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:
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.
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.
ATTENTION! Please refer to specific book for information about AutoTerrain.

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.
ATTENTION! The hydraulic hoses are marked with arrows to indicate the direction of oil flow.
μ
• 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.
Steering behaviour Dampening Adjuster screw direction
High speed in uneven terrain Increase Clockwise (negative)
Low speed in flat terrain Decrease Counterclockwise (positive)
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).

boom must be unfolded and tilted completely down to horizontal
position. If necessary, adjust the wing as follows:
1. Support the boom on jack stands to relieve the load from the hydraulic cylinder.
2. Loosen grub screw (A).
3. With a 27-wrench on key profile (B) at end of the ram, adjust the
cylinder ram to get the desired wing level.
4. Tighten the grub screw (A) again.
5. Repeat steps for the other side.
Wear bushing renewal on boom lift
Inspect and replace the wear bushes before they are worn through.
1. Connect the trailer to a tractor and unfold the booms to working position.
2. Lift the boom centre frame with a lifting device and support it until the load is taken off the parallelogram arms.
3. Remove the screws (A), pull out the pins (B) at one of the upper parallelogram arms and replace the wear bushes.
4. Refit the arm.
5. Repeat this on the other upper arm.
6. The lower arms must be disconnected simultaneously.
7. Grease all grease nipples.
8. Remove the lifting gear again.

Operational problems
General info
Operational incidents are frequently due to the same reasons:
1. A suction leakage reduces the pump pressure and may interrupt suction completely.
2. A clogged suction filter may damage suction or interrupt and prevent the pump from running normally.
3. A clogged pressure filter increases pressure in the fluid system in front of the pressure filter. This may blow the safety
valve.
4. Clogged In-line or nozzle filters increase pressure in the pressure gauge but decrease pressure at the nozzles.
5. Impurities sucked by the pump may prevent the valves from closing correctly, thus reducing the pump flow.
6. A bad reassembly of the pump elements, especially the diaphragm covers, causes air intakes or leaks and reduces the
pump flow.
7. Rusted or dirty hydraulic components cause bad connections and early wears.
8. A badly charged or faulty battery causes failures and misbehaviour in the electrical system.
Therefore ALWAYS check
1. Suction and pressure filters, as well as nozzles, are clean.
2. Hoses for leaks and cracks, paying particular attention to suction hoses.
3. Gaskets and O-rings are present and in good condition.
4. Pressure gauge is in good working order. Dosage accuracy depends on it.
5. Operating unit functions properly. Use clean water to check.
6. Hydraulic components are clean.
7. The good condition of the tractor battery and its connectors.
