Boom
Boom and terminology
The TERRA FORCE boom is a pendulum suspended, fully hydraulically operated Z-version with all functions controlled via
the Direct Hydraulic System (D.H.).
The TERRA FORCE boom is suspended in a parallelogram with nitrogen dampers and is available in 36, 39, 40 and 42 m
working width. All booms are 3-folded.
Boom features:
•Hydraulic pendulum lock.
•Outer sections incorporate spring-loaded breakaway.
•Tilt control with individual suspension (option).
•Individual folding of outer sections (option). This enables alternative boom widths.
For 3-folded booms the terminology is as follows:
A. Breakaway section
B. Short outer section
C. Intermediate section
E. Inner section
F. Centre section
÷NOTE! When controlling the boom at the SetBox, the folding sections are:
X. Breakaway section
Y. Intermediate section
Z. Inner section
DynamicCentre
The TERRA FORCE boom features a DynamicCentre system that can adapt the boom suspension for different conditions.
DynamicCentre has hydraulic remote control of the suspension characteristics. The setting is done on the go from the cabin.
It will change the boom from being 10% sprayer following (pendulum-like) to be 80% sprayer following (trapeze-like).
The system is adjustable in 5 steps between the two absolute points of adjustment:
AutoTerrain (optional equipment)
AutoTerrain is an electro-hydraulic automatic boom management system which adapts 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.
μATTENTION! Please refer to specific book for information about AutoTerrain.
DynamicCentre step Pendulum state Terrain Behaviour
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 sprayers heeling angle to some extent.
5 Stabilized pendulum Hilly field 80% sprayer following. Boom follows the sprayer’s heeling angle in hilly terrain.

4 - Sprayer setup
Hydraulic systems
General info
Ensure that the snap couplers are clean before connection!
After having operated the boom and the system has been filled with oil, check the tractor’s hydraulic oil level and top up, 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.
μATTENTION! The hydraulic hoses are marked with arrows to indicate the direction of oil flow.
•Oil flow between 50 and 130 l/min and a min. pressure of 190 bar.
•Maximum permissible oil pressure is 210 bar.
•Return flow of the connected tractor must be maximum 15 bar.
•For Load Sensing systems an oil flow of approximately 3 l/min at 25 bar supplied by the sprayer hydraulics.

Boom
Yaw damper adjustment
The damper takes energy out of the boom to stabilize the yaw
movements. This can be used to compensate for different driving
conditions.
Adjust the damper until boom movements are restricted, but without
stiffening the boom.
Default setting
If out of adjustment, the starting point is set as follows:
1. Turn adjuster screw all way in (clockwise/negative direction).
2. Then turn the screw out 2.5 turn (counterclockwise/positive
direction).
Steering behaviour Dampening Adjuster screw direction
High speed in uneven terrain Increase Clockwise (negative)
Low speed in flat terrain Decrease Counterclockwise (positive)

5 - Operation
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 the sprayer to the tractor to prevent overbalancing
of 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.
μATTENTION! A label (ref. no. 978448) follows the sprayer. This label
must be placed in the cabin visible from the operator’s seat.
μATTENTION! Only unfold and fold the boom on level ground.

Manoeuvring 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.
±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 1.5 km/h!
μATTENTION! If a folding sequence is not completed, a warning message will ask you to complete this sequence before
starting next sequence.
μATTENTION! Only buttons relevant for boom functions are mentioned here. Refer to “Boom” on page 11 for
descriptions of other buttons.
To unfold the boom
±WARNING! The pendulum lock automatically opens when you begin to drive. Drive slowly until the pendulum is
completely unlocked.
1. Push the lift up button (H) to lift the boom clear of the transport
brackets. The symbol appears in display until pendulum is
locked. This takes approximately 10 seconds.
2. Push the button (5) to unfold the inner sections completely
(approximately 5 sec. or a warning will appear). Check that the
pendulum locked symbol is visible in the display.
3. Push the button (7) to unfold the intermediate sections.
4. Push the button (9) to unfold the outer sections (sequential folding
only).
5. If no tilt wires fitted, press (B) and (D) to tilt boom wings down to
working position.
6. Push the lift down button (I) to lower the boom to the correct working height.
7. If not unlocked, then press (2) and symbol appears in display until pendulum is unlocked. This takes approximately
10 seconds.
To fold the b oom
1. Push slant buttons (E) or (F) to set neutral slant angle (no slant).
2. If no tilt wires fitted, press (A) and (C) to tilt boom wings up.
3. Push lift up button (H) to raise the boom to the highest possible
position.
4. Push the button (8) to fold the outer sections (sequential folding
only). The symbol appears in display until pendulum is locked.
This takes approximately 10 seconds.
5. Push the button (6) to fold the intermediate sections. Check that
the pendulum lock symbol is visible in the display.
6. Push the button (4) to fold the inner sections.
7. Push the lift down button (I) to lower the boom until it rests in the
transport brackets.
÷NOTE! On sequential folded booms intermediate and outer
wings are folded/unfolded simultaneously. As consequence the
unfold buttons (7) and (9) and the fold buttons (6) and (8) have the same function.
