Operating Instructions
This section covers general operating procedures. It
assumes that setup items have been completed for both
drill and tractor.
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
On the standard 3S-4000HD/HDF, field operations are
controlled by tractor cab hydraulic levers. When openers
are lowered, mechanical clutches engage, and the
gauge wheels drive the seed meter shafts. Markers, if
installed, are on a separate circuit.
If the Point Row Option is installed, openers are
controlled by section, and are raised and lowered by
solenoid valves operated by the point row controller.
Seed meters operate at a rate proportional to ground
speed, as set by Drive Type and Seed Rate Handles,
based on the Seed Rate charts, and calibration.
Seeding depth and furrow coverage are controlled by drill
down pressure and row unit setup.
