The share makes a groove in the ground and the slurry is then laid down by the injection hose that is just behind the share. As they are vibrating, these tines are more resistant to obstacles (stones, etc.) but offer a less regular working depth.
The working depth is adjusted by a central adjusting device on the gauge wheels.
Like the Terrasoc, the Terraflex injector can be used as a stubble plough or with an umbilical system.
