Halfbalecotton - 1/28/2021 21:32 What all do I need to run a 20/20 monitor with my 1770 planter( I'm planning on buying all used components)? I only want to use the 20/20 to monitor seed population/ spacing and possibly use it for row shut offs. I have a 2630 screen for autosteer (currently sf1 but will upgrading to sf2 next year) and computertrak 250 for a planter monitor.
