Crop Maintenance Technologies

Our crop maintenance technologies help you in many areas. Whether it is to control your production costs, increase productivity, optimize input placement, document your operations, reduce operator workload and accident risks, control herbicide resistance, reduce your environmental footprint, and much more. For your sprayer, spreading truck or other equipment, we have the solutions that will meet your company’s needs.

Automation and guidance

When it comes to applying pesticides and fertilizer or performing mechanical maintenance, our automation and guidance solutions give you precision and peace of mind by reducing the operator’s workload and the risk of error. What’s more, because work windows are often very tight, our solutions help you increase your productivity to optimize your opportunities. By strictly controlling the inputs you apply, you reduce over-application/under-application, ensure precise placement of your inputs, and obtain an optimal yield.

Input control

Our input control solutions ensure that you apply the target dose evenly regardless of your speed. In addition, combined with section control, they help you reduce overlap and skips. 

Control your costs, eliminate under- or over-application and reduce your environmental impact with our solutions. 

Maintenance technology


Camera guidance (AutoTrac™ Vision) allows you to come back to work in the field without damaging your crop. A camera is installed on your sprayer, cultivator or tractor and steers the equipment to optimize the pass.


A set of sensors (RowSense™) installed on the sprayer or cultivator determine the position of the plants to avoid damaging them during the pass. 

Mobile Weather

Mobile Weather technology monitors certain critical environmental constants (air temperature, wind speed/direction, relative humidity, and delta T) for you in real time as you apply your products. Having this information at your fingertips helps you make decisions quickly to optimize the effectiveness of your products and avoid drift. In addition, when combined with a compatible display, you can document this information for future viewing.

ExactApply™ : Every droplet counts

exact apply
  • ExactApply™ technology helps you optimize your spraying by independently controlling each of your nozzles. This ensures that you apply exactly the right dose and droplet size through a wide range of speeds. 
  • In addition, this technology helps you save money by eliminating over-application due to overlap. It also helps you optimize your yield potential. With turn compensation, the nozzles on the inside of the turn will have a lower flow rate and those on the outside will have a higher flow rate to avoid under/over application. 
  • The AutoSelect A/B feature allows you to automatically switch between two nozzles to maintain a good spray pattern and constant pressure. 
  • ExactApply™ also allows you to apply high doses, with an industry-exclusive rate of up to 468 L/ha at 24 km/h. 
  • For those who perform night work, LED lights allow you to monitor your spray pattern and react quickly if there’s a problem.

Direct Injection

As solution tank mixes become more complex, operators need a better way to manage the various products they are mixing. The integrated direct-injection system provides an additional carrying capacity for raw chemicals and allows you to inject one, two and even three products directly into the boom. 

The direct injection system helps you: 

  • Save time by providing quicker product/solution changeovers 
  • Rinse the boom faster 
  • Reduce the risks associated with using multiple chemicals 

Solution Command System

The Solution Command System makes it quick and easy to activate loading functions.

Pressure recirculation and product reclaim 

Spraying quality is critical. The pressure recirculation system ensures that the boom is always loaded, which means that your boom is ready to work at all times compared to a conventional system that requires you to open sections and add product to load the boom. 

This helps you: 

  • Save time and chemicals 
  • Reduce the potential for crop damage from chemical residue 
  • Have a consistent distribution from one end of the boom to the other 
  • Decrease nozzle blockages by increasing product agitation 
  • Keep the suspended product mix in the boom 
  • Benefit from an improved boom rinse 

HarvestLab™ Manure

HarvestLab™ Manure measures (over 4,000 measures/minute) nutrient levels in real time during liquid manure application. This data (N, NH4,P, K, Dry matter) is recorded for documentation purposes. 

In addition, when combined with a compatible John Deere tractor, the system will even be able to manage the tractor’s running speed to ensure the target rate of liquid manure is always applied. 

Advantages include: 

  • No negative impact on the consistency of liquid manure distribution from one end of the boom to the other 
  • Much faster response time 
  • Much more stable application control
