LIFT ARMS, TINE TUBES AND TINES
Referring to figures 15, 16 and 17, position all lift arms and secure in place with two 1/2 x 7-1/2” bolts, lockwashers and nuts.
Lift arm spacing is determined by referring to legend and schematic of respective model represented in Fig. 17.
NOTE: Special lift arms are used where hydraulic cylinders are located. These special lift arms are left or right
handed (Fig. 15)
Tine tubes should be assembled to lift arms as shown in Fig. 15. Secure tube bushings in place with four 7/16” x 1” bolts,
lockwashers and nuts. See Fig. 17 for tine tube lengths.
NOTE: Penetration depth of S-tines may be adjusted by positioning the tine tubes in upper or lower sets of bolt
holes. It is recommended that tube bushings be initially set in upper set of holes which will provide a maximum
penetration depth of 3-1/2”. Mounting tube bushings in the lower set of holes increases penetration depth 1-1/2” to
a maximum of 5”.
Do not attach tube clamps or connecting levers until tines are
positioned and secured.
IMPORTANT: All measurements shown are to centerlines
of lift arms and tines.
Beginning at the centerline of the Superweeder, space tines as
shown in schematics. Tine tubes will have to be slid one way or
another to get the correct spacing. All tines are spaced equally
on center section and all tines are spaced equally on wing sec-
tions.
IMPORTANT: The first S-tines must be correctly positioned
since all successive measurements will be made from them.
The stagger of the first tines must be exact since this repeats over the entire machine.
Keep center tube and wing tubes in a straight line when measuring tine spacing from the center to the wing.
When an S-tine cannot be positioned exactly at the specified spacing because of interference from a lift arm, move
the S-tine left or right the least distance possible to clear obstruction. At this point, it is very important to space the
next tine from the preceding tine to keep the stagger correct.
