Booms in an aircraft wing design

Both superbly robust and superbly light

Thanks to the special profile design AMAZONE booms are at the same time superbly light and superbly strong. The boom working widths from 15 to 36 metres allow the optimised matching of the sprayer to the structure of the farm. The exceptionally high-quality ensures a long operational life even over very high acreages.

The compact transport dimensions with transport widths of 2.40 m to 2.85 m also contribute to the safe transport on the road.

Everything shipshape: The boom is located safely without movement in its transport position. The parallelogram suspension dampens shock loads in the field as well as in the transport position. This is pure comfort and, above all, ensures the long service life of the boom.

  1. fixed rest
  2. sprung rest

No spray agent from the booms drips on to the tractor. The booms also do not hit the tractor cab.

Focusing on the essentials: the road in front of you
You can concentrate entirely on driving. The visibility in road transport is exemplary. Where the tractor can get through then the trailed sprayer can also pass. No protruding parts, no boom damage.

Maintenance-free and with a long service life

The decades of experience in boom design pay off: The conical hinge pin is the intelligent centre of a well thought-out boom philosophy! The boom pivots self-adjust against any play on the conical hinge pins and that ensures, for the end user, an optimised boom function even after many years.

The standard use of stainless steel, the automotive-industry standard, cathodic dip painting process and the targeted use of plastics and aluminium are the perfect guarantee of a long service life.

The first-class Super-L boom – smooth-travelling and precise application comes as standard

Thanks to the central pendulum suspension, the Super-L booms are guided with ease, even in their standard execution.

The benefits:

  • a particularly long central pendulum system means easy parallel guidance of very wide booms
  • combined spring and damping elements for shock-dampening the suspension against vertical forces
  • integrated damping system consisting of braking plates and buffer blocks to damp down the horizontal yaw movement

Super-L3 boom

In 36 m working width

The Super-L3 boom supplements the 36 m working width Super-L2. The outer and middle boom sections each have a length of 6 m, so that the Super-L3 boom is made up of only 3 sections each side. This makes it possible to use the 36 m Super-L3 boom also at a reduced working width of either 24 m or 12 m. The end boom sections come fully constructed in aluminium with additional bracing bars. This ensures very high robustness yet with a very low weight.

Pre-select folding

One-sided, independent folding via tractor spool valves is possible with the AmaSpray+ or an ISOBUS terminal.

The high level of flexibility offered by the pre-select folding function enables all boom sections to be folded individually. Both the left and right-hand sides can be folded in separately and independently of each other, in order to adapt to any circumstances in the fields.

Profi-fold 1

All the hydraulic functions can be carried out safely and simply via the ISOBUS terminal in the tractor cab. The multi-function joystick makes handling particularly comfortable.

The following functions are possible:
Height adjustment, folding in and out, independent, one side folding at reduced speeds (max. 6 km/h), boom width reduction, and tilt adjustment.

AMAZONE offers two electro-hydraulically boom folding options, Flex-fold 1 and Flex-fold 2. Each boom folding joint is equipped with an electro-hydraulic valve block that is directly controlled by the machine software. This enables faster folding procedures. As soon as the first boom section is folded in or out by approximately 70%, the next section automatically starts to fold in or out.

Flex-fold 1
In addition to the benefits already outlined, Flex-fold 1 provides the following functions: 

  • Height adjustment
  • Folding in and out
  • One-sided independent folding at reduced speeds (max. 6 km/h)
  • Boom width reduction
  • Tilt adjustment

Flex-fold 2
In addition to the advantages mentioned previously, Flex-fold 2 offers the following functions:

  • Independent / both-sided positive boom angling
  • Negative boom angling of individual / both sides

”To speed up the folding procedure, AMAZONE has replaced the simple sequence control by a sensor controlled process. With this we clocked a quick 19 seconds for folding out and 27 seconds for folding in – great!"

Individual user profiles with reduced working widths

Via the user profiles in the machine software, individual profiles that recognise a reduced working width can be stored. If, for instance, it is intended to fold out a 36/30/24 m boom to just 30 m, this can be carried out quickly and simply via a profile change. After folding out just the relevant sections, the active working width is automatically detected and the outer nozzles are automatically deactivated via AmaSwitch or AmaSelect. For section control, the working width is automatically stored.

Boom guidance systems

DistanceControl or ContourControl? Decide for yourself!

The AutoLift automatic headland system and the DistanceControl and ContourControl automatic boom guidance systems offered by AMAZONE provide the right solution for every need. Just utilising the standard AutoLift already provides convenient assistance. The fully automated DistanceControl boom guidance leaves the boom control almost completely in the hands of the machine.

The innovative ContourControl boom control is AMAZONE’s high-end solution, ideal for customers with difficult terrain conditions. In addition to fully automated height guidance, ContourControl also offers active vibration damping for the boom. ContourControl satisfies the demand for higher accuracy, even at faster forward speeds.

