Northeast Indiana (Auburn) | If you have high speed sensors they will count seed. If you don't have a radar or GPS on your tractor you can use a gear tooth sensor to get your speed if your monitor has a radar plug. www.agri-tronix.com is another source for info. If the drill harness is a John Deere made for a John Deere monitor you may have to either change some pins in your monitor plug or get an adapter plug. |
