3-Point Hitch
Refer to Figure 5
10. Connect your tractor 3-point to the planter 3-point
hitch. If using quick hitch be sure planter locks into
hitch securely.
11. Raise tractor 3-point just enough to relieve pressure
off of the parking stand.
Load Sway Risk:
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.
12. Connect hydraulic hoses to tractor remotes. See
“Hydraulic Hose Hookup” on page 13
Hitching with Hydraulic Tongue (Option)
Refer to Figure 6
1.
Move the tractor to near hitching position.
2. Connect the hydraulic hoses for the tongue circuit.
This needs to be done before hitching in order to
raise and lower the tongue. See “Hydraulic Hose
Hookup” on page 13. Allow slack for hitch move-
ments. Close the tongue cylinder bypass valve.
3. Make electrical connections for at least the planter
control circuit (necessary to control planter hydraulic
systems). See page 16.
4. Check that hitch local bypass valve is closed.
Refer to Figure 7
5.
Set the cab CFM Lift/Hitch switch to Hitch.
6. Retract the Hitch/Lift circuit to set the tongue height
to clear the draw-bar. Back the tractor into alignment
and pin the draw-bar.
Local Float on Hydraulic Tongue
Refer to Figure 6
The hydraulic tongue must be in Float during planter
moves.
If it is necessary to move the planter without first con-
necting it to a tractor that has a float-capable circuit for
the hydraulic tongue, open the bypass valve
on the
tongue cylinder. This provides local floating capability at
the tongue.
