eSets are not available for 1991 and earlier models that have meter housing with two seed ports.
Your eSet system includes the eSet disk as well as these essential components: brushes and brush holders, a spring loaded singulator and a liner that contains the seed chute and baffle.
With the ProSeries meter version of eSet you receive this new hopper design. It reduces restrictions from the central fill hopper and eliminates meter overfill problems.
