Corrosion Resistant Materials

Every Willmar spreader is designed with corrosion-resistant phenolic flooring so material moves smoothly, reducing build-up and extending the life of the conveyor chain.

A powder painting process enhances the overall protection of Willmar equipment. Once paint is applied, equipment goes through a quick cure oven that bonds the powder paint to the steel for a high-quality, durable finish that protects and extends the life of the spreader.

Consistent Conveyor Systems

Depending on the model, Willmar spreaders are equipped with a two-speed conveyor belt that provides an application rate of less than 100 lbs. per acre to over 2,000 lbs. per acre. The chain and sprocket conveyor ground drive system maintains a consistent relationship between ground speed and conveyor speed insuring precise application of materials even in moist condition. A slip clutch sprocket assembly is incorporated to prevent damage to drive components.

Equal Load Distribution

A multi-leaf, spring suspension system with rocker arms positioned on both sides of each axle reduces bounce, improves stability and provides a smooth ride for a consistent spray pattern. The suspension system allows you to unhook from the spreader without the risk of tilting or tipping over.

Accurate Spread Pattern

Willmar spreaders are available in single- or dual-spinner configurations. The single spinner has a 65-ft. (19.8 m) total spread pattern width using a single-pass, flat-type pattern which helps reduce the number of passes across a field for more economical operation.

Dual-spinner models are available with 40- (12.2 m) or 50-foot (15.2 m) that delivers an 80- or 100-foot spread, respectively, that creates a pyramid-style spread pattern with 100% overlap which reduces spread pattern variations due to wind and rough terrain.
