3. Operation
3.1 Beginning field operation
Following the completion of the assembly and pre-field
settings the machine can be attached to the rear seed
supply system. Refer to the provided information on the
supply system for setup and operational information on
that portion of the seeding system.
Enter the field and unfold the main/outer wings of the
machine. Pressurize the main lift hydraulic circuit to
sequence the main lift cylinders. Activate the transport lift
circuit, remove and store the channel locks. Fully retract
the transport cylinders. Pull forward with the air system
engaged and lower the machine into the ground.
3.2 Row Unit Operation
The Precision Shank Drill row unit follows the contour of
the ground with the parallel arm linkage system. Once the
frame height is set the rear packer tire controls the depth
of the seed boot. The hydraulic cylinder puts constant
down pressure on the packer tire and allows the shank to
pivot to the rear in event of an obstruction.
3.2.1 Adjusting Coulter Pressure
The coulter (1) cuts material and allows it to flow around
the shank (2) and boot (3) assembly. The spring assembly
applies constant pressure to the coulter blade.
The coulter depth can be adjusted by following the listed
steps:
1. Remove the 3/8" x 2-1/2" hex bolt (8)
2. Loosen the 5/8" jam nut (6)
3. Support coulter arm and blade from falling.
4. Loosen the 5/8" x 1-1/2" set screw. (5)
5. Arrange the spacers (7) on top & bottom of the coulter
arm to set the coulter to the proper height.
6. Install the busing with the thru hole (9) last on the
bottom.
7. Insert 3/8" x 2-1/2" hex bolt (8) and tighten the nut.
8. Tighten the 5/8" x 1-1/2" set screw (5) and jam nut.
