The newly-launched trailed 450 (4.5m) and 550 (5.5m) He-Va Combi-Discs, provide growers with higher output, single pass machines for subsoiling, surface cultivation and consolidation. The two models can also be used as a subsoiler with the discs lifted out of work, a set of discs with the legs lifted up or as a complete one pass soil cultivator, all controlled from the cab. The depth of both the subsoiler legs and discs can be hydraulically adjusted from the tractor seat.
Importer Opico says the new models can be specified with either shearbolt or hydraulic auto-reset legs. There are seven hydraulic reset tines on the 450 Combi-Disc which subsoil to a 350mm depth, with quick-change replaceable points. The 550mm version has nine legs. Optional low-disturbance subsoiling tines and points are also available.
The 510mm diameter scalloped Sabre discs which follow the subsoiler legs cut and mix to a depth of 125mm. The two rows of opposing discs can be hydraulically adjusted and, as they are pushed deeper in the soil, the angle of the disc is automatically altered. This increases their aggressiveness to thoroughly mix and chop crop residues, says Opico. At the rear the land is consolidated by the 700mm V-profile press roller. Opico managing director James Woolway, reckons the new folding versions are ideal for rapid ground coverage, increasing the work rate without compromising on soil management. “They are equally at home 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,” he said.
Optional equipment includes a minimal disturbance disc opener, and a seeder kit can be added to plant cover crops or OSR while cultivating. The 450 and 550 models fold to a transport width of 2.61m and have automatic transport locks for safe and simple road transport. The folding trailed 450 hydraulic reset Combi-Disc retails at £50,339. The 550 version costs £62,638. Prices exclude VAT.
