DynamicFluid4 (DELTA FORCE Boom only.)

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 Auto Height and Auto Terrain 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
  • Proportional valve for smooth movements (Auto Height, Auto Terrain)
  • Tilt and height correction (Auto Height, Auto Terrain)
  • Auto Terrain 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 90 - 132 ft. 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 center 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.
