Adjusting High Speed Fertilizer Openers Down-Pressure-Tractors With Electro/Hydraulic Closed Center Systems

IMPORTANT: Adjust fertilizer opener down-pressure, as required, to keep openers in firm contact with soil, but DO NOT use more down-pressure than necessary or excessive wear and damage to machine could result.

A tractor with an open-center hydraulic system MUST BE equipped with Open Center Hydraulic Kit with Change Valve. (See your John Deere dealer for installation.)
