An apparatus for combining planting implements enables an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. The apparatus is rigidly affixed to a conventional cultivating implement and comprises a support frame, a pair of brackets, and a connection bar. In combination, the support frame, pair of brackets, and connection bar provide a three-point connection whereby a conventional broadcasting implement may be attached thereto, thus enabling an operator of a tractor to use both a conventional cultivating implement and a conventional broadcasting implement simultaneously. In operation, at least a portion of the conventional cultivating implement is disposed behind the conventional broadcasting implement when the conventional broadcasting implement is attached to the support frame, thereby allowing simultaneous cultivation and broadcasting of constituents.

A vehicle connection guidance system may include a sensor and a controller. The sensor is configured to be supported by a vehicle having a first width and a connection interface, the connection interface having a second width different than the first width and along which multiple connection points lie, wherein the sensor is to output steering angle signals. The Controller is configured to output presentation signals based upon the steering angle signals The presentation signals are to generate a visual presentation of a projected path of the width of the connection interface to an operator of the vehicle.

A coupling device is disclosed which is designed as a hook with a hook body, an opening that allows the mating part of the attachment to enter the hook body, a guideway and a shoulder to counter any offset between the mating part of the attachment to the hook. Furthermore, the coupling device includes a locking latch that protrudes into the opening of the hook body and locks the mating part of the attachment in order to engage the mating part with the hook body, thereby retaining the mating part in a locked position. In an embodiment, the locking latch has a geometry that limits the motion of the locking latch and generates a motion curve. Furthermore, the locking latch moves on a motion curve to allow the locking latch to release the opening in order to allow the mating pan to enter the socket.

A work vehicle includes a first ground-engaging implement and a second ground-engaging implement connected to a chassis. The first ground-engaging implement moves within a first movement envelope with respect to the chassis, and the second ground-engaging implement moves within a second movement envelope with respect to the chassis. A lift arm is connected to the chassis and positioned between the first and second ground-engaging implements. The lift arm moves along a range of movement between a raised position and a lowered position. The lift arm is entirely positioned outside both of the first movement envelope and the second movement envelope within the entire range of movement between the raised position and the lowered position, such that the lift arm is permitted to move along the entire range of movement between the raised position and the lowered position without abutting the first movement envelope or the second movement envelope.

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.

Three-point hitch mount systems for connecting an implement to a tow vehicle having two lower hitch arms and an upper link arm are disclosed. The hitch mount systems may include a lift bar configured to be attached to the two hitch arms of the tow vehicle. The hitch mount systems may include a yoke assembly. The yoke assembly includes a forward-facing slot and a downward-facing slot for removably receiving the lift bar.

In a hydraulic adjustment device, preferably for transverse adjustment of the lower links of a three-point power lift on an agricultural machine, with two selectively controllable hydraulic cylinders and a hydraulic control circuit for actuating them, a control circuit with a pressure control device for generating an adjustable control pressure in dependence on an electrical control signal is provided, and a pressure-controlled changeover valve is connected to the pressure control device and, when a first control pressure value is applied, assumes a first switching position in which a first cylinder is connected to a pressure sink and the second cylinder is connected to a pressure source, and, when a second control pressure value is applied which is higher than the first control pressure value, assumes a second switching position in which the first cylinder is connected to the pressure source and the second cylinder is connected to the pressure sink.

A towed agricultural implement including a main chassis member, a moveable arm for carrying at least one working implement located to each side of the main chassis member, each moveable arm being moveable between a working position and a transport position, the main chassis member having a support device for attachment to a towing vehicle, the support device having left and right lower attachment points for attaching to lower mounting points of a three point hitch of a towing vehicle and a central upper attachment point for attaching to the upper mounting point of the three point hitch, in which each left and right attachment point is mounted on an articulated arm connected to the main chassis member, the main chassis member further including a regulating control apparatus to secure and release a free end of each articulated arm in an operative position. This construction has as an advantage that on encountering an obstacle the articulated arm can be released allowing the working implement to move away from the obstacle.

An attachment assembly for connecting an agricultural implement to a tractor. The attachment assembly comprises a tractor-side frame configured to extend from a rear of the tractor, and an implement-side frame configured to be removably attached to the implement. The implement-side frame is configured to rotate with respect to the tractor-side frame.

Agricultural vehicle (V) includes an operator's seat (S), a vehicular structure (C), a wheel support arrangement (100), a front bumper assembly (200), a position and draft control mechanism (30), a brake pedal linkage mechanism (500), a steering mechanism (600) and an exhaust device (700). The operator's seat S is configured to be provided in the vehicle (V) at at least one of a first seating position (Sf) corresponding to a first driving position, and a second seating position (Sr) corresponding to a second driving position, where the second seating position (Sr) is opposite to the first seating position (Sf). The vehicular structure (C) is configured to be moved between at least one lowered position in which each final drive housing (FH) is locked to vehicular structure (C) at corresponding first locking positions, and at least one raised position in which each final drive housing (FH) is locked to vehicular structure (C) at corresponding second locking positions.
