Real world solutions
"I've had great success with my Yetter Coulter cart, on which I mount 2995 series dry fertilizer coulters in front of my 12-tow semi-mounted planter. I mounted an air delivery system so I can auger fertilizer into one hopper rather than four boxes. I really like the convenience of one hopper, plus I get fertilizer placed off to the side of the row. The system is working well for me."
