Heavy-duty screw
The screw is one of the most important parts of the mixer. That’s why Vermeer screws are built to last. The VS420 single-screw vertical mixer comes with standard 5/8-in (15.9-mm) abrasion-resistant AR200 screw flighting and a full set of hard-surfaced knives.

Durable tub
Heavy-duty, abrasion-resistant AR200 steel makes the Vermeer VS420 single-screw vertical mixer ready for years of use, various feedstuffs and numerous loads.

Efficient cleanout
Vermeer mixers are designed with three points of contact with the tub floor, including two bi-pulse legs and the leading edge of the screw. These points of contact help optimize cleanout of material from the tub during discharge.

4-point scale with Bluetooth connectivity
Operators can conveniently view the mixer's load weight on their smart device with Bluetooth connectivity. Hitting defined weight targets is more attainable with a 4-point scale versus a 3-point scale when feeding in multiple locations.

Low loading height
The low loading height of 110 in (280 cm) provides versatility among different operations with height restrictions during loading, feeding and storage.

Optional 2-speed gearbox
An optional 2-speed gearbox allows operators to tailor their mixing speed depending on the stage of the mixing and feeding cycle.
