Operating Instructions
This section covers general operating procedures. It
assumes that setup items have been completed.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
General Description
Field operations are controlled by a tractor cab hydraulic
lever. When openers are lowered, a mechanical clutch
engages, and the left end wheel drives the seed meter
shaft.
Seed and fertilizer meters operate at a rate proportional
to ground speed, as set by sprockets and/or rate handle,
based on the rate charts, and calibration.
Seeding depth and furrow coverage are controlled by drill
down pressure and row unit setup.
Pre-Start Checklist

Escaping fluid under pressure can penetrate the skin causing
serious injury. Avoid the hazard by relieving pressure before

cardboard, NOT BODY PARTS, to check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. If an accident occurs, seek
immediate medical attention from a physician familiar with
this type of injury.
