Industry-Specific Applications: Optimizing Every Agricultural Operation
Modern agriculture depends on accurate force and weight measurement to improve efficiency, reduce input costs, and maximize yield. VPG Force Sensors supports precision agriculture with proven sensing solutions across tillage, planting, harvesting, feeding, and material handling equipment.
Tillage Equipment & Draft Control Systems
Application Overview
Precision tillage is the foundation of successful crop production. Draft force measurement enables intelligent control systems that automatically adjust implement depth based on changing soil conditions, ensuring consistent field preparation while protecting equipment.
Industry Challenge
Soil resistance varies significantly across a field, causing inconsistent tillage depth, uneven seedbeds, excessive fuel consumption, and increased operator workload. Manual depth adjustments reduce productivity and accelerate drivetrain wear.
VPG Solution
VPG draft load pins provide real-time force feedback from tractor rear hitch arms, enabling automated draft control systems to maintain optimal working depth regardless of soil variability.
Proven Results
- Consistent tillage depth across the entire field
- Up to 15% fuel savings
- 23% increase in productivity
- Reduced drivetrain overload and maintenance costs
Typical Applications
Moldboard plows, chisel plows, disk harrows, cultivators, and subsoilers across all major tractor platforms.
Seed Drills & Precision Planters
Application Overview
Accurate seed placement is critical to achieving uniform crop emergence and maximizing yield potential. Force measurement enables precise control of downforce and real-time monitoring of planter performance.
Industry Challenge
Maintaining consistent seed depth across varying soil types, field contours, and planting speeds is difficult. Undetected row-unit malfunctions, blockages, or incorrect downforce settings lead to yield loss and wasted seed.
VPG Solution
Custom low-profile force sensors mounted on seed opener mechanisms continuously monitor row-unit downforce. Automated systems adjust pneumatic pressure in real time to maintain optimal seed depth while detecting blockages and mechanical faults.
Proven Results
