The preparation of the herbicide machine directly influences the quality of the work throughout the season. This guide provides a clear and practical overview of the steps required before the first application, as well as the essential checks after the storage period.
You’ll go through a structured, step-by-step process that helps ensure your equipment is ready for use from the first step in the field. The goal is a stable, safe and predictable setup so that you can start work as soon as conditions are favourable.
Why herbicide machine preparation is important
A correct pre-season check brings essential benefits:
-
prevents downtime
-
Improves application accuracy
-
reduces the consumption and waste of chemicals
-
extends the life of the equipment
In addition, maintenance planning and the use of readiness or upgrade kits contribute to long-term reliable operation.
Step-by-Step Guide to Herbicide Machine Preparation
Important: All tests should be performed using clean water.
1. Remove antifreeze from the system
If the herbicide machine has been protected with antifreeze during the winter:
Completely empty the system
Flush the tank, hoses, pump and ramp
Remove any residue or deposits
2. Inspect the pump
-
Check for any leaks or unusual noises
-
Control the pressure
-
Lubricate the components
-
Check the diaphragms and valves
3.Check the filters and nozzles
Clean all filters
Inspect nozzle wear
Ensure a uniform spray pattern
Replace damaged components
4. Inspect hoses and gaskets
-
Check for cracks or signs of aging
-
Control connections
-
Replace worn elements
5. Test valves and control systems
Check the operation of the valves
Control the pressure regulator
Test the flow meter
6. Calibrate the herbicide machine
-
Check the pressure
-
Measure nozzle flow rate
-
Adjust application rate (l/ha)
7. Inspect the ramp and mechanical components
Check for cracks in the structure
Control folding and stability
- Lubricate Moving Parts
Test suspension and ramp control
8. Check the electronic components
-
Test the controller
-
check GPS sensors and systems
-
Inspect cables and connectors
9. Take the final test
Perform a full clean water test
Check for leaks
Confirm the operation of all systems
Ready for the season
A full pre-season inspection ensures:
-
Consistent performance
-
Precise application
-
Safe operation
The time invested in preparation translates into fewer stops and better results in the field.
