Preparation and Setup
20
Hitching with Hydraulic Tongue (Option)
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 “
” on page 17. Allow slack for hitch
movements. Close the tongue cylinder bypass valve.
3. Make electrical connections for at least the
implement name control circuit (necessary to control
implement name hydraulic systems). See page 19.
4. Check that hitch local bypass valve
is closed.
5. Set the cab Clutch Folding Module 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.
7. Connect safety chain to a suitable anchor point on
the tractor.
8. Extend the Hitch/Lift circuit to raise the hydraulic
tongue just enough to relieve pressure from the
parking stand.
9. Remove and store main tongue parking stand. See
Local Float on Hydraulic Tongue
Equipment Damage Risk:
The hydraulic tongue must be in Float during implement name
moves.
If it is necessary to move the implement name without
first connecting 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.
Raising/Lowering Tongue
In addition to hitching, tongue raising and lowering is
required during fold and unfold to engage and disengage
the wing locks.
With the standard 3-point hitch, the product tongue is
raised and lowered by raising and lowering the 3-point.
With the optional hydraulic tongue, the product tongue is
raised by extending the hitch cylinder, and lowered by
retracting the hitch cylinder.
