Lemken Koralin 9 Cultivator
The LEMKEN Koralin 9 KUA is designed for shallow, full-width cultivation while providing effective mechanical weed control. Combining three rows of cultivator tines with two rows of discs, the Koralin 9 KUA cuts weeds below the soil surface while mixing crop residue to encourage rapid decomposition. Available in working widths from 13.1 to 23 ft (4 to 7 m), it offers hydraulic working depth adjustment, generous frame clearance and multiple share options to suit changing field conditions. The result is a versatile cultivator that supports conservation tillage practices while maintaining consistent field performance.

What is the LEMKEN Koralin 9 KUA designed to do?
The Koralin 9 KUA is designed for shallow cultivation, mechanical weed control and residue management. It undercuts weeds across the full working width while mixing crop residue into the soil to promote decomposition.
How does the Koralin 9 KUA control weeds?
The machine uses three rows of cultivator tines fitted with shares that cut weeds beneath the soil surface. This full-width undercutting helps interrupt weed growth without relying solely on herbicides.
What role do the rear discs play?
Two rows of discs behind the cultivator tines improve residue incorporation, level the soil surface and help create a more consistent finish before the rear roller consolidates the seedbed.
Can the working depth be adjusted from the tractor?
Yes. The Koralin 9 KUA features hydraulic working depth adjustment, allowing operators to respond quickly to changing field conditions without leaving the tractor cab.
Why is the Koralin 9 KUA a good fit for Southern Alberta?
For producers adopting conservation tillage or looking to improve mechanical weed control, the Koralin 9 KUA offers shallow cultivation, effective residue management and adaptable working widths suitable for both medium and large grain operations.
