He-Va has launched wider, folding versions of its trailed Combi-Disc single-pass cultivator.
To achieve higher output, the new 450 and 550 models offer wider working widths of 4.5m and 5.5m respectively, and offer subsoiling, surface cultivation and consolidation in one-pass.
Distributed in the UK by Opico, the new models can be specified with either shearbolt or hydraulic auto-reset legs. Depth of both the subsoiler legs and discs can be hydraulically adjusted from the tractor seat. This allows the operator to make independent adjustments on the move for accurate control of cultivations, says the manufacturer.
It 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.
There are seven hydraulic reset tines on the 450 Combi-Disc which subsoil to a 350mm depth, with quick-change replaceable points. The 550 version has 9 legs. Optional low-disturbance subsoiling tines and points are also available.
The 510mm diameter scalloped Sabre discs which follow the subsoiler legs will 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, increasing their aggressiveness.
There is an optional minimal disturbance disc opener available. This 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.
A seeder kit can also be added to plant cover crops or oilseed rape while cultivating; the seed is distributed behind a soil mat to ensure soil throw from the discs does not disrupt seed distribution.
Both new models fold to a transport width of 2.61m and have automatic transport locks for safe simple road transport, says the manufacturer.
The new folding trailed 450 hydraulic reset Combi-Disc retails at £50,339 plus VAT, with the 550 version retailing at £62,638 plus VAT.
