Assembling Center Pivot Hitch
Refer to Figure 1.
1. Unstrap the transport tires (1) from hitch. Assemble
tires to outer hubs with 1/2-by-1-inch lug bolts (2).
2. Center coulter toolbar assembly (3) under hitch (4)
and fasten to upper coulter-toolbar support with 5/8-
by-8-inch bolts (5), flat washers (6), lock washers (7)
and nuts (8).
NOTE: Use extra care when assembling coulter toolbar to
hitch. It is critical that coulters are centered under center
pivot hitch for proper tracking with drill. A 12-foot hitch with
7 1/2-inch row spacing is the only unit with a coulter at the
center of hitch. All other coulter toolbars will have a gap at
the center of hitch.
3. Bolt hose loop (9) onto a coupler nut welded near front
of hydraulic tongue (10). Use a 1/2-by-1-inch bolt (11),
two flat washers (12) and a lock washer (13).
