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:
Refer to Figure 56
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. Figure 56
