4. If the hitch frame is not level, remove or replace spac-
ers (1) from transport-lift-cylinder rods until hitch is
level. See Figure 3-3.

Coulter Mounting Height
You can change the depth of individual coulters by adjust-
ing coulter-mounting height. If you adjust coulter height,
be sure to rebolt coulters vertically straight and correctly
spaced. To raise or lower individual coulters:
1. Loosen mounting clamps and adjust coulter to desired
height. Do not lower coulter spring bar below top u-
bolts on coulter clamp.
2. To re-tighten clamps, refer to Figure 3-4. Snug hex-
head clamp bolts (1) just until u-bolts are tight on each
side of spring bar.
3. Tighten nuts (2) on u-bolts.
4. Finish tightening hex-head clamp bolts.

NOTE: Even when coulter is held securely, there may be a
gap between clamp halves.
Coulter Down Pressure
Added Weight
In hard soil conditions where coulter penetration is limited,
you can add suitcase weights to the weight brackets on
the hitch. You can add up to 567 kilograms (1,200 pounds)
to the front brackets. Place an equal amount of weight on
the right and left side to balance the weight distribution.

Weight Brackets
Coulter Springs
Coulter-spring length is preset at the factory to 254 mm
(10 inches), giving coulters an initial operating force of 181
kg (400 pounds). This setting is adequate for many difficult
no-till conditions. For lighter no-till conditions where rocks
or other obstructions are a problem, you can reduce coul-
ter down pressure to give coulters better impact
protection. Refer to the following chart for adjusting coulter
down pressure.
NOTE: Do not reset coulter-spring length shorter than
248 mm (9 3/4 inches). Shortening springs more than 248
mm (9 3/4 inches) may contribute to premature failure of
parts and warranty will be voided.
