I have long been looking for a 6m syringe with proper usage. Since I did not find anything, I have the Monsoon TRITON 200 converts, spiced up adapted from LS11. They consumed, calculated on the working width, the same as the big standarts injection (0.2 liters per meter working width).
This makes them ideal as a front end device in a fertilizer Sähkombination.
Working width: 6 m
Fertilizer tank: 1150 l
Maintenance Cost: 10 € / day
Cost: 4000 €
