Rear Steering:

Multiplanters with wheels fore and aft are able to fit rear steering rams and link into the tractor’s Global Positioning System (GPS) autosteer. For wider machines above 60 foot this steering system becomes highly recommended to avoid slope creep.

Interestingly, research shows that savings of up to 30% are available through the use GPS technology with a minimum of overlap, while some conventionally farmed land is as much as 17% double farmed.
