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, thereby ensuring an optimised boom function for the end user, even after many years.

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

Super-L3 boom

Super-light, super-stable and super-compact for widths up to 48 m

Super-L3 boom with working widths from 30 to 48 metres
The special AMAZONE profile design of the boom provides maximum stability with a low weight. The inner boom sections of the Super-L3 boom are made of steel. The outer boom sections are manufactured from aluminium to keep the total weight down to a minimum. The advantage of the light-weight outer boom sections is that only a little amount of extra weight has to be guided smoothly over the crop on the outside. Smooth boom guidance at the boom ends is extremely important, especially in the case of large working widths. The profiles of the penultimate boom section of the 48 m wide Super-L3 boom are made of carbon fibre for maximum rigidity with a low weight.

Always the best level of equipment
Super-L3 booms from a width of 39 m are equipped as standard with ContourControl active boom guidance, SwingStop plus boom tip swing compensation and AmaSwitch or AmaSelect individual nozzle control with DUS pro in each case. 

The over-engineered boom sections, with hydraulically pressurised break back joints in the boom ends, ensure an absolutely smooth boom ride under any conditions. If any vibrations caused by cornering or acceleration occur in spite of the massive design, they are directly reduced by SwingStop plus.

Flex-fold for Super-L2 and Super-L3 booms

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:

  • One-sided/simultaneous positive boom angling
  • One-sided/simultaneous negative boom angling (in combination with ContourControl)

”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!"
("profi" - Practice test Amazone UX 5201 Super · 10/2017)


  1. One-sided independent fold (via Flex-fold 1)
  2. Positive angling
  3. Positive angling (via Flex-fold 2)
  4. Negative angling
  5. Negative angling (via Flex-fold 2 in combination with ContourControl)

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 e.g. 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, the active working width is automatically detected and the outer nozzles are deactivated via the AmaSwitch or AmaSelect individual nozzle control. The reduced working width is automatically stored for Section Control.

Automatic boom guidance systems with maximum comfort and even more precision

AutoLift – the comfortable automatic headland system

AutoLift automatic boom lift (standard equipment) lifts the boom to the pre-selected height every time the nozzles are 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. Requirements for this function are just a field boundary saved within the GPS-Switch in the AMAZONE ISOBUS terminal.

DistanceControl or ContourControl? Decide for yourself!

The DistanceControl and ContourControl automatic boom guidance systems offered by AMAZONE provide a suitable solution for every demand. The fully automated DistanceControl boom guidance leaves the control of your sprayer boom in the hands of the machine. 

The innovative ContourControl boom control is AMAZONE’s high-end solution, ideal for customers with difficult terrain conditions. ContourControl provides maximum precision, even at high forward speeds.

DistanceControl with 2 sensors or DistanceControl plus with 4 sensors

As an option on the Super-L boom, AMAZONE offers the DistanceControl fully automated boom guidance system with 2 sensors or DistanceControl plus with 4 sensors for the Pantera self-propelled sprayer. DistanceControl with 4 sensors is recommended if the crop height varies greatly or there are areas with partially lodged corn. The sensors are electrically connected in parallel and so it is always the sensor that is closest to the target surface that is sensing.

  1. Ultra-sound sensors
  2. Angle sensors

Benefits of the DistanceControl boom guidance:

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

ContourControl – Reduces those vertical boom movements

With the active boom guidance system, ContourControl, AMAZONE offers a fully automatic boom guidance system for booms from 21 m working width. This meets the increasing demand for higher precision during application owing to the minimal deviations in the distance from the target surface, even at high forward speeds and large working widths. 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 system is a highly responsive electro-hydraulic system and 4 sensors, or as many as 6 sensors in combination with Flex-fold 2, which enable both automatic positive and negative angling.

The benefits:

  • 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

  1. One-sided positive angling on the right (Flex-fold 2)
  2. Simultaneous positive angling (Flex-fold 2)
  3. Simultaneous negative angling (Flex-fold 2)

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 back and forth 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. To reduce this horizontal tip swing effect, SwingStop measures, via acceleration sensors, the resulting acceleration at the boom ends. 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.

  1. 6 ultrasound sensors for ContourControl
  2. Direction of travel
  3. 2 acceleration sensors for SwingStop
  4. SwingStop ram

The benefits:

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

SwingStop plus

SwingStop plus – independent boom tip swing compensation for both halves of the boom
A new swing compensation system is installed on Super-L3 booms in widths from 39 m which includes the new SwingStop plus boom tip swing compensation. This offers the well-known advantages of SwingStop but differs in that the movements of the two halves of the boom are hydraulically damped independently of each other in the direction of travel. This provides an even better basis for optimum longitudinal distribution of the application.

Reduction in symmetrical and asymmetrical vibrations
SwingStop plus can compensate for symmetrical oscillations which occur through acceleration and braking extremely effectively. The new design of the swing compensation system now permits the individual control of either boom half. In SwingStop plus, each boom section is equipped with a hydraulic cylinder which actively counteracts any oscillations which occur in that boom half. This means that even asymmetrical boom oscillations which occur after negotiating bends are effectively reduced.

SwingStop plus (1) SwingStop plus_1
Symmetrical oscillation mainly during field work

SwingStop plus (2) SwingStop plus_2
Asymmetrical oscillation mainly in and after bends
