Refer to Figure 5
6. Connect your lower tractor 3-point arms to the
planter 3-point hitch. If using quick hitch be sure
planter locks into hitch securely.
This is a semi-mounted implement.
•
Older models have no top link .
•
2007+ models have a flexible top link which may be
used, with care, in certain situations.
•
If the top link is not used, you may optionally use
lift-assist weight transfer to apply some of the cart
weight to the openers during planting.
Refer to Figure 6
If using lift-assist weight-transfer (and not using the
3-point top link), make sure the parallel arms are
configured as follows:
7. Install the lift-assist weight-transfer pins . The pins
are stored in a plate behind the cart parallel arm
pivot weldment. Install them in the large holes at the
bottom of the rod-end lug in the frame-to-cart parallel
arms.
8. Remove the lift-assist shear bolts from the small
holes
below the lift-assist rod-end lug upper pivot
pin. Store the bolts in the plates behind the cart
parallel arm pivot weldments.
If using the 3-point top link, make sure the parallel arms
are configured as follows:
9. Install the lift-assist shear bolts. Spare bolts are
stored in a plate behind the cart parallel arm pivot
weldment. Secure the bolt in the small hole
below
the lift-assist rod-end lug upper pivot pin.
10. Remove the lift-assist weight-transfer pins . These
are located at the bottom of the rod-end lug in the
frame-to-cart parallel arms. The pin is stored in a
plate behind the cart parallel arm pivot weldment.
Refer to Figure 5
11. Connect the flexible top link only for field
operations and maintenance (never for transport).
Adjust the top link with the tractor turnbuckle and the
sliding link
.
For field operations, adjust the top link so that it is
slack with the planter lowered, and taut near the top
of hitch travel with the planter raised. The goal is to
reduce the weight borne by the rear lift assist
cylinders, and reduce any tendency for the tires to
dig on end-of-pass turns and during backing.
12. Raise tractor 3-point just enough to relieve pressure
from the bases of the parking stands.
Excess 3-point weight and steering hazard:
Do not use the top-link and weight-transfer capabilities at the
same time. Planter caster wheels may lift off ground. Tractor
steering wheels may lose effectiveness. An accident is possible,
resulting in serious injury or death, and planter damage.
