Load Shift and Field Tracking Risks:
Adjust 3-point hitch arms and sway blocks to minimize any
side-to-side sway to assure proper tracking in the field and
safe road travel.
Refer to Figure 4
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.
• The flexible top link , 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.
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.
Refer to Figure 5
If using lift-assist weight-transfer (and not using the 3-
point top link), make sure the parallel arms are config-
ured 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 par-
allel 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.
