Hitching Nurse Tank
Hitch a nurse tank to the implement only at the field, and
not prior to transport.
Mechanical Cart Hitching
1. Spot the implement to avoid reverse moves after cart
hitching.
Refer to Figure 30
2.
Bring the implement rear hitch tongue and nurse
tank cart tongue into close proximity (a few inches).
3. Push down on the red tongue release handle .
This frees the implement rear hitch tongue to
extend 7 inches (17.8 cm) to the rear, and 9 inches
(23 cm) to either side, to assist with cart tongue
alignment.
4. Align the cart clevis hitch with the implement pull
bar. Insert and secure the 1 inch (2.6 cm) hitch pin.
5. Securely attach the cart’s safety chain(s) to the
hitch chain anchor(s) .
6. Optionally re-seat the implement rear hitch tongue,
at this time, by using the tractor to move the
implement backward several inches, until the latch
on the hitch re-engages.
Making Nurse Tank Connections
1. Close shut off valves on all hoses of both tank
and implement
.
2. Route tank supply hose to implement inlet .
Allow ample slack for tight field turns and uneven
ground. Do not leave so much slack that the hose
can reach the ground.
3. Remove plug from implement inlet, and any cap on
tank supply hose.
4. Inspect and clean connector fittings.
5. Mate connectors of tank and implement supply
hoses. Fold cam levers forward to lock. Leave valves
closed.
6. If the tank has additional hoses, secure them at the
tank.
