The onion topper VT 220 is used for an efficient haulm reduction and pre-harvest treatment before windrowing. The machine can be used for both front- and rear attachment. The rotating blade sets with their innovative geometry create a high suction effect, which sets up the haulm before it is cut off by the blades. The very sensitive height guidance of the onion topper causes the machine to run very smoothly and ensures a constant cutting height at all times. With the topper, type VT 220, beds can be treated within a track widths of 200 to 225 cm. The machine is designed for combination with the GRIMME windrower, Type WV.
