Durable, High-Capacity Box

The box is built for high capacity, yet has a simple and rugged design to withstand the heavy day-to-day use on larger livestock operations.

Twin Raised Auger

This unique design provides an even material flow to the discharge without the need for cross augers so that feed flow is consistent from the beginning to the end of the load.

Variable-Speed Control

The variable-speed drive includes an automatic high-speed cleanout feature to provide flexibility and control, and matches unloading rate to ground speed for proper feed placement in the bunks.

Spline Shafts & Sprockets

The splines allow a strong, reliable torque transfer, better sprocket alignment, and easier maintenance, while nylon-sleeve bearings provide longer life.

Swivel Discharge

The versatile swivel discharge will discharge to the left, right or rear of the Primor, allowing use in difficult-to-access areas. Controlled from the tractor, bedding can be blown up to 42’ through a full 300° range.
