Cultivator Adjustments
These instructions apply only to implements in Cultivator
configuration.
These adjustments are typically made after setting
coulter height.
Sharp Object Hazard:
Be cautious when working near the cultivator. The edges of the
cultivator deflector blades may be sharp.
Refer to Figure 30
Cultivator Height
1.
Loosen the nuts at the lower shear bolts, and the
lock nut at the upper pivot bolt.
2. Slide the shank up or down to the desired height.
The factory setting is 10
1 ⁄
2
inches (26.7 cm),
measured from the bottom of the row unit frame to
the top of the sweep shank weldment.
3. Tighten the lower nuts and upper lock nut to
50 foot-pounds (67 N-m).
Note: If a lower shear bolt is ever failed by a field
obstruction, replace it with an identical:
802-720C HHCS 7/16-14X3 1/2 GR5 PLT
Do not use a higher grade bolt, or equipment
damage may result. Using a lower grade bolt may
result in nuisance shears.
Cultivator Pitch Angle
The upper cultivator mounting bolt
passes through a
slot in the shank , allowing some pitch angle adjustment.
The factory setting is maximum nose up.
Loosen both the upper and lower nuts. Adjust the
pitch angle. Secure both nuts.
Cultivator Deflector Height and Angle
The deflectors
are adjustable for height and angle.
To adjust the angle, loosen the nuts at the curved
slots. Move the deflector shields to the desired angle.
Re-tighten the nuts.
To adjust the height, loosen the nuts at the mount.
Slide the mount (which is slotted) up or down.
Re-secure the nuts.
To obtain further lowering, the shield mount may be
inverted.
