Tuscola, IL | Depending on the system, just how it’s wired. On the Trimble/caseih side, a single controller is only capable of doing 16 sections. So, on 24 row 30” planters or 31 row 15” planters, 2 rows are paired together so that only one controller is required. Every row has a clutch, but two clutches are activated at a time by the controller. They are just wired together, two clutches into the same port on the controller. Some guys have paired a second controller to do 24 individual rows or 31 individual rows. Typically, though shutting off two rows at a time gains enough control that a second controller doesn’t pencil out in seed savings. This depends a lot on your field shapes and sizes. It’s very rare to do all 31 rows of a 15” bean planter because the seed savings is less dollars and the overlap is less detrimental. Also, when you get up to the 24 row and bigger planters, it’s highly recommended that you are running highly accurate gps corrections such as rtk when doing individual row shutoff otherwise you can run into issues with the clutches shutting off when they aren’t supposed to because of gps drift and inaccuracies. Basically, with individual rows, it’s looking at a 30” section and 2 rows is a 60” section. The planter controller is deciding when to shut off the row based on the percentage of the 30” or 60” that’s inside of a previously covered area. This is adjustable, but typically set to shut off when 99% of the section is in an area of coverage. | |
