Section 2
Setup
This section covers preparing the drill hitch for tractor
hookup and hitching the tractor to the drill.
Hitch Requirements
Use the drill with category II or III tractors.
Models 1200, 1500 and 2000
These drills are factory set for category II tractors. For cat-
egory III tractors, switch the left- and right-hand pin
supports as shown in Figure 2-2.
In addition, you may need the following bushings (not sup-
plied by Great Plains) to fit your quick hitch or tractor 3-
point arms.
Upper link:1-in. ID x 1 1/4-in. OD x 2 1/8-in. max. long
Lower links:1 1/8-in. ID x 1 7/16-in. OD x 2 1/4-in. max. long

Category III Hitch
Models 1210, 1220, 1510, 1520 and 2010
These drills are equipped with extension brackets that
raise the drill 3 1/2 inches. This places the parallel-arm
and side-depth-control openers at the same height as the
coulters on the Center Pivot and All Seeds Hitches.
If the drill will not be used with a Great Plains hitch, remove
the extensions and install the standard pin supports. Pin
supports are stored inside the drill box. To remove the ex-
tensions, refer to Figure 2-3.
1. Remove the 1 1/8 x 2 1/2-inch hex bolt (1), washer (2)
and nut (3) from hitch plates and extension bracket.
