Preparation and Setup
This section helps you prepare your tractor and fertilizer
applicator for use, and covers tasks that need to be done
seasonally, or when the tractor/fertilizer applicator
configuration changes.
Before using the applicator in the field, you must hitch it
to a suitable tractor, inspect systems, level the applicator,
and then hitch a suitable nurse tank to the applicator.
Before using the fertilizer applicator for the first time, and
periodically thereafter, certain adjustments and
calibrations may be required.
Anhydrous Ammonia Exposure Hazard:
Do not modify the NH
3
system of this applicator.
Designing NH
3
systems, selecting and installing components
is serious engineering. Testing a custom system could be
extremely hazardous (and field PPE
a
is inadequate for such
testing). Malfunction of a custom system could result in a
major release of NH
3
gas or liquid.
Initial Setup
See manual 407-313Q for pre-delivery items (normally
completed by dealer).
Other first-time/infrequent setup tasks include:
• 2-Point: set lift assist valve (page 155).
• Install meter console in tractor (page 155).
• Install any Options not factory- or dealer-installed.
Post-Delivery/Seasonal Setup
On initial delivery, use with a new tractor, and seasonally,
check and as necessary, complete these items before
continuing to the routine setup items:
• Bleed hydraulic system (page 120).
• De-grease exposed cylinder rods if so protected at last
storage.
• Verify that all time-dated components are within their
service lives.
a. PPE: Personal Protective Equipment
Anhydrous Ammonia Release Hazard:
Use only the Great Plains rear hitch for a trailing nurse tank
cart. A custom hitch and/or mount, including any safety chain
anchors, could fail entirely, resulting in a tank cart upset.
Consequences could include a catastrophic release of NH
3
.
At the very least expect a breakaway event and cart damage.
