You’ll need these spring clips to secure the Bullseye seed tube(Part # PPM700160) to the row unit on John Deere 1700 series planters(Model year 2007 and after). Deere seed tubes have a different mounting system and didn’t use the more secure pin method. So you will need to add these to your seed tube order if your planter row unit does NOT have pre-drilled holes for a pin and clip system. One package does 4 rows.
