Programmable function control for combine
First Claim
1. A combine system comprising:
- a chassis;
a header having a front portion for gathering a crop and operable to be movable between a lowered position and a raised position;
a lifting device connected between a chassis of said combine and said header and operable to lift said header from said lowered position to said elevated position;
at least one speed control device operable to control the ground speed of the combine;
a control signal connected to said lifting device and to said speed control device;
said control including a memory for raising and lowering said header using said lift cylinder and for adjusting the ground speed of said combine according to a programmed routine; and
an operator selection switch signal connected to said control and operable to commence said routine.

Abstract
A function management system includes a programmable control unit that can automatically coordinate combine traction functions and/or implement functions. In a learn mode, the operator performs a sequence of manual manipulations of the operator controlled traction and implement devices, and the control unit records and then stores information pertaining to the sequence of device operations. In an execute mode, the control unit automatically performs the sequence of device operations so that the sequence of operations occurs at the same intervals at which they were learned. As one example of a sequence, when the combine approaches the end of a field, at the touch of one button, the header is raised, the unloading auger is pivoted to an inboard position for safe turning, the ground speed is increased for rapid travel, the four wheel drive used during harvesting in the field is disengaged, the crop-processing implement speed, such as a rotor speed for a rotary crop-processing unit, is decreased, and steering of the combine is controlled to position the combine to the point of reentering the field. The sequence of device operations can be pre-programmed or input by the operator in the learn mode.

an operator actuatable learn/save switch signal-connected to the control;
wherein said control includes a learn mode, the learn mode being operable while the vehicle is moving, and wherein, in response to a manually triggered sequence of operations, including header positioning, the control stores the sequence of operations as stored instructions that are synchronized in memory with corresponding vehicle travel; and
wherein said control includes a replay mode, wherein the control automatically performs said stored sequence of operations synchronized with vehicle travel according to said stored instructions.

10. The combine system according to claim 1, comprising:
-
an operator actuatable learn/save switch signal-connected to the control;
wherein said control includes a learn mode, the learn mode being operable while the vehicle is moving, and wherein, in response to a manually triggered sequence of operations, including header positioning and changing of vehicle speed, the control stores information pertaining to the sequence of operations and stores information pertaining to distance intervals between operations with respect to the movement of the combine during performance of said sequence of operations; and
wherein said control includes a replay mode, wherein the control automatically performs said stored sequence of operations and wherein the operations of said sequence are performed with distance intervals therebetween which are substantially the same as that which occurred during operation of the learn mode, regardless of the speed of the vehicle.
