Description
The Shivvers Circulator 2 Gearbox (PN 428E‑001A) is the OEM drive assembly used in Shivvers Circulator® drying systems to power the material‑moving components inside the bin. Engineered for continuous service in dusty, high‑load conditions, this gearbox provides synchronized output to one vertical auger and two sweep augers, ensuring steady grain circulation for even drying and improved test weight.
Built with a heavy cast housing, hardened gears, and sealed bearings, the 428E‑001A delivers the torque and reliability required for long drying runs. The unit features factory mounting points and a keyed output configuration for direct fitment on Circulator systems, simplifying replacement and minimizing downtime during in‑season repairs. Ideal for farms and service technicians maintaining legacy or current Shivvers installations.
Typical Uses
- Drives the vertical lift auger that returns grain to the top of the bin
- Powers two sweep augers that move grain across the drying floor
- Restores circulation performance in systems with worn or noisy gearboxes
