Controlled Track Paths for Reducing Soil Compaction in Fields
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Soil compaction and stand damage caused by agricultural machines significantly impact crop yields, particularly in crops like alfalfa and sod grass, with effects lasting for years and increasing over time, necessitating methods to minimize soil compaction.
Innovation Solution
Agricultural machines are guided to follow established track paths and adjust operations to minimize soil compaction by using control systems that include diverter mechanisms to form windrows with specific patterns and adjust the travel sequence to avoid wetter areas, ensuring engagement bodies follow existing tracks to reduce soil compaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If agricultural machines use heavier weights and larger engagement bodies to perform agricultural operations, then productivity and operational capability are improved, but soil compaction and stand damage increase significantly
Solution Approach 1:
The system records track paths of engagement bodies during initial field operations and uses this information to plan subsequent travel routes. By preparing the path plan in advance based on recorded data, the system enables machines to follow optimal routes that minimize soil compaction while maintaining operational efficiency.
Solution Approach 2:
The system continuously monitors the actual positions of engagement bodies during field operations and compares them against the planned track paths. This feedback mechanism allows real-time adjustments to be made, ensuring that machines stay on designated routes that minimize soil compaction while adapting to actual field conditions.
2Object-affected harmful factors
If agricultural machines follow established track paths to minimize soil compaction, then soil health is preserved, but operational flexibility and adaptability to field conditions decrease
Solution Approach 1:
The system dynamically adjusts travel paths by incorporating real-time position data and comparing actual routes against planned paths. The path planning is not static but adapts based on recorded track information from previous operations, allowing the system to optimize routes while maintaining soil health.
Solution Approach 2:
The system uses its own recorded track path data to generate future path plans, enabling autonomous optimization without external intervention. The machine learns from its previous operations and automatically adjusts subsequent routes to minimize soil compaction while maintaining operational effectiveness.
3Productivity
If multiple agricultural machines operate in the same field, then productivity increases, but soil compaction and stand damage accumulate and worsen over time
Solution Approach 1:
The system divides the field into specific track paths and assigns different routes to different machines or different passes. By segmenting the operational areas and using recorded track data to plan unique paths for each machine, the system distributes the mechanical stress across different soil areas, preventing cumulative compaction and stand damage while maintaining overall productivity.

AI summary
Methods and system for minimizing soil compaction relating to operations performed by agricultural machines. The agricultural machines can be guided so that at least one engagement body travels along an existing track path that was established by a prior travel of the same or different agricultural machine. Further, travel plans can determine the sequence in which the agricultural machine(s) travel in areas in the field so that travel on the track path(s) can be initiated in drier regions in the field. Operation of agricultural machines can also be adjusted to minimize deviations of other agricultural machines from existing track paths. For example, a windrower can operate a diverter to deposit a windrow at an offset location, and with a non-linear pattern, that may limit a baler from deviating from an existing track path while collecting crop material from the windrow, while also assisting in forming uniformly shaped crop bales.
