I’m wanting to find a 2 row planter to use for no-tilling sunflower and soybeans. I have found a well used 2 row IH 800 planter that’s priced right. I’ve never used a planter but have a crude idea of the parts and how they work from researching online. If I go look at this one, what parts should I scrutinize to confirm it’s ready to use and not a money pit? Owner indicates it does need one chain replaced, which he will do before selling.
