For todays modern farms the demands for cultivation have changed. Tight time slots have to be balanced with higher machine performance. Restricted crop rotations call for an adaption in techniques that accomplish all requirements of modern crop cultivation. Kverneland proposes different configurations depending on the conditions of use, but also the power ability:
The CTC has a well-organised tine arrangement over 3 or 4 tine rows. The capacity with long residues has really been a focus during the design process ensuring optimum mixing and intensive cultivation. The row distance varies between 270mm and 200mm; the tine position has been optimised to ensure a smooth soil flow across the entire working width but also around the transport wheels.
• CTC with 3 tine rows and 270mm tine spacing
• CTC with 4 tine rows and 200mm tine spacing
|Model||Working width||No. of tines||Min./Max. HP|
|CTC 427||4.0m||15 (spacing 270mm)||145 / 300|
|CTC 420||4.0m||19 (spacing 200mm)||145 / 300|
|CTC 527||5.0m||17 (spacing 270mm)||175 / 350|
|CTC 520||5.0m||23 (spacing 200mm)||175 / 350|
|CTC 627||6.0m||21 (spacing 270mm)||205 / 400|
|CTC 620||6.0m||29 (spacing 200mm)||205 / 400|
Kverneland has developed a front disc system to cut or incorporate crop residues in front of the cultivator tines.
The disc system has central screw depth adjustment 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 tine 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.
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.
Tines can be combined with a variety of share systems allowing working depths between 5cm and 30cm.
