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
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 designed to supply
live hydraulic power to remotes.
On the standard 2S-2600 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 raised and locked up for folding,
transporting or for working under the drill.
Refer to Figure 17 and Figure 18
Each of the four opener lift assemblies has wire rod lock
handle , and a cylinder lock status indicator on the
lock hook.
 NOTE:
Opener transport lock handles move with openers
up or down, but locks only engage if openers are
raised completely or disengage if openers are
lowered completely. There are 4 assemblies, one on
each wing section near machine center (
Figure 18
),
and one on each gauge wheel ( Figure 17 ).
Lock Up Openers
1. Position opener transport handles in ROAD position.
2. Raise openers completely.
Lowering Openers
Refer to Figure 17
1. Position opener transport lock handles in FIELD
position.
2. Raise openers completely, to release locks.
3. Lower openers.
Machine Damage Risk:
Never lower openers with drill folded.
Negative Tongue Weight: 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.
