These tools were made when every district had a cornmill, needing concaves
able to handle hard, almost short grain kept in the stackyard for half the winter before threshing.
Because they are electronically controlled from the cab, the concaves can be quickly adjusted between crops.
Concaves with 6 mm slots are factory installed as standard.
Boasting a new patented technology, Concave
is set to take football to the next level and combines the most effective ever sweet spot with aunique system for protecting the metatarsal.
To celebrate the Concave
launch, People Sport has FIVE PAIRS to give away in a stunning competition.
The revolutionary new Concave
boots provide extra protection against the injury that has cursed a string of England stars, including David Beckham and Wayne Rooney.
