper link (13), the axial force acting/induced in the upper link (13) is determined and during travel of the tractor is continuously monitored and automatically maintained at the adjusted value. Also the adjusted vertical position of the implement (2) attached to the tractor is continuously monitored (2) and is automatically maintained at the adjusted value, thereby maintaining the vertical position of the attached implement (3) in this regulation and thus also constant ploughing depth.
