operation 1 3 Leveling cultivator frame
The cultivator works best when the frame is
level and the hitch mast is perpendi cular to
the ground. The bottom of the frame should be ap-
proxi mately 28 inches from the ground when
cultivating.
On 1010 Tractor, screw left-hand lift link up
short and level culti- vator by adjusting
right-hand lift link.
Turn the adjusting arm on the center link
until the hitch mast is pe rpendieular with
the ground when cultivating.
Be sure cultivator frame always stops about 28
Inches from the ground when lowe red for
cultivation. This will give the rtgs space to
move and provide adequate crop clearance. See '
Control Lever,' ' page 11.
To level the cultivator frame, turn the
adjusting crank on each lift link until both ends
of the frame are the same helght above the floor
or ground.

Rig movement The rig coupler plates should be

crossarms
The clamp end ot the crossarm is 3/4 -inch longer
on one side than on the other side. LONG S I DE
RI G CLAR PS
za SHORT S I DE
The erossarms are installed with the short side
of the clamp up when holding straight shanks. The
cross - arms can be installed wi th the long
clamp side up to gain more ground clearance when
the ri gs are raised.
STRAICHT SHANK
When cultivating, shanks should De
perpendieular to the ground sweeps should
penetrate the soil to an equal depth and
erossarms should De set correctly for row
spacing and crop condition.
To posttton the shanks, loosen the nuts on top
of the rig clamps and move the crossarm and
shank until the ahank is perpendicular to the
ground. Tighten the nuts atter setting
0FF ET SHAN K
To move the crossarms left or right, loosen the
nuts on the bottom of the rig clamps. See row
spacing diagrams, pages 22-39 for erossarm
location. After positioning the crossar ms,
tighten the nuts.
When used with oftset shanks, the erossarm is
installed with the long side up.
Whereve r offset shanks are used on the cultivato
r, be sure the otf- set po rtion of the shank
angles in toward the rig pipe as shown
above. IMPORTANT E using spring- tooth
shanks, mWe sure there is elearanee between
spring tooth and erossarm b e h i n d it to
prevent spring-tooth trom hitting crossarin when
an obstruction is eneounte red.
To place the shanks at the s ame level, loosen
nuts on the clamps at the end of the erossarms.
Straight shanks should extend 1/2-inch above the
clamps, offset shanks 2 inches above the eIamps.
