3.3.8 INSTALL ADJUSTABLE HITCHES
Note: Tube height shall be set with the object of having the cart
arms as close to parallel to the ground when in operating posi-
tion in the field. Toolbar hitch field operating height is needed to
determine proper tube height. Tube mounting gusset (C) must
be used (either above or below arm) with both u-bolts. This al-
lows for greater height adjustability.
1.
Install ball hitch or knuckle hitch on each arm as illustrated
using two ¾-10 x 4 wide x 5½ inch long U-bolts (A) with lock
washers and nuts (B). Tighten nuts until all four nuts are in
contact with plate. Make sure the hitch location reflects the
desired height of the arm.
2.
Starting with top u-bolt (A), alternate tightening each nut in
25 lb/ft (34 Nm) increments until both nuts are tightened to
150 lb/ft (204 Nm) of torque. Then tighten each nut to 160
lb/ft (217 Nm) of torque. Avoid over tightening either side.
Repeat tightening procedure for bottom u-bolt.
3.
Place the tube mounting gusset (C) as shown, either above the arm (for a lower arm height - Fig. A), or below the arm
(for a higher arm height - Fig. B). Secure with u-bolts (D), with lock washers and nuts (E). Tighten until all four nuts are
in contact with the gusset plates.
4.
Repeat step 2 to fully tighten nuts onto u-bolts.
3.3.9 INSTALL DRIFT ASSIST HITCH (OPTIONAL)
1.
Install Drift Assist mechanism with the transport pin (D) in
the transport position.
2.
Install Drift Assist hitch on arm as illustrated using three 3/4-
10 x 4 wide x 5 1/2 inch long u-bolts with lock washers and
nuts. Tighten nuts until all six nuts are in contact with plate.
Set height of knuckle to align with the knuckle height on the
left arm.
3.
Starting with middle U-bolt (A), alternate tightening nut (B)
and nut (C) in 25 lb/ft (34 Nm) increments until each nut is
tightened to 150 lb/ft (204 Nm) of torque. Then tighten each
nut to 160 lb/ft (217 Nm) of torque. Avoid over tightening
either side.
4.
Repeat tightening procedure for top and bottom U-bolts.
