When margins are tight and application windows are narrow, every dollar and every droplet need to work as hard as they can. John Deere’s unique portfolio of See & Spray products bring resource-saving precision to the field.
Technology evolution
John Deere has focused on taking farmers’ application from field level to plant level over the years. From field to broadcast, section control to ExactApply™ individual nozzle control, and now the next step – to artificial intelligence and machine learning. All See & Spray offerings work in conjunction with ExactApply nozzle control. They use a combination of cameras and processors to detect weeds before activating only the nozzles necessary to apply a burst of herbicide to the weed, achieving a hit rate comparable to traditional broadcast spray.
Data insights
How do you know See & Spray is doing its job? With the monitoring capabilities of John Deere Operations Center™ application and the G5Plus CommandCenter™ Display, you can track job quality and savings during and after application. These technology tools also offer weed pressure mapping, providing insights to make even better field management decisions. Weed pressure mapping only occurs when See & Spray is active during an operation.
Cover more acres more accurately and more consistently with ExactApply™ system
Fertilizers and crop protection products are too expensive to waste, and seed is too valuable to risk over- or under-treating. To help make sure your solution is getting to the crop at exactly the right rate and droplet size across a wider range of speeds, look to ExactApply nozzle control system.
The heart of the ExactApply system is a six-nozzle turret with multiple modes of operation to help maintain target rate and pressure. From the cab, operators can choose:
15-Hz pulse-width modulation (PWM) pulses one solenoid for more consistent pressure and droplet size over a wider range of ground speeds and application rates.
30-Hz PWM pulses both solenoids at 15 Hz for more thorough coverage during high-volume applications, like liquid fertilizer.
AutoSelect A/B mode automatically switches between two nozzles to maintain a constant spray pressure while you’re spraying conventionally.
Turn compensation mode decreases the spray rate on the inside of a turn while increasing the rate on the outside, ensuring consistent application across the entire width of the boom.
Individual nozzle control minimizes overlap by controlling spray application at the individual nozzle level, not in 2.4- to 3.35-m (8- to 11-ft) section widths.
By maintaining a target rate and pressure over a wider range of speeds, ExactApply lets you cover up to 20 more acres per hour (based on a 3.2-km/h [2-mph] increase in operating speed) with more consistent spray deposition, saving you input costs and preserving more of your crop’s yield potential.
Save product with pressure recirculation and product reclaim
Quality of application is critical. Avoid settling in the plumbing by keeping solution in motion with pressure recirculation, coupled with product reclaim and boom air purge. These features save precious time, product, and expense when rinsing and priming the boom while switching solutions
