Snake Line Windrow Formation Using Dynamic Rake Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural technologies face challenges in efficiently forming and preparing windrows from previously-cut crops, leading to uneven loading and inefficient pickup by balers or loader wagons.
Innovation Solution
An agricultural apparatus with crop engaging elements and a control unit that forms a snake line windrow on the field by engaging with previously-cut crops, allowing for improved windrow preparation and balanced loading.

1Productivity
If conventional windrow forming methods are used, then the windrow formation process is simple, but the loading becomes uneven and pickup efficiency decreases
Solution Approach 1:
The rake arms are made dynamically adjustable in position and angle through hydraulic or electric actuators controlled by a control unit. This allows the rake arms to adapt their configuration during operation to create the desired snake line windrow pattern, enabling improved pickup efficiency without requiring a completely fixed complex structure
Solution Approach 2:
A control unit receives input signals (either manually operated or automatically controlled) and adjusts the position and angle of the rake arms accordingly. This feedback control mechanism ensures precise formation of the snake line windrow pattern, optimizing loading uniformity and pickup efficiency while managing system complexity through intelligent control

AI summary
An agricultural apparatus for forming from previously-cut agricultural crop, such as grass or the like, a windrow on a field, which may comprise: a frame, crop engaging elements supported on the frame and configured to form from previously-cut agricultural crop a windrow on a field, and a control unit configured to control operation of the crop engaging elements. The control unit is further configured to provide control signals to the crop engaging elements in such a way that, in a windrow forming mode of operation, the crop engaging elements are driven to engage with the previously-cut agricultural crop, and form from the previously-cut agricultural crop the windrow which may have a snake line form on the field. Further detailed is a method for forming from previously-cut agricultural crop, such as grass or the like, a windrow on a field.
