Kverneland CTC
CTC – Cultivation from deep to shallow
Stubble cultivation, especially within a no-tillage or minimum tillage cultivation program, conserves soil structure and moisture and limits erosion. It is an operation which requires great consideration.
Highlights
Complete cutting, perfect mixing & levelling Low pulling force needed Reduced maintenance Versatile from shallow to medium Large performance by high speedDescription
Kverneland CTC is available in different configurations depending on the conditions of use, but also on the power ability:
The CTC has a well-organised tine arrangement over 3 tine rows with 270mm tine spacing or 4 tine rows with 200mm tine spacing. The capacity with long residues has been a focus during the design process ensuring optimum mixing and intensive cultivation.
The tine position has been optimised to ensure a smooth soil flow across the entire working width but also around the transport wheels. A maximum working depth of 30cm is possible. The high inter-row clearance up to a maximum of 150cm and the underbeam clearance of 870mm ensure blockage-free operation.
The following share equipment belongs to Triflex 700 and Share Bolt Tines:
- Reversible point 65
- Knock-On 80
- Knock-On 150
- Knock-On 250
- Knock-On 320
- Wings share 320
- Tiger 3 (70 carbide point)
- Carbide wings share 320
Features
- The CTC can be equipped with 3 rows of tines (spacing 270mm) and front working discs or with 4 rows of tines (spacing 200mm) ensuring optimum mixing and intensive cultivation.
- A maximum working depth of 30cm is possible
- The wing shares, when fitted, ensure that the entire working width of the machine is cultivated even when the machine is adjusted for shallow work.
- The high inter-row clearance up to a maximum of 150cm and the underbeam clearance of 87cm ensure blockage-free operation under any conditions.
- The outer wings are pre-loaded by hydraulic accumulators and can be adjusted to suit the various field conditions
Triflex 700: High stability at deep operations
The auto-reset Triflex tine uses the well-known Kverneland leaf spring system to ensure a high point pressure of 700kg in work and a smooth release curve when the tine hits an obstacle. The Triflex tine with narrow design and special shape reduces the pulling forces while ensuring a perfect penetration in most compacted soil. It is the perfect choice for deep loosening and working on heavier soil types strewn with stones.
The Triflex 700 tine can be equipped with different shares to adapt to different working depths and tasks. 7 types of share equipments are available with the patented Knock-on® system. It is the easiest way of changing parts on a cultivator, either to adapt the machine to the job to be done or to change wearing parts.
The new 70mm Tiger 2 is available on CTC. The special design ensures progressive and high penetration and requires low pulling force. The special shape of the carbide plate resist against aggressive stony conditions. All points are also available with Knock-on® deflectors.

For the CTC 3 rows, Kverneland has developed a front disc system to cut or incorporate crop residues in front of the cultivator tines.
The disc system has a centralized hydraulic depth adjustment with master slave cylinder system and individual rubber disc protection. This overload system allows the disc to follow the ground contour very well.
As the working depth of the disc section is limited to 5cm, the required pulling force is insignificantly low.
Front Mixing Disc (FMD)
The front mixing disc (FMD) option is the ideal equipment that avoid any boiling effect in front of the tines especially with short wheat straw. The FMD system has notched hollow discs which are ideal when working in high amounts of crop residues. The FMD system pre-mixes any straw standing on the top of the stubble to ensure thorough mixing by the stubbling tines for improved incorporation. The adjustment of the pressure can be done on the move from the cab hydraulically.
Front Cutting Disc (FCD)
The FCD system has notched straight discs which are mounted in front of the first row of tines. The FCD system is ideal when working in maize straw for example, where the disc is cutting the straw directly in front of the tines. The straw is cut to improve the flow of material and prevent the machine from blocking.
There is a full range of levelling equipment and rear rollers available for CTC
Levelling discs:
- Rubber spring loaded, to follow the ground and protect against stones
- Border discs as standard
Levelling tines
- Good levelling capacity and good following of the ground contour
Combi disc harrow:
- Combination of a single disc gang with all roller type
- Hydraulic depth adjustment by spacers
- Adjustable angle depending of the mixing intensity required
Cage roller Ø 550mm - 90kg/m
- 10 bars for a good loading capacity and operation in wet conditions
- Effective crumbling action
Double cage roller Ø 400mm (tube/flat) - 160 kg/m
- Good crumbling
- Precise depth control
Actipack Ø 560mm - 205kg/m
- The Kverneland Actipack roller displays its superb working qualities especially on medium to heavy soils and also in wet, stony and sticky conditions thanks to the independent skids and knives.
- The cutting discs break the larger clods whilst the adjustable knives cut the remaining clods resulting in optimal clod breakdown and fine seedbed preparation
Actiring Ø 540mm - 160kg/m
- The Actiring roller is a lighter variant of the Actipack, using the same frame structure and knife system.
- The discs have been replaced by a “V” profile ring, this is saving 60kg/m, which is of critical importance for reducing lifting requirements for mounted equipment.
- Actiring is not recommended in stony conditions
Actipress Twin Ø 565mm - 220kg/m without soil
- U-profile for high carrying /rolling capacity in light soils
- Clod breaking also in heavy conditions
- High and homogenous consolidation
- Weight when full of soil: 250kg/m
