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 header support for supporting a header during road transport of an agricultural harvester. The header support has a header mounted to it in order to reduce a front axle load of the agricultural harvester. During harvesting, a support wheel of the header support is folded upwardly so it does not touch the ground during harvesting. The rotation axis of the support wheel extends in a substantially vertical plane during harvesting. This allows for a simple construction of the header support and reduces the vibration loads on the bearing of the support wheel during harvesting.

A system for installing and labeling lay flat irrigation pipe in flooded rice and furrow irrigated fields, and a trailer for laying a roll of pipe in an irrigated field. The trailer includes a flexible hitch assembly positioned at a first end of the trailer, wherein the hitch assembly couples the trailer to a vehicle. The trailer also includes a distribution assembly positioned at a second end of the trailer, wherein the distribution assembly includes a spindle and wherein the distribution assembly couples the roll of pipe to the trailer; and a gooseneck frame including a first end coupled to the hitch assembly and a second end coupled to the distribution assembly, with an upper member between the first end and the second end of the gooseneck, wherein the upper member of the gooseneck is elevated relative to the hitch assembly. The trailer may also include offset tandem wheels with a furrow assembly to facilitate the creation of a furrow ditch and for traversing flood irrigated levees for the purposes of installing lay-flat polyethylene pipe for irrigation. The trailer may also include an adjustable telescoping hitch to adjust to various vehicle hitch heights. The system includes a labeling system for indicating the punch size needed along the pipeline during installation. A computerized hole selection plan is developed and transferred to a microprocessor device, where sensors or a global positioning system is co-locate the device so the punch label can be applied along the pipe during installation.

An autonomous tractor for autonomously crossing farmland, includes one or more sensors for detection of an obstacle when crossing the farmland, and a central processing unit (CPU) for receiving input signals from the the sensors and for controlling movement of the tractor based on the input signals in order to avoid the obstacle, a coupler for coupling an agricultural machine able to be coupled to the tractor, and the agricultural machine includes one or more additional sensors for detection of the obstacle, wherein coupling of the agricultural machine operatively connects the additional sensors to the CPU and automatically provides data to the CPU regarding the location of each of the additional sensors on the agricultural machine and one or more specifications of each of these additional sensors.