Automatic boom lowering via GPS-Switch

The GPS-Switch function in the operator terminal can be used to start lowering the boom before it reaches the untreated area. This means that the boom is already at the correct working height when the nozzles come on. Requirements for this function are just a field boundary saved within the GPS-Switch in the AMAZONE ISOBUS terminal.

AutoLift – the comfortable automatic headland system

The AutoLift automatic boom lift (standard equipment) lifts the boom to the pre-selected height every time the machine is switched off. It lowers back down again to the target height when the sprayer sections are switched on. This reduces the risk of damage to the boom while turning on the headland.

  • Automatic boom lowering via GPS-Switch
    The GPS-Switch function in the operator terminal can be used to start lowering the boom before it reaches the untreated area. This means that the boom is already at the correct working height when the nozzles come on. The only requirement for this is a field boundary saved in the GPS-Switch and an AMAZONE ISOBUS terminal.

DistanceControl with 2 sensors or DistanceControl plus with 4 sensors

AMAZONE offers for Super-L booms, either DistanceControl fully automated boom control with 2 sensors or Distance- Control plus with 4 sensors. If the crop height varies greatly or there are areas with partially lodged corn, the boom could dip into the crop when equipped with 2 sensors. In this case, equipping the boom with 4 sensors will prevent this. The sensors are electrically connected in parallel and so it is always the sensor that is closest to the target surface that is actuated.

The driver is able to concentrate on correctly applying the plant protection agent, whilst the computer optimises the boom guidance!

Benefits of the DistanceControl boom guidance:

  • Fully automatic boom guidance including height guidance, tilt adjustment and boom lifting on the headland
  • Automated bilateral boom angling (in combination with Flex-fold 2)

  1. Ultra-sound sensors
  2. Angle sensors

ContourControl – reduces those vertical boom movements: The AMAZONE ContourControl active boom guidance is a ground-breaking fully automatic boom guidance system for booms from 21 m working width. This meets the demand for higher precision during application owing to the lower target surface distances even at high forward speeds. ContourControl can be used with Super-L booms in conjunction with either Flex-fold 1 or Flex-fold 2.

The basis of the new boom guidance is the highly-responsive, electro-hydraulic system with either 4 sensors or in, combination with the Flex-fold 2, 2 additional sensors which allow control of any negative geometry.

The benefits of ContourControl:

  • Optimum lateral distribution
  • Precise, super-fast automatic height guidance
  • Target surface distance below 50 cm – less drift
  • Very quick folding processes
  • Higher accuracy at faster working speeds
  • Elegant boom control for those wider working widths

SwingStop – for reducing the horizontal boom movement

In order to tailor the horizontal boom ride to the growing demands, e.g. wider working widths and higher forward speeds, AMAZONE offers the SwingStop active boom tip movement prevention as an option for the ContourControl boom guidance system. By external influences, such as ground undulations, driving round bends, acceleration and deceleration and increasing operating speeds the boom is put under extraordinary strain in the horizontal direction. This may result in the boom ends swinging round and thus negatively affecting the lateral distribution at the outer ends of the booms.

As horizontal movement occurs more at the boom ends, this effect is increased enormously by wider boom widths. SwingStop measures the acceleration in the boom outriggers via acceleration sensors, in order to reduce these horizontal oscillations. The two actively-operating hydraulic rams in the boom suspension compensate live for these swing movements and in this way provide a very smooth horizontal boom ride.

The benefits of SwingStop:

  • Optimum longitudinal distribution
  • Reduction in the horizontal boom movement for an extremely steady boom ride
  • A system that operates very quickly, elegantly and precisely, even at very high working speeds
  • Highest performance and outstanding precision

"A total of six ultrasound sensors take care of the height guidance of the parallelogram frame, the adjustment of the slope compensation and the control of the boom angling (positive and negative). It is fantastic in hilly terrain, particularly when it comes to being able to spray more quickly with a shorter distance above the target surface."
("profi" - "Practice test Amazone UX 4201 Super" · 02/2020)

"And now when it comes to the keyword "fast", then "SwingStop" also comes into play: This is an active, hydraulic control system with acceleration sensors in the ends of the boom which counteracts horizontal swinging - and does so before any movement visible to the eye occurs."

LED individual nozzle lighting

Professional work lighting is today the basis of a flexible, output-increasing solution to operating in twilight and at night. LED individual nozzle lighting picks out each individual spray fan. An absolutely immediate assessment of their operation down to the very last nozzle on the boom can be made.

LED work lights

Boom lighting is provided by two LED work lights mounted in the centre of the boom and, from here, due to their wide-reaching illumination; prove to be a particularly effective execution.

Two further LED work lights to give additional background lighting can be mounted up on the platform.
