Pre-Start Checklist
Raising and Lowering Openers
Opener sub-frames are on a dedicated hydraulic circuit.
Openers raise and lower independently of the drill frame
(which is raised and lowered by the transport lift circuit).
When lowered, the opener circuit can use live hydraulic
power to regulate down-pressure. To operate with live
hydraulic power, connect the opener lift circuit to the #1
remote hydraulic circuit or the circuit designed for
HYDRAULIC MOTOR control. On many CLOSED
CENTER or PRESSURE/FLOW COMPENSATED
tractors the #1 circuit is the circuit designed to supply live
hydraulic power to remote locations.
On the standard 3S-3000HD drill, the openers raise and
lower as a group, from a tractor cab lever. If the Point
Row Option is installed, each section can raise and lower
independently, using switches on the point row control
module in the tractor cab.
If the Two Outlet conversion kit is installed, a selector
valve near the hitch must be operated to switch between
Opener Lift and Transport Lift. During field operations,
this valve is in the Opener Lift position.
Opener Lock Up
The openers must be locked up for transporting or for
working under the drill.
Refer to Figure 14
Each opener lift assembly has wire rod lock handle
,
and a cylinder lock status indicator on the lock hook.
Note: Opener transport lock handles can be moved
with openers up or down, but transport locks only
engage after openers are raised completely and
disengage after openers are lowered completely.
There are two lock handles on each drill section, six
handles total.

Inflation Chart” on page 98.
❑ Check for worn or damaged parts and repair or
replace before going to the field.
❑ Check all nuts, bolts and screws. Tighten bolts as
specified on “Torque Values Chart” on page 97
Crushing Hazard:
Raising openers on unfolded, unhitched drill will cause drill
tongue to rise suddenly, which could cause serious injury or
death. Be certain that drill is hitched securely to your tractor
drawbar and the safety chain is securely attached to tractor
before raising openers and unfolding drill.
