Windrow Path Planning Using Harvester Tracks for Auto Baling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current agricultural systems lack efficient automated guidance for baling operations, particularly in navigating windrows of agricultural material, leading to suboptimal baling times and distances due to manual path definition and potential misalignment of baling machines with windrows.
Innovation Solution
An automated guidance system for tractors, utilizing location determining components and computing devices to analyze harvester travel paths and define optimized guidance paths for baling operations by identifying windrow locations and excluding previously harvested areas, allowing for precise steering and reduced travel distances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual path definition is used for baling operations, then operational flexibility is maintained, but baling time and travel distance are increased
Solution Approach 1:
The system performs preliminary action by using the harvester's GPS-tracked travel paths to pre-determine windrow locations and generate optimized baling paths in advance. This allows the baling operation to follow pre-calculated efficient routes rather than manually defining paths during the actual baling operation, thereby reducing baling time and improving productivity.
2Productivity
If automated guidance system is implemented, then baling time is reduced, but system complexity increases
Solution Approach 1:
The system applies self-service by having the harvester's existing GPS tracking system serve dual purposes: recording harvest paths and providing the data foundation for generating baling operation paths. This eliminates the need for separate complex path planning equipment, as the system utilizes data already collected during harvesting to automatically generate optimized baling routes.
3Measurement precision
If harvester travel paths are used to define windrow locations, then path accuracy is improved, but misalignment with actual windrows occurs in previously harvested areas
Solution Approach 1:
The system applies dynamics by making the path generation process adaptive rather than static. It dynamically evaluates each segment of the harvester's travel path to determine whether windrows were actually formed, excluding areas where the harvester was turning or operating on already-harvested ground. This dynamic filtering ensures that only valid windrow locations are used to generate baling paths, maintaining both accuracy and alignment precision.

AI summary
A system for windrow path planning comprises a tractor with an automated guidance system, and one or more computing devices for receiving harvester travel information, determining the locations of a plurality of windrows of agricultural material in an agricultural area from the harvester travel information, wherein determining the locations of the windrows includes assigning windrow locations to the one or more travel paths followed by the harvester only where the harvester was harvesting a crop. The one or more computing devices use the locations of the plurality of windrows of agricultural material to define one or more guidance paths for an agricultural operation performed on the windrows of the agricultural material. The automated guidance system of the tractor uses the one or more guidance paths to steer the tractor to follow the one or more guidance paths for the agricultural operation.
