field precautions. Although ammonia
release is not expected for mechanical hitching, the tank could
be venting small amounts, or large amounts if mis-configured,
or if a component fails. On a re-hitch, the applicator may also
be venting residual material. Unprotected exposure could
cause serious lung or eye irritation.
Hitch a nurse tank to the applicator only at the field, and
not prior to transport.
If taking delivery of a tank at the field, complete an
inspection (see “
Using Anhydrous Ammonia Safely
manual (407-551M) before accepting the tank.

: Mechanical Cart Hitching
1. Spot the applicator. Three objectives are:
2. Bring the applicator 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 applicator 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 applicator pull bar.
Insert and secure the 1 inch hitch pin.
5. Securely attach the cart’s safety chains to the hitch
chain anchors .
6. Optionally re-seat the applicator rear hitch tongue, at
this time, by using the tractor to move the applicator
backward several inches, until the latch on the hitch
re-engages.
All tank carts:
•
Spot to avoid reverse moves after cart hitching.
•
Face the tractor and applicator basically up
wind, but with a cross-wind component such
that:
•
the hose connection(s) and valve operations will
be made down-wind of where you stand for
those operations.
