Boom
Boom configurations
The TERRA FORCE boom is pendulum suspended, fully hydraulically operated with all functions controlled via the Direct
Hydraulic System (D.H.).
The TERRA FORCE boom is suspended from a parallelogram with nitrogen dampers and is available in 88’, 90’, 100’, 120’
and132’ (26.8, 27.4, 30.5, 36.6, 40.2 m) working widths. The 88’ - 100’ booms have bi-fold wings, while the 120’ - 132’ booms
have tri-fold wings.
Boom features:
•Hydraulic pendulum lock.
•Outer most sections incorporate spring-loaded breakaway.
•Tilt control with individual suspension (DynamicCenter only).
•Partial folding of outer sections. This enables alternative boom widths.

DynamicCenter
The TERRA FORCE boom features a DynamicCenter system that can adapt the boom suspension for different conditions.
DynamicCenter provides hydraulic remote control of the suspension characteristics. The settings are selected on the go and
will change the boom behavior from being free to fully stabilized.
The system is adjustable in 5 steps between two absolute points of adjustment:
AutoTerrain (optional equipment)
AutoTerrain is an electro-hydraulic automatic boom management system which adapts the boom suspension for different
field conditions on both boom movements and twisting forces on the boom. This allows the AutoTerrain to be proactive
and react on the cause more than on the symptom.
ATTENTION! Please refer to the AutoTerrain manual for detailed information about operation, calibration and
maintenance of the AutoTerrain system.
DynamicCenter step Pendulum state Terrain Behavior
1 Free pendulum Flat field 10% sprayer following. Boom is stable in horizontal position.
2-4 Partly stabilized pendulum Field with slopes Boom follows the sprayer’s angle to some extent.
5 Fully stabilized pendulum Hilly field 80% sprayer following. Boom follows the sprayer’s angle in hilly terrain.

Hydraulic systems
General info
Ensure that the quick couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check the vehicle’s hydraulic oil level and top off, if
necessary.
€DANGER! Test of the hydraulic system should be done very cautiously. There may be air trapped in the system which
can cause violent movements of the boom.
€DANGER! Hydraulic leaks: Never use your fingers to locate a leakage in any part of the hydraulic system. Due to high
pressure, hydraulic oil may penetrate the skin.
Requirements - tractor (TERRA FORCE model)
The hydraulic system requires:
•One double-acting outlet for the electro-hydraulic operation of the boom functions. The hydraulic hoses are marked
with arrows and colored tie straps to indicate direction of oil flow. Red tie strap = pressure. Green tie strap = Return to
tank. The hoses must be hooked up to the correct outlet for the hydraulics to function properly (pressure hose to
pressure outlet, return hose to tank outlet).
•Oil flow between 4 - 10 gal/min. (15 - 38 l/min) and a min. pressure of 2610 psi (180 bar).
•Maximum permissible oil pressure is 3050 psi (210 bar).
•Return flow of the connected tractor must be maximum 215 psi (15 bar).
•For Load Sensing systems an oil flow of approximately 0.8 gal/min (3 l/min) at 360 psi (25 bar) supplied by the sprayer
hydraulics.

Boom
Yaw damper gauge
The damper takes energy out of the boom to stabilize the yaw
movements. The yaw damper is charged with nitrogen and equipped
with a pressure gauge that must be checked before spraying. Unfold the
boom and confirm that the pressure in the yaw damper gauge is in the
green range: 290 - 435 psi (20 - 30 bar).
If the pressure gauge reads outside the green range with boom
unfolded and stationary, do not use sprayer! If the nitrogen pressure
charge is lost, the system will not function correctly and you must stop
spraying immediately or severe damage to the boom may occur. Any
damage caused by spraying with a faulty yaw damper will not be
covered under warranty.
±WARNING! Verification and refill/adjustment of the nitrogen pressure in the damper must be carried out by your
HARDI® dealer’s workshop.
±WARNING! Yaw dampening circuit pressure gauge must be in green range with boom unfolded or severe damage to
boom may occur. Check daily.

5.1
Boom
Safety info
The boom must not be folded/unfolded while driving! Never use the folding/unfolding functions before the sprayer has
been stopped! Failure to do so will damage the boom.
€DANGER! Before unfolding the boom it is important to connect trailed sprayers to the tractor to prevent overturning
the sprayer.
€DANGER! When folding or unfolding the boom, make sure that no persons or objects are within the operating area
of the boom.
€DANGER! Always follow the guidelines listed below when driving in areas with overhead power lines:
Never use the folding/unfolding functions in areas with overhead power
lines.
Unintended boom movements may cause contact with overhead
power lines.
ATTENTION! Only unfold and fold the boom on level ground.

Maneuvering of the boom - TERRA FORCE
±
WARNING! The pendulum lock automatically turns ON when pressing one of the folding buttons. Boom folding is not
possible if the pendulum is unlocked. A manual override of the pendulum lock is possible by activating switches 2 or 3
on the SetBox or switch 4 on the self-propelled instrument panel.
±WARNING! Only operate the folding functions when the sprayer is stationary! Failure to do so may damage the boom.
The pendulum lock automatically opens at speeds exceeding 0.9 mph (1.5 km/h)!
ATTENTION! If a folding sequence is not completed, a warning message on the Hardi display will ask you to complete
this sequence before starting next sequence.
ATTENTION! Only buttons relevant for boom functions are mentioned here.
To unfold the boom using the SetBox & Grip controls (Trailed models)
1. Press the boom lift button (H) to lift the boom clear of the transport
brackets.
2. Press and hold (A) and (C) to tilt boom wings up.
