Knockout wheel easily snaps into place

A seed knockout wheel is used to ensure that certain seed types are fully released from the seed opening of the vacuum seed disk. Wheel projections engage seed holes, forcing all seeds and foreign material to be ejected. The knockout wheel assembly is mounted inside the vacuum seed meter dome and runs against the backside of the seed disk.
 
A seed knockout wheel is required when planting with flat seed disks. There are three different types of knockout wheel assemblies available - sweet corn, sugar beet/sorghum, and edible bean. Each knockout wheel is designed to match the appropriate flat-type seed disk and is not interchangeable. Knockout wheels are shipped with the required seed disks when ordered with the planter or they can be purchased through the Service Parts.
Easy changeover

Easy changeover

Changeover of crops has never been easier. The knockout wheel and scraper features are now designed to be changed without the use of tools, just a simple snap into place. The design allows producers to install and remove these components in 15 seconds, saving 1 minute of time per row or five times quicker than before when switching crops.
 
Retrofittable domes make life easier for growers with equipment prior to model year 2015 planters.  The dome and knockout wheel/scraper can be ordered through parts to fit on MaxEmerge™ XP and Pro-Series™ row-units.
