Nurse Tank Cart Components
For use with a Nutri-Pro
®
applicator, the nurse tank must
be a full-trailering pull-type with two or more axle running
gear. The Nutri-Pro
®
is not designed to pull a semi-
mounted tank.
Note: Callout numbers A51 through A87 identify the
same nurse tank components throughout this
manual and the applicator Operator manual.
Cart Hitch
Refer to Figure 2
A51 A Nutri-Pro
®
applicator requires a nurse tank with a
clevis hitch having a locking 1 inch (2.5 cm) pin. See
the applicator Operator manual for cart hitching and
page 31 for unhitching.
A52 At least one safety chain is required. In some
regions, regulations may already require two safety
chains. Each chain, clasp, and weld must be rated
for the gross weight of the loaded cart.
A53 The tongue may have supports or caddies for hose
management (the depicted cart has the Acme
parking plug on top). Make sure you understand the
purpose of any tongue features.
When the nurse tank hose is attached, check that
the forward point at which it is secured to the tongue
or cart frame is at least 3 feet (92 cm) from the
implement break-away, with enough slack to elevate
the hose at least 13 inches (33 cm) above the
implement breakaway.
Note: Nutri-Pro
®
implements do not provide a lighting
harness at the rear hitch, as field operations do not
require nurse tank lights. If the nurse tank has
lights, make sure there is provision to secure that
harness during field operations.
Note: A Nutri-Pro
®
implement does not provide pass-
through connections for air, hydraulic or electric
brakes, as field operations do not require brakes.
If the nurse tank has brakes (rare), make sure they
can be set to off (freewheeling), and there is
provision to secure the unconnected brake lines
during field operations.
A54 Nurse tank cart tongues typically have unlimited
vertical movement. If the tongue pivots have stops,
make sure the clevis can be elevated to at least
48 inches (122 cm) above ground (for implement lift
in field turns).
