Operating Instructions
Lifting
The openers are raised and lowered on their own hydrau-
lic circuit. To operate them with live hydraulic power always
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 loca-
tions.
The openers can be locked up for transporting or for work-
ing under the drill. To lock the openers up, position the
opener transport lock handles in the ROAD position Fig-
ure 2-1 and completely raise the openers.
To unlock the openers, position the opener transport lock
handles in the FIELD position Figure 2-2 and completely
raise the openers to allow the opener transport locks to
disengage. There are two lock handles on each drill sec-
tion.

Folding
1. Folding is best achieved on level ground with the trac-
tor transmission in neutral. Be aware of the clearance
required to fold the drill.
!
CAUTION!
NEVER allow anyone near the drill during folding operations.
2. Position the opener transport lock handles in the
ROAD position Figure 2-1 and completely raise the
openers. The opener transport lock handles are
spring loaded and can be moved to the ROAD position
with the openers up or down, but the locks will only en-
gage when the openers are completely raised. There
are two lock handles on each drill section.
3. Make sure the transport lift cylinders and front box lift
cylinder are completely retracted.
