Hitching Tractor to Planter

Do not stand or place any body part between planter and mov-
ing tractor. You may be severely injured or killed by being
crushed between the tractor and planter. Stop tractor engine
and set parking brake before attaching cables and hoses.
3-Point Hitching
Refer to Figure 3
The left arm
of the tractor 3-point hitch is secured and
prevented from shifting laterally. The right arm is
allowed to float on the pin.
The objective is to align the planter center-line with the
tractor center-line.
1. The planter includes several spacers to position and
secure the left arm of the 3-point hitch:
1 401-630H SPACER 3 PT 1 1/2 X 2
5 411-442D LOWER 3PT PIN SPACER 1/2 THK
2 411-448D LOWER 3PT PIN SPACER 1/4 THK
1 411-449D TUBE 3" X 1 1/2" X 1/2" LONG
2. The tube spacers ( and ) are always used, and
are typically positioned on the right and left of the
tractor hitch arm.
3. Insert open-end spacers ( and ) to the left of
the smaller tube spacer to achieve center-line
alignment. The following table has recommendations
for specific tractors.
4. Add a combination of the remaining spacers to elimi-
nate any slack space on the pin, and minimize side-
to-side play during operations.
5. Secure both sets of spacers with the provided
