An agricultural mowing device that includes a tongue configured for connecting to an agricultural vehicle, a trail frame rotatably connected to the tongue about an axis of rotation, a first trail-frame wheel and a second trail-frame wheel each being rotatably connected to the trail frame, and a cutter bar connected to the trail frame. The cutter bar includes a front end and a back end. The mowing device also includes a transport system that has a transport frame rotatably connected to the tongue and a first transport wheel and a second transport wheel each being rotatably connected to the transport frame. In the transport position, the first and second transport wheels support the trail frame. The first transport wheel is radially closer to the axis of rotation of the trail frame than the front end of the cutter bar in the transport position.

An agricultural mowing device that includes a tongue configured for connecting to an agricultural vehicle, a trail frame, first and second trail-frame wheels, first and second lift actuators for lifting the trail frame, a trail-frame actuating mechanism operably connected in between the tongue and the trail frame and configured for rotating the trail frame, and a transport system. The transport system includes a transport frame, first and second transport wheels, and a transport actuating mechanism rotatably connecting the transport frame to the tongue. The transport actuating mechanism includes a transport actuator operably connected in between the tongue and the transport frame and configured for rotating the transport frame.

An agricultural mowing device that includes a tongue configured for connecting to an agricultural vehicle, a trail frame, first and second trail-frame wheels and a transport system. The transport system includes a transport frame rotatably connected to the tongue and rotatable relative to the tongue about a frame axis of rotation and first and second transport wheels for supporting the tongue in the transport position. The first transport wheel and the second transport wheel each being rotatable about a respective wheel axis of rotation, and each respective wheel axis of rotation is not parallel to the frame axis of rotation.

An agricultural header includes: a header frame; a cutter carried by the header frame; a steering assembly coupled to the header frame and including an axle; and a transport assembly coupled to the header frame. The transport assembly includes: a first arm coupled to the header frame and movable between a first transport position and a first operating position; a first wheel mount pivotably coupled to the first arm; a second arm pivotably coupled to the header frame and movable between a second transport position and a second operating position; a second wheel mount pivotably coupled to the second arm; and a linkage reversibly coupling the first wheel mount to the second wheel mount and coupled to the axle such that the second arm is movable independently of the first arm when the linkage is uncoupled from at least one of the first wheel mount or the second wheel mount.

A header for a crop harvesting machine includes front and rear wheel arrangements that pivot about respective upright axis between a field orientation and a perpendicular transport orientation, while having respective suspensions arrangements movable between different suspended heights. A biasing spring provides lift assist to carry weight of the wheel arrangement during adjustment of the suspension elevation while being isolated from the suspension once set at any one elevation. The front wheel arrangement includes an anti-rotation latch that locks the front wheel in the field orientation automatically upon disconnection of a hitch arm. A second wheel of the rear wheel arrangement can be held in a raised position relative to a first wheel in a field orientation. Load bearing surfaces between the suspended rear wheels and the header frame abut one another when latching to the header frame to isolate the suspension from the header frame in the transport orientation.

A system, for cutting a plurality of lawns, including: two or more robotic lawn mowers which each has a rechargeable energy storage, and a carrier, which includes: at least two holders, each of which is capable of retaining one of the two or more robotic lawn mowers, and two or more fences, each fence delineating an individual lawn of the plurality of lawns and configured to be operable while a respective of the two or more robotic lawn mowers is operating at the respective of the plurality of lawns.

A latch mechanism is used with agricultural equipment, such as a mower, for securing the header of the mower to the tongue during transport. A pivoting catch is mounted on the trail frame on which the header is mounted. A receiver for the catch is mounted on the tongue. During mower transport the catch is biased into engagement with the receiver by a first spring and secures the header to the tongue in a parallel orientation. When the mower configuration is changed to operational mode the catch is disengaged from the receiver using a second spring attached to the catch. A cable attaches the second spring to a wheel arm of a field wheel. Deployment of the field wheel into the operation mode draws the cable and second spring into tension, overcoming the biasing force of the first spring and pivoting the catch out of engagement with the receiver.

A system, for cutting a plurality of lawns, including: A) two or more robotic lawn mowers which each has a rechargeable energy storage, and B) a carrier, which includes: a) at least two holders, each of which is capable of retaining one of the two or more robotic lawn mowers and b) a charging system for the rechargeable energy storage. Also provided is the carrier as such and a method in which the system and the carrier can be used. The mowers are typically battery powered.

A transportable agricultural combine header includes a frame and a wheel assembly attached to the frame. The wheel assembly includes: (a) at least one spindle to which a wheel is configured to be mounted; (b) a rotatable arm connected to and extending from the spindle; (c) a frame attachment structure attaching the at least one spindle and the rotatable arm to the frame; and (d) a suspension system interconnecting the rotatable arm and the frame attachment structure for reducing stress on the frame as the agricultural combine header is transported.
