Hopper extensions are available for the Pro-Series row unit
seed hopper. These extensions are intended to be used with small-seed
crops like sugar beets that are not used in the CCS system or when
planting test plots with any seed. They provide additional capacity
for the small seeds and provide easier cleanout when changing crop
varieties on a frequent basis. The hopper extensions slide onto the
existing hopper and form a tight seal between the hopper and the extension.
A maximum of two extensions can be stacked onto the existing hopper.
