Raising and Lowering Openers
Negative Tongue Weight 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
draw bar and the safety chain is securely attached to tractor
before raising openers and unfolding drill.
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-4000/F/HD/HDF 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.
Each opener lift assembly has wire rod lock handle
,
and a cylinder lock status indicator
on the lock hook.
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.
