He-Va has extended the width options of its single-pass Combi-Disc cultivator, with new 450 and 550 models offering 4.5m and 5.5m respectively to provide growers with higher output for subsoiling, surface cultivation and consolidation.

Subsoiler legs and disc depth can be hydraulically adjusted and the new models can be specified with either shearbolt or hydraulic auto-reset protection.

The discs lifted out of work on the move and there are seven hydraulic reset tines on the 450 Combi-Disc, which subsoil to a 350mm depth.

The 550 version has nine legs and comes with quick-change points, though optional low-disturbance subsoiling tines and points are also available.

The two rows of 510mm diameter scalloped Sabre discs cut and mix to a depth of 125mm. As they are pushed deeper in the soil the angle of the disc is automatically altered, which increases their aggressiveness.

At the back, there’s a 700mm V-profile press roller to give good consolidation to produce a weatherproofed finish.

Machines are equally comfortable being used for shallow stale seedbed preparation on 180hp tractors, or working up to 350mm deep moving the whole soil profile on a 450hp tractor, says importer Opico.

There is an optional minimal disturbance disc opener available, which slices through the surface layer in front of the subsoiling leg to reduce soil burst and ensure weed seeds are not brought up to the surface from depth.

There’s also a seeder kit option for drilling cover crops or oilseed rape while cultivating.

A folding, trailed 450 Combi-Disc with hydraulic reset comes with a £50,339 ticket price, while the 550 retails at £62,638.
