主权项

1. A method of operation of a draper header including a feed draper and at least one side draper during comprising the steps of
pausing operation of the feed draper and the at least one side draper in the feed direction by controlling at least one control valve of a valve system of the draper header to divert flow from at least one motor configured to drive the feed draper and at least one side draper in response to operation of a crop processing mechanism of an attached harvester in the reverse direction; resuming operation of the feed draper by controlling the valve arrangement to return flow to the feed draper motor in the feed direction for conveying crop material in the feed direction in response to operation of the crop processing mechanism in the feed direction for a first predetermined period of time; resuming operation of the at least one side draper in the feed direction for conveying crop material in the feed direction toward the feed draper by adjusting the control valve to return flow to the at least one side draper motor in response to operation of the crop processing mechanism in the feed direction for a second predetermined period of time, longer than the first predetermined period of time; and wherein the operation of the feed draper motor and the at least one side draper motor is controlled using an accumulator and a control valve within the valve arrangement.
