Pre-production D-spec min-till drill version of the Sumo Trio delivers seed via tubes between the grooves left by the concave Trio discs.

These are then covered by the Multipacka, creating a min-till seed-bed. The standard Trio set-up has been adjusted to ensure that the Multipacka rings are in line with the seeding tubes to increase seed-to-soil contact.

Big savings in diesel are claimed – trial crops were sown using less than 30 litres/ha of fuel. From 2009, all Trios will be designed with the new disc-to-packer layout enabling the D-spec seeding kit to be fitted retrospectively.
