Patent ID: 8291684

Claim:
A swather comprising: a tractor having ground wheels and a drive system for transporting the tractor in a direction of operation across ground carrying a standing crop to be harvested; a header attached to the tractor so as to be moved thereby over the ground for harvesting the crop; the header having a cutting knife arranged to provide a cutting action across a width of the header for cutting the standing crop; the header having a reel mounted above the cutting knife for rotation about a reel axis generally parallel to the ground and at right angles to the direction of operation such that bats of the reel pass over the cutting knife to carry the crop rearwardly of the knife, the reel being driven by a reel drive system; a convergence system rearwardly of the cutting knife for converging the cut crop into a swath for discharge from the header onto the ground; a speed control manually operable by an operator of the tractor for controlling a ground speed of the tractor so as to control a forwarding speed of the cutting knife over the ground; a header speed control system for controlling a speed of the reel; a header lift actuator for raising and lowering the header relative to the tractor; a reel lift actuator for raising and lowering the reel relative to the cutting knife; a reel location actuator for locating the fore and aft position of the reel relative to the cutting knife; and a header position control system for controlling the position of the header relative to the tractor and the reel relative to the header switch, the header position control system including: a first manually operable control switch operable by the operator for manually controlling the header lift actuator so as to move the header to a required position set by the operator; a second manually operable control switch operable by the operator for manually controlling the reel lift actuator so as to move the reel to a required height position set by the operator; a third manually operable control switch operable by the operator for manually controlling the reel location actuator so as to move the reel to a required fore and aft position set by the operator; and a crop-lodged switch operable by the operator; the crop-lodged switch being arranged when operated by the operator in a single switch action to carry out at least each of the following three functions: to actuate the header lift actuator to move the header, without the operator operating the first manually operable control switch, from the required position of the header to a predetermined lowered position in which the cutting knife is close to the ground; to actuate the reel lift actuator to move the reel, without the operator operating the second manually operable control switch, from the required height position of the reel to a lowermost position of the reel; and to actuate the reel location actuator to move the reel, without the operator operating the third manually operable control switch, from the required fore and aft position of the reel to a forward most position of the reel.
