Auto boom no license to speed

Author: Rachel Bowman | Date: 09 Aug 2013

New spray technologies such as auto boom height should not be seen as a license to travel at high speeds across uneven terrain, according to the Grains Research and Development Corporation (GRDC).

A new GRDC fact sheet, Spray height control, details how the feature can be used safely to maintain the spray nozzle at the correct height above the target area without risking spray drift.

The fact sheet includes these key points:

  • Auto boom height can help to maintain correct nozzle height above the target, which improves the evenness of the spray deposit and reduces spray drift through excessive boom height.
  • Operators should have realistic expectations of how an auto boom height system will perform.
  • Higher travel speeds and greatly undulating terrain may reduce the ability of a height control system to perform as intended.
  • Electronic auto boom height controllers require regular calibration and may not be suited to all boom designs.
