Expert Maintenance Review

To keep your grain handling system in top condition, we recommend a thorough inspection of the outer unloading auger flighting and the swivel assembly when replacing the outer tube.

Standard preventative maintenance for this assembly includes checking the tube for internal "polishing" or thinning at the high-flow discharge end. Replacing thinned tubes ensures an extended service life for the entire unloading assembly and prevents structural failure during a full tank discharge.
