Boom time for John Deere trailed sprayers
John Deere has announced two new high-end options for its M700 and M900 series trailed sprayers, which include six models with tank capacities from 2400 to 6200 litres and spray booms from 18 to 40m.
Previously only available on the high-specification M700i and M900i series models, the BoomTrac and LED field lighting options are designed to increase the performance and low operating cost benefits of using John Deere's mid-specification sprayers.
The established BoomTrac automatic boom levelling and height control system uses ultrasonic sensors to measure the height of the boom above the crop or soil.
If changes in the field or the target surface mean that the boom is no longer level, the system automatically adjusts it to maintain the optimum distance.
As a result, spray drift caused by excessive boom height is greatly reduced and spray coverage on the target is improved. In use, the operator can specify a desired boom height for each nozzle type or choose a different boom height depending on the application or field conditions.
The system is controlled via the tractor's in-cab GreenStar or CommandCentre display and does not require an additional control panel, which also reduces cab clutter and complexity. Designed specifically for John Deere sprayers, the control algorithm used for BoomTrac has been formulated to match the dynamics of the company's spray booms to provide improved performance.
Headland control modes
In addition, four headland control modes are available, including the ability to raise the boom to avoid obstacles, walls or hedgerows.
