Assembly and Setup
Prestart Checklist
Depth Sensing Wheel
If your Precision Hitch is equipped with liquid fertilizer
(PFH), the fertilizer drive wheel doubles as the coulter
depth sensing wheel and will require additional sensor as-
sembly and adjustment.
If you do not have the liquid fertilizer option (PFH), the
coulter command will contain a coulter depth sensing
wheel which is subassembled and preadjusted.
Check
All major frame components
Fasteners and pins that were shipped with the Coulter Com-
mand System.
NOTE: All hardware from the factory has been installed in the
location where it will be used. If a part or fastener is temporarily
removed for assembly reasons, remember where it goes.Keep
the parts separated.
Have a minimum of 2 people at hand while assembling the
Coulter Command System.
Have a forklift or loader along with chains and safety stands
ready for the assembly task.
If you are unsure where a fastener is used, refer to the Parts
Manual to identify it.

See Figure 1-1.
Install the coulter depth sensing wheel assembly (1) to the
front 4” x 4” coulter tool bar tube with the two 5/8 x 6 inch
u-bolts (2), lock washers (3) and nuts (4).
Position the center of the coulter depth sensing wheel
mount bracket 2 1/4 inches to the right of the center of the
Precision Hitch beam. This will leave about 2 3/4 inch
clearance between the inside of the depth sensing tire and
the edge of the hitch center beam.
