This invention relates to a device for harvesting long agricultural products and an agricultural self-propelled unit for harvesting agricultural products comprising the device.
This invention is thus applied in particular in the agricultural sector, in particular in the harvesting of products performed after the cutting (or mowing).
Harvesting devices, otherwise known as windrowers, are normally used for picking up from the ground grass, straw, hay (also cut by other machines) or for picking up pulses, as well as for picking up seed products, and, in any case, for picking up similar agricultural products, with a long shape.
Typically, these devices are equipped with a suitable movement carriage and are connected to a tractor or the like which pulls them, like a trailer, along a direction of forward movement.
These devices are equipped with an arm, generally extending in a curved fashion from the rear portion to the front portion, to allow the connection with the rear hook of the tractor keeping the device oriented correctly, that is to say, with the pick-up means facing the tractor.
Only in some cases, for the small-sized devices (that is, equipped with a single pick-up unit), there is the possibility of connecting them to the front portion of the tractor, which, however, must be set up for this application, with considerable costs to be borne by the user.
Moreover, it should be noted that this optional feature not may be acceptable for larger devices (that is, equipped with several pick-up units) since the visibility and driving problems would make it difficult to use the device.
In any case, from the above description it is evident that the prior art windrowers need a tractor for moving them, which represents a considerable cost for the user, especially if it is necessary to purchase a new pulling vehicle.
