Which check is part of routine care for rotary spreaders to ensure proper operation?

• A. The hopper color matches the model
• B. The drive wheel operates without drag
• C. Calibrate the control knobs
• D. The spray nozzle is clean

Answer: (B)

The most important routine check is to make sure the drive wheel can rotate freely without any drag. When the drive wheel spins smoothly, it indicates the drivetrain and bearings aren’t binding, so the spreading mechanism will receive consistent power. If there’s drag, you can get uneven feed and areas that are over- or under-spread, plus added wear on the drive components. This simple test helps ensure the spreader operates reliably during use.

Cosmetic details like hopper color are not related to functionality, and calibrating the control knobs is about setting the application rate rather than confirming the mechanical operation. Spray nozzles are part of liquid spray equipment, not a rotary spreader.
