Pre-Season Equipment Checklist for Spreaders and Sprayers
Before the first application of the season, your spreaders and sprayers need more than a quick once-over. A detailed pre-season inspection helps you avoid costly downtime, protects your inputs, and ensures your application is accurate from the very first pass.
Start with a Full System Inspection
Begin with a top-to-bottom visual check. Look for rust, cracks, worn metal, loose bolts, and signs of stress on structural components. Pay close attention to high-contact areas like hopper seams, frame joints, and mounting points. Winter storage can hide problems that only show up under load, so assume anything that looks questionable will become a problem in the field.
Chains, Bearings, and Drive Components
Chains should be properly tensioned and lubricated. If you notice stiff links or uneven movement, replacement is often the safer option heading into the season. Bearings should spin freely without noise or resistance. A failing bearing rarely gives much warning before it goes, and when it does, it usually takes other components with it.
Gates, Metering Systems, and Flow Control
Your gates control application rate, so they must operate smoothly and consistently. Check for corrosion, sticking, or uneven opening. Even small inconsistencies here can translate into significant variation across your field. Metering systems should be clean and free of buildup from previous applications. Residue can affect flow rate and accuracy.
Hopper and Tank Condition
Inspect the inside and outside of hoppers and tanks. Look for corrosion, pitting, or leftover material that could contaminate new product. For sprayers, check tank integrity, fittings, and seals. Even a minor leak can lead to product loss and safety concerns.
Calibration Readiness
Do not assume last year’s settings are still valid. Product density, humidity, and material composition all change from season to season. Plan to recalibrate before your first application. This step alone can protect both your yield and your input costs.
Electrical, Hydraulic, and Control Systems
Test all controls, sensors, and hydraulic functions. Verify that rate controllers, monitors, and flow systems respond correctly. Electrical issues are often small early on but can quickly become major disruptions during peak season.
Final Test Run
If possible, run your equipment briefly before heading into the field. Listen for unusual sounds, watch for uneven movement, and confirm everything is operating smoothly. A thorough pre-season check is not just maintenance—it is risk management. The more prepared your equipment is now, the more productive your season will be.
