Note: Set hitch so tongue of drill is parallel to
ground when drill is in planting position. Use
tongue jack to level tongue, then find closest set-
ting of hitch to match your tractor drawbar height.
3. Attach safety chain on tongue hitch to tractor
and lock hook securely on chain. Adjust chain
length to remove all slack except what is nec-
essary to permit turning of the drill and tractor.
4. The tongue jack makes it possible to raise or
lower the hitch for tractor unhooking and re-
connecting. Always return jack to its horizon-
tal position on top of the tongue at the pull bar
slide stop.
Tractor Hydraulic Hookup
For ease of operation, your tractor should be
equipped with six remote hydraulic outlets (three
pairs). This will allow you to connect one pair to
the drill lift circuit, one pair to your drill fold circuit
and one pair remaining for connection of optional
markers. If your tractor has only four remote out-
lets (two pairs) and a marker circuit is required, a
marker sequences valve with double selector is
available through your Great Plains dealer.
Hydraulic Hose Hookup
Refer to Figure 5
Great Plains hydraulic hoses are color coded to
help you hookup hoses to your tractor outlets.
Hoses that go to the same remote valve are
marked with the same color.
To distinguish hoses on the same hydraulic circuit,
refer to plastic hose label. Hose under extended-
cylinder symbol feeds cylinder base ends. Hose
under retracted-cylinder symbol feeds cylinder
rod ends.
