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 for rotating the reel at a speed which is a 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.
