Expert Maintenance Review
To keep your unloading system in top condition, we recommend inspecting the drive splines and flighting alignment during the installation of this extension.
Standard preventative maintenance for high-capacity unloading augers involves checking the outer tube for wear or thinning. Installing an auger extension provides an opportunity to ensure all drive components are operating efficiently, ultimately providing an extended service life for your John Deere® grain handling assembly.
