Abstract
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.

A method for operating an agricultural mowing assembly, comprising:
- configuring an agricultural mowing device to be towed behind an agricultural vehicle, the agricultural mowing device being configurable in a field position for cutting a crop material in a field and a transport position for transporting the agricultural mowing device, the agricultural mowing device comprising a tongue configured for connecting to the agricultural vehicle, a trail frame rotatably connected to the tongue, a cutter bar connected to the trail frame and configured for cutting the crop material in the field position, a first trail-frame wheel and a second trail-frame wheel each being rotatably connected to the trail frame and configured for supporting the trail frame in the field position, a first lift actuator operably connected in between the trail frame and the first trail-frame wheel and a second lift actuator operably connected in between the trail frame and the second trail-frame wheel, and the first lift actuator and the second lift actuator being configured 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 comprising a transport frame, a first transport wheel and a second transport wheel each being rotatably connected to the transport frame and configured for supporting the tongue in the transport position, and a transport actuating mechanism rotatably connecting the transport frame to the tongue, and the transport actuating mechanism comprising a transport actuator operably connected in between the tongue and the transport frame and configured for rotating the transport frame;
- positioning the agricultural mowing device in the transport position by:
- rotating the transport frame, by the transport actuator, from a retracted stowed position to an extended support position wherein the first transport wheel and the second transport wheel support the trail frame;
- and
- rotating the trail frame, by a trail-frame actuator, about an axis of rotation such that the trail frame is substantially aligned with the tongue for reducing an overall width of the agricultural mowing device;
- and
- positioning the agricultural mowing device in the field position by:
- rotating the trail frame, by the trail-frame actuator, about the axis of rotation such that the trail frame is substantially perpendicular to the tongue for increasing the overall width of the agricultural mowing device;
- and
- rotating the transport frame, by the transport actuator, from the extended support position to the retracted stowed position wherein the transport frame is located above the trail frame.
