Straw Chopper Machine Manufacturer Çetinkayalar: From Field to Harvest Since 1970
Cetinkayalar Agriculture has manufactured straw choppers in Konya, Turkey since 1970. The NCK-03 and NCK-06 series deliver automatic stem collection, chopping, and trailer loading in a single PTO-driven pass. No separate blower, no extra labor. Built on 55 years of field-tested engineering.
What Makes Cetinkayalar the Reference Straw Chopper Manufacturer?
Production History That Translates Directly Into Machine Reliability
Cetinkayalar does not design straw choppers for test conditions. The NCK series has been developed and refined on real harvest terrain — Central Anatolian dust, stony soil, dense maize stalks, fragile alfalfa leaves. Every detail in the pickup mechanism, drum design, and blade geometry reflects decades of field feedback from actual operators. That accumulated engineering is what separates a manufacturer with 55 years of production from one with five.
Three Models, One Standard: 2,200 kg/Hour Across the Range
- NCK-03 SM Standard — Automatic straw chopper: automatically collects wheat, barley, maize, oat and soybean stalks from the field, chops and loads into trailer.
- NCK-03 SM Knife System — Fine chop straw chopper: 54 specialized blades cut stalks at fiber level; produces consistent short-length fine chop straw for livestock digestibility.
- NCK-06 OM — Alfalfa and forage chopper: stationary hopper feeding for dried alfalfa, vetch and hay. Precision drum retains leaf content and protein value.
How Does the NCK-03 Automatic Straw Chopper Work in the Field?
From Stubble to Feed in One Pass
The NCK-03 SM follows the tractor through the field and picks up swathed or scattered crop residues via its 1,800 mm wide pickup unit. The operator drives. The machine collects, processes, and loads into the trailer continuously. At 2,200 kg/hour, winter feed stock is built in a fraction of the time manual collection requires.
Is a separate straw blower required?
No. The NCK-03 SM's integrated discharge mechanism blows processed straw directly into the trailer via an adjustable deflector. No separate straw blowing or loading equipment is needed. Collection, chopping, and loading are completed in one machine pass.
Why Is the Knife System Straw Chopper a Separate Category?
Fine Chop vs Coarse: A Measurable Difference in Livestock Performance
The NCK-03 SM Knife System produces a fundamentally different end product from a standard straw chopper. Its 54-blade drum cuts stalks at the fiber level rather than crushing them. The result is consistently short, soft fine chop straw — not the irregular coarse output of standard drum beaters. In dairy and livestock operations, fine chop straw reduces sorting behavior, decreases feed waste, and improves per-animal feed efficiency.
Maize stalk processing on the knife system
The NCK-03 SM Knife System handles dense maize and soybean stalks without clogging. For maize stalk processing, reduce tractor forward speed to match the higher stalk density. A tractor of 55 HP and above is recommended; 65 HP for sustained maize processing.
NCK-06 OM: The Alfalfa Chopper That Preserves Protein
Hopper-Fed, Leaf-Retaining Drum
The NCK-06 OM processes dried alfalfa, vetch, hay, and meadow grass via its 1,200 mm wide manual hopper. Its precision drum system chops forage without shedding the protein-rich leaves — the critical quality factor for dairy operations. Known in Turkiye as the forage patoz, it is the standard stationary forage processing machine for livestock farms that dry and store their own alfalfa.
⚠ MOST DEBATED TOPIC IN FARMING FORUMS
Straw Chopper Manufacturer Selection: Spare Parts or Price?
On Turkish and regional livestock forums, this question returns every pre-season. Newer manufacturers with lower list prices compete against established names. The field experience consistently settles the debate in one direction.
The critical data point: a straw chopper that breaks down mid-harvest does not cost its repair bill — it costs the entire feed production window for that section of field. Cetinkayalar's NCK-03 and NCK-06 spare parts — pickup fingers, blade sets, drum bearings — are in continuous production and stocked at the Konya facility and nationwide service network. For a manufacturer that entered the market five years ago and may not be active in ten, this continuity guarantee does not exist.
The practical forum consensus: choose the straw chopper manufacturer whose parts you can source in 48 hours, not the one with the lowest catalog price. Cetinkayalar's 55-year presence in the market is the basis for that 48-hour confidence.

FAQ — Frequently Asked Questions
1. What tractor HP is required for the Cetinkayalar NCK-03 straw chopper?
NCK-03 SM Standard: minimum 45 HP, optimum 55-65 HP. NCK-03 SM Knife System: minimum 55 HP, optimum 65-75 HP due to additional blade resistance. For maize stalk processing on either model, 65 HP and above is recommended to prevent drum speed loss during dense-patch feeding. All models operate at standard 540 rpm PTO.
2. Can the NCK-03 SM collect alfalfa from the field automatically?
Yes, technically. The 1,800 mm pickup unit collects field-laid alfalfa automatically. However, the pickup action causes higher leaf loss on alfalfa than on cereal stalks. For operations where alfalfa leaf retention and protein preservation are the priority — particularly dairy farms — the NCK-06 OM stationary model with manual hopper feeding delivers significantly better leaf retention. The NCK-03 SM is the better choice when collection speed matters more than leaf precision.
3. Where can spare parts for Cetinkayalar straw choppers be sourced outside Turkey?
Cetinkayalar ships spare parts internationally for export-market buyers. Standard spare parts packages — blade sets, pickup finger sets, drum bearing kits — are available for 2-3 seasons of maintenance and can be included in the initial machine purchase. For buyers in markets without a local Cetinkayalar distributor, contact the export sales team directly for current parts availability and lead times.
People Also Ask (PAA)
What is the difference between a straw chopper and a chaff cutter?
A traditional chaff cutter is a stationary, manually-fed machine that cuts straw into short lengths. An automatic straw chopper like the NCK-03 SM is a field-going machine that collects, processes, and loads straw in a single automated pass. The NCK-03 SM Knife System produces fine chop output equivalent to a chaff cutter — at 2,200 kg/hour and without manual labor.
Is Cetinkayalar a straw chopper manufacturer or a dealer?
Cetinkayalar is a manufacturer. All NCK series straw choppers are produced at the company's Konya, Turkey facility from in-house steel fabrication through final assembly. The company has been in continuous production since 1970 and exports to markets across Asia, Africa, the Middle East, and Europe. There is no outsourced production for structural or drum components.
What crops can the NCK-03 SM automatic straw chopper process?
The NCK-03 SM processes wheat, barley, oat, maize, and soybean stalks in standard configuration. For alfalfa automatic field collection, the NCK-03 SM works but with higher leaf loss than the NCK-06 OM stationary model. Both the standard and knife system versions handle the same crop range — the difference is in output chop length and fineness, not crop compatibility.
How long do Cetinkayalar straw choppers last?
The reinforced steel chassis and PTO-matched gearbox system of the NCK series are designed for 15-20 season operating lifespan with standard maintenance. Cetinkayalar's continuous spare parts production supports this lifespan: pickup fingers, blade sets, and drum bearings remain available throughout the machine's operating life. NCK models from the early 2000s are still in active operation — the most reliable service life reference a manufacturer can provide.
