How the Foam Marker System Works
The GrassWorks Foam Marker System integrates seamlessly with our Weed Wiper models to provide visual tracking during herbicide application. The system dispenses biodegradable foam droplets at set intervals, marking where the operator has already applied herbicide. These foam markers provide clear guidance for the next pass, ensuring even coverage and eliminating wasted effort.
Step-by-Step Operation:

Attach the Foam Marker System to the existing Weed Wiper assembly.

Fill the system with foam solution, which is biodegradable and designed for agricultural use.

Begin application—foam is dispensed at set intervals, creating visible markers on the ground.

Use the markers as a guide, ensuring no gaps or overlaps in coverage.

Foam dissipates naturally after application, leaving no harmful residue.
By visually marking treated areas, operators can focus on achieving optimal herbicide efficiency without needing expensive GPS tracking systems.
