First Claim
Patent Images
1. A method of operation of a reel of an agricultural windrower, comprising steps of:
- providing a windrower including a fluid pump in connection with a signal controlled device for controlling a pressurized fluid flow to a reel of a header of the windrower for rotating the reel;
providing a programmable control module in connection with the signal controlled device and operable for outputting control signals thereto having variable signal values for controlling a speed of rotation of the reel; and
wherein the control module is programmed to operate in an automatic mode to automatically control the signal controlled device using a predetermined relationship between the signal values and the speed of rotation of the reel, wherein in the automatic mode the control module is configured to use the predetermined relationship to select a signal value corresponding to a desired reel speed as function of a ground speed of the windrower.

Abstract
An apparatus and method for varying the speed of a reel versus ground speed of an agricultural windrower, wherein a programmable control module in connection with a signal operated device operable for controlling operation of the reel, is programmed to operate in an automatic mode to control the reel speed as a percentage of the ground speed, while preventing the reel speed from falling below a minimum value.
