DEERE & COMPANY has secured a major milestone in agriculture with a newly patented system for precision planting. This innovation focuses on U.S. Patent No. 12894567, titled ‘Row unit overlap avoidance system and method’. The patent describes an agricultural planting system comprising an implement configured to be coupled to a work machine, row units of the implement, and first and second pairs of wheels configured to pivot and rotate to facilitate a turning operation during forward travel of the planting system.

Precision Turning and Row Alignment

The row units are arranged in first and second ranks depending on their forward-aft placement. Furrow openers of the first rank of row units are configured to contact the ground along a first contact line, and furrow openers of the second rank of row units are configured to contact the ground along a second contact line. During a turning operation, the implement turns about a turning center axis, and the first and second pairs of wheels pivot in opposite directions, which allows the first and second contact lines to remain equidistant from the turning center axis during the turn.

Swanson Reed Patent of the Month: Agriculture, Farming and Fishing

This invention stands out as a masterpiece of mechanical synchronization within the high-stakes world of precision agriculture. By solving the geometric puzzle of maintaining equidistant contact lines during a turn, Deere & Company has addressed a persistent inefficiency where dual-rank implements often struggle with inconsistent seed placement and overlap. This level of technical sophistication ensures that every square inch of a field is utilized with surgical precision, regardless of the complexity of the machine’s path. It is a fundamental shift in how we approach the physics of the field.

Winning Swanson Reed’s Patent of the Month highlights the significant leap forward in implement maneuverability. Traditionally, turning large agricultural equipment leads to “pinching” or “fanning” of row units, causing over-seeding or skipped sections. This patent’s unique wheel-pivoting logic effectively eliminates these errors, setting a new standard for equipment design in the farming industry. It represents a transition from simple mechanical towing to intelligent, responsive hardware that actively compensates for the dynamics of a turn. This ensures that the second rank of units follows a path that is perfectly harmonized with the first.

Furthermore, the environmental and economic implications of this technology are substantial. By preventing row unit overlap, farmers can drastically reduce the unnecessary consumption of expensive inputs like seeds, fertilizers, and pesticides. This optimization directly contributes to more sustainable farming practices while simultaneously boosting the bottom line for producers. It is a rare example of an innovation that provides immediate practical value while pushing the boundaries of what is possible in large-scale agricultural engineering, making it a well-deserved recipient of the Patent of the Month award for April 2026.

U.S. R&D Tax Credit Eligibility

To qualify for the R&D tax credit in the United States, an activity must generally meet the Four-Part Test. Deere & Company’s development of the row unit overlap avoidance system aligns with these requirements through the following criteria:

• Technological in Nature: The development process relied on principles of mechanical engineering, geometry, and computer science to design the pivoting wheel mechanisms and control logic.
• Permissible Purpose: The primary goal was to improve the functionality and performance of agricultural implements by eliminating overlap and enhancing precision during turns.
• Elimination of Uncertainty: Engineers faced technical uncertainty regarding the optimal pivoting angles and the mechanical configuration required to keep dual contact lines equidistant from a moving turning center.
• Process of Experimentation: The team likely utilized CAD modeling, kinematic simulations, and physical prototyping to evaluate various wheel configurations and control algorithms before arriving at the final design.

Practical Applications for R&D Tax Credits

1. Development of Automated Control Software: Designing and testing the software algorithms that interpret turning radius data and command the wheel actuators to pivot in opposite directions is a clear R&D activity involving computational modeling and the elimination of technical uncertainty.

2. Integration of High-Stiffness Materials: Researching and testing new alloy compositions or composite materials for the row unit ranks to withstand the mechanical stresses of pivoting while maintaining precise ground contact falls under material science experimentation.

3. Kinematic Simulation for Variable Soil Conditions: Conducting simulations to determine how the pivoting wheel system performs across different soil densities and moisture levels to ensure the equidistant contact line logic remains valid in real-world environments constitutes a systematic process of experimentation.
