Spading and subsoiling in a single operation!. Out in the field, there is a need for a cultivator that can easily be combined with a spader at low cost and with less tractive force. It has been found in practice that compaction occurs deeper than the surface soil under some conditions. You want to break up this often poorer subsoil but not to mix the surface soil. It is important to create so-called “cracks” so that air and plant roots can penetrate to deeper soil levels. There is also no longer hard pan that retains water and directs it upwards (capillary action) and downwards.

The machine is designed to be mounted close to the tractor, with the spader coupled very closely to the ‘Culter’ without the tines making contact with the spade shaft when bolts shear. The Culter 3.0 makes it possible to rip and spade, just to rip or just to spade. The machine is very versatile in this regard. The Culter can also be combined with other tools such as a loose roller, power harrow, rotovator or disc harrow.

The many features offered by the Culter 3.0 make the machine unique in relation to other machines on the market. The Culter 3.0 comes with 6 straight Culter tines as standard. These tines have been designed with the aim of requiring minimal tractive force, creating optimal yields and less costs per hectare. The Culter tines are made of high tensile steel with easily replaceable wear parts.

They ensure even lifting (and breaking) of the subsoil without unwanted displacement of the upper layer and with a uniform soil profile across the entire working width. As a result, oxygen penetrates the soil and facilitates capillary action.

The Culter is sand-blasted as standard and then powder-coated for optimal service life. It also has a hydraulic system with a lifting capacity of 3,000 kg.

The machine has a maximum working depth of 60 cm and is suitable for tractors up to 400 hp. Of course it is also possible to work with fewer Culter tines. These can easily be mounted at different separations.

JNC 'Advantages of the JNC rotovator:

  • The rotovator does not feature a chain case on the side: the machine width is therefore the same as the working width.
  • The construction of the rotovator is very robust, with a central drive, and therefore little maintenance and wear.
  • It is possible to remove the protective caps, thus providing access from above to inspect and maintain the blades.
  • The machines are supplied with supporting wheels as standard, as this ensures their stable operation and proper depth control.
  • Since the machine is not fitted with shoes on the side, it won't drag plant residues while maintaining a very even working depth (no 'tile' effect).


The special position of the blades ensures that there is no compaction (plough-pan). The gear box is suitable for 540, 750 and 1000 rpm. Thanks to the absence of a chain case on the side, the cultivated strips overlap smoothly, without gullies or ridges in-between. The rotovator is fitted with continuous side panels extended far behind and heavy tailgates. This keeps the soil closed off, ensuring perfect, plane tilling. A number of accessories are available, such as cage and bar rollers or smooth rollers. Their height adjustment can be manual or hydraulic.

Overtop rotovator:
The JNC OTL or OTZ overtop rotovator is one of a kind. The rotovator rotates against the direction of travel, projecting the soil upwards and backwards against a bar rack, burying the crop residues underneath the furrow. The soil projected through the bars then covers the crop residues, thus producing a nice, clean seed bed. The OTL and OTZ machines are not suited for work in stony conditions.

All machines are available with the so-called JAP blades (self-cleaning) and JAP blades are fitted as standard in the overtop model.  Other working widths or models are available upon request. By default, all models are provided with support wheels (except overtop rotovators) and a PTO with shear pin protection.
