Serena Il, Center of the Universe | I have a GP 1500 that I switched to parallel linkage units like a 1510. I set it up on 15" centers. It really improved the depth control. Part of the problem with a drill is too many down pressure springs. When it gets low on seed it had a tendency to lift the drill. The parallel linkage also really helps too. The reason that I did the conversion was cost. I couldn't justify a 15" planter. |
Drill or planter for soybeans
