NAVIGATOR - The Obvious Choice

NAVIGATOR is synonymous with high quality and design which supports functionality. Properties which secure the value for money and ease of use. In the HARDI trailer family, NAVIGATOR offers features from mid-size to full specifi cation solutions.


The large range of high quality features makes the NAVIGATOR the obvious choice. Demands for simple and reliable solutions, serviceability and high capacity are universal world-wide. The product represents HARDI’s experience as sprayer specialist. The proven success for NAVIGATOR sprayers since the introduction has shown the value of this position.



IntelliTrack is a high-end steering drawbar concept combining the advantages of an excellently designed chassis with the use of advanced electronics. The tracking concept is easy to connect and operate, ensuring safe tracking even in difficult field conditions. IntelliTrack has an integrated safety feature which prevents the cylinders from steering the drawbar when the driving speed is too high for the given track width.


The DynamicFluid4 system will calculate the consequences of the increased RPM and make the regulation instantly. The DynamicFluid4 property of pro-acting is based on 4 sensors in the fl uid system measuring RPM, position of regulation valves, flow and pressure. Combined with a specific new software and a new, unique ceramic regulation valve, DynamicFluid4 is offering precision in the application rate giving the best performance available on the market.


The sensors of DynamicFluid4 each have their individual task, but they will also work as backup for each other, and the regulation will continue. Regulation can be done manually.

Boom management system

The HARDI AutoSlant, AutoHeight and AutoTerrain systems will automatically control the boom This makes the job much easier for the driver, and the result will be a better spray application.


The system is known for the following features:

  • Robust and precise ultrasonic sensors
  • Option to choose between soil, crop or hybrid mode
  • Provortional valve for smooth movements (AutoHeight, AutoTerrain)
  • Slant, tilt and height correction (AutoHeight, AutoTerrain)
  • Slant and height correction (AutoSlant)

AutoTerrain works and reacts on both boom movements and twisting forces on the boom. This allows the system to be proactive and react on the cause more than on the symptom.

DELTA FORCE boom - Compact in transport - wide in field

DELTA FORCE is designed to be a large boom. The selection of features and the layout of the boom structure are targeted to perform at high driving speed and high performance at boom widths of 24-39 m. The result is a boom with many simple and strong solutions which together give a high-performing and reliable boom with a simple setup, low maintenance and a great design.


A very advanced, but yet simple centre part controls the movements of the DELTA FORCE boom. The five pendulum settings allow to adjust the boom performance, either to a pendulum, which follows the sprayer movements, or to follow the level of the terrain.


HARDI DELTA FORCE is available in:
3-fold: 39/27/15 m, 36/27/15 m, 36/24/13 m, 33/25/15 m, 32/25/15 m. 
2-fold: 30/15 m, 28/14 m, 27/14 m.

AutoSelect – Change nozzles "on the go"

WIth AutoSelect you have the possibility to change between 4 functions:

  • Spray with nozzle A
  • Spray with nozzle B
  • Spray with nozzle A and B
  • Auto mode – here AutoSelect can work with pre-defined pressure settings or working speeds.

Excellent at speed changes

If you need to run with big changes in speed, AutoSelect can automatically, and instantly change between two sizes of nozzles, so one nozzles work can be taken over by a larger nozzle, at higher speeds. This will result in a higher droplet quality and a better application.


Change of dose during the spray job

If you need to change dose in the field, this can be done by changing to a more suited nozzle on the go - without compromising the spray quality. You have the possibility to use 9 to 13 sections and maximum 8 nozzles per section. AutoSelect works with air pressure, if you have a pneumatic brake system on your tractor your air source is already provided. If not, an air compressor is available as an option.

DELTA FORCE – 25 cm Nozzle space


  • On-Center solution - the extra injectors are positioned between the 50 cm standard nozzle holders
  • Available for: NAVIGATOR 4000 / 5000 / 6000
  • Available for: COMMANDER: 4500 / 5000
  • DELTA FORCE: 27-36 m
  • 9 section EFC two-folded booms 27 / 28 / 30 m
  • 13 sections EFC three-folded booms 32 / 33 / 36 m
  • Stainless steel nozzle tubes as standard

The main argument for a distance of 25 cm is to reduce the height of the boom to 30 cm and to reduce the potential for spray drift. The low boom height requires a good boom management system. The best system on the market is the DELTA FORCE boom series along with HARDI AutoTerrain. The other advantage is a smaller nozzle VMD (volume median diameter) which increases the coverage.
