Super-light, super-stable and super-compact at the same time

Thanks to the special profile design, AMAZONE booms are, simultaneously, superbly light and superbly strong. Boom widths from 21 to 48 m allow optimum adaptation of the sprayer to the field size of the farm. The exceptionally high-quality ensures a long operational life even across very high acreages. 

The compact transport dimensions with transport widths from 2.40 m also contribute to 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.

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.

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.

A high-grade, multi-layer paint finish ensures top quality that lasts.

The 4-fold damped Super-L booms – smooth-travelling and precise application as standard

Boom guidance of the Super-L boom is optimised by the central pendulum suspension. In addition, the combined spring and damping elements provide an enormous reduction in any potential vertical movement. Also the horizontal pivoting movements are kept at a minimum by the integrated damping system so that, for all AMAZONE booms, optimum work results are achieved.

The benefits: 

• a particularly long central pendulum system means 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-L2 boom in boom widths from 21 to 36 metres

Superbly narrow transport width of just 2.40 m on all three-fold Super-L2 booms in boom widths of 21, 24, 27 and 28 m. Amazing transport width of only 2.60 m on all four-fold Super-L2 booms in boom widths of 27, 28, 30, 32, 33 and 36 m (UX 6201: 2.80m).

Super-L3 boom with working widths from 30 to 48 metres
The special AMAZONE profile design of the boom provides maximum stability with low own 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.

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 actuated boom fold 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 extra functions:  

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

Benefits of Flex-fold:  

• Shorter turn-round times through quicker folding 
• Easy working width Regulation

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

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.

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.

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.

1. Working height
2. Headland height

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.  

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

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)

In order to tailor the horizontal boom ride to the growing demands, e.g. wider widths and higher forward speeds, AMAZONE offers 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 under extraordinary strain in the horizontal plane. 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.

Since horizontal movement occurs more at the boom ends, this effect is amplified by large 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.

The benefits of SwingStop: 

• Optimum longitudinal distribution 
• Reduction of the horizontal boom movement for a very smooth boom ride 
• A system which operates very quickly and precisely, even at 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 and with a shorter distance above the target surface.”

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.

SwingStop plus – independent oscillation damping for both halves of the boom

A new swing compensation system is used with Super-L3 booms in boom 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.

Reducing symmetrical and asymmetrical oscillations

SwingStop plus can compensate extremely effectively against symmetrical oscillations which occur through acceleration and braking. 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.
