Wanting to upgrade planters this year. Have currently been using 6 row 7000 conservation planter and wanted to buy 12 row 1770 with liquid fertilizer but have not found one locally. I have found a 7200 liquid that might work but is a 1770 a better planter or not? The 7200 would be quite a bit less money I'm just wondering if I should keep looking or settle for the older planter?
