Threshing Machine by Cetinkayalar
Threshing Machine by Cetinkayalar: NCK Series
The Cetinkayalar threshing machine has been manufactured in Konya, Turkiye since 1970. Over five decades of uninterrupted production, the NCK series has grown from a single PTO-driven wheat thresher into a complete seven-model lineup covering wheat, barley, maize, chickpeas, lentils, groundnuts, and watermelon seed — at a rated capacity of 2,200 kg per hour across the full range. This article covers every NCK threshing machine model, its engineering foundation, and why the Cetinkayalar brand continues to be chosen by farmers and agribusinesses across four continents.
For any farmer evaluating a thresher machine, the starting point is a simple question: which machine will still be running in year fifteen, with parts available and a manufacturer that answers the phone? That question is what built the NCK series — and what keeps it in the field long after the competition has moved on.
What Is the Cetinkayalar Threshing Machine?
The NCK Series: Seven Models, One Manufacturing Standard
The Cetinkayalar threshing machine lineup — the NCK series — is not a catalog built around a single platform with cosmetic variants. Each model in the NCK range was engineered to address a specific operational requirement: farm scale, crop type, automation level, and labor availability. What they share is a common manufacturing standard: impact-rated steel chassis fabricated at the Konya facility, PTO-driven drum systems at standard 540 rpm, and a continuous spare parts supply that has never been interrupted since 1970.
Farmers who buy a Cetinkayalar threshing machine are buying into a parts ecosystem, not just a machine. The NCK-01 models purchased in the late 1990s still have every wear item available in stock. That is not a marketing claim — it is the operational reality that defines long-term value in agricultural equipment.
NCK-01: The PTO Threshing Machine That Defined the Lineup
Shaft-Driven Power — No Belt Loss, No Slip
The NCK-01 threshing machine series is the entry point of the Cetinkayalar range and the most widely deployed model globally. It connects directly to the tractor PTO shaft — no belt drive, no power loss between the tractor and the drum. This direct mechanical connection delivers consistent drum speed under load, which is the single most important variable in clean grain separation on a wheat thresher or barley thresher.
Three variants serve different discharge preferences: the Bagging Type, where grain is collected into sacks at the machine outlet; the Auger Type, where a screw conveyor transfers grain to a trailer without manual lifting; and the Gear Box (HMS) Type, where an integrated gearbox absorbs tractor speed variation and maintains stable drum RPM — the critical advantage when operating with older or variable-output tractors.
Which NCK-01 model is the right wheat thresher for your farm?
The Bagging Type is the most economical entry into the NCK range and the correct choice for farms with available manual labor and limited budget. The Auger Type eliminates the physical demand of sack lifting while keeping labor requirements low. The Gear Box HMS Type is the correct choice when operating with a tractor that shows RPM variation under load — which is common with older or high-hour machines. If the tractor's PTO output is stable at 540 rpm under load, the standard shaft-driven models are the better value.
Multi-Crop Configuration on the NCK-01 Threshing Machine
The NCK-01 series is a multi-crop threshing machine. Factory configuration is wheat and barley. With the correct sieve kit and pulley adjustment — a 45-60 minute changeover — the same machine handles chickpeas, lentils, vetch, cumin, and oats. Cetinkayalar supplies crop-specific sieve kits for all configurations as accessory items and provides written configuration documentation for each crop transition. The NCK-01 HMS Gear Box variant is the recommended model for chickpea and lentil configuration due to its superior drum speed stability on the different resistance profiles of pulse crops.
NCK-02: The Mobile Hopper Threshing Machine
750 kg Hopper — Labor Eliminated at the Point of Collection
The NCK-02 threshing machine introduces a 750 kg integrated hopper that collects threshed grain as the machine moves through the field. Manual bagging is eliminated entirely. Two operators handle the entire harvesting process — one driving the tractor, one monitoring the machine and managing trailer logistics. For farms where labor cost is a significant operating expense, the NCK-02 delivers a measurable reduction within the first season.
Double Elevator Recycling: The Correct Tool for Red Lentils
The NCK-02 Double Elevator variant adds a second recycling elevator that returns uncleaned grain from the primary sieve back to the drum for re-threshing. This feature was developed specifically for red lentils — a crop where pod-grain separation is incomplete on a single pass through most standard threshing machine designs. The Double Elevator configuration ensures zero grain loss on red lentils by continuing to process material until separation is complete. It is also the preferred configuration for any difficult-to-separate pulse crop where a single-pass thresher machine delivers unacceptable waste levels.
NCK-04: The Automatic Pickup Threshing Machine
From Swath to Hopper — Fully Automatic
The NCK-04 threshing machine is the most automated model in the standard NCK range. It combines the mobile hopper system of the NCK-02 with an automatic pickup mechanism that collects swathed crops directly from the ground — eliminating the need for any ground-level labor. Cut and windowed crops are fed directly from the field into the drum without manual intervention. The 1,000 kg hopper — double the capacity of the NCK-02 — extends the continuous run between trailer unloading stops.
The NCK-04 is the correct threshing machine for farms where labor cost is the primary driver of equipment investment decisions. The return on investment calculation is straightforward: how many seasons of labor savings does it take to offset the price premium over the NCK-02? On farms operating 150+ hectares per season with rising labor costs, the answer is typically three to four seasons.
NCK-04 Double Elevator: Maximum Automation, Maximum Purity
The NCK-04 Double Elevator combines full automatic pickup with the recycling elevator system of the NCK-02 Double Elevator. It is the highest-specification standard model in the NCK threshing machine range: fully automated collection, full labor elimination, and zero-loss grain separation on difficult crops. For large-scale operations where both automation and clean separation quality are required simultaneously, the NCK-04 Double Elevator is the definitive solution.
NCK-05 and NCK-07: Specialty Threshing Machine Models
NCK-05 FM: The Groundnut Thresher
The NCK-05 FM is a purpose-built groundnut thresher machine — not a modified general thresher. Standard threshing machine drum speeds of 800-1,100 rpm generate peripheral speeds of 20-28 m/s. Groundnut shells crack and shatter at anything above 8-12 m/s. The NCK-05 FM's drum is calibrated to operate within the groundnut shell's safe impact threshold, separating pods from vines without shell damage. The integrated soil and root separation system — absent from any standard threshing machine — removes the soil and root contamination that is inherent in groundnut harvesting. The NCK-05 FM is not an optional configuration of another model; it is a standalone machine for a crop that standard farm thresher equipment cannot handle.
NCK-07 KM: Watermelon and Pumpkin Seed Harvester
The NCK-07 KM operates at a rated capacity of 20,000 kg per hour — ten times the rated throughput of the standard NCK threshing machine range. It is designed for industrial-scale watermelon and pumpkin seed processing. This machine addresses a specific market segment with very few competing products: high-volume specialty seed processing that requires industrial throughput at agricultural field conditions. For operations producing export-grade watermelon or pumpkin seed, the NCK-07 KM is the only Cetinkayalar model with this throughput specification.
Why Cetinkayalar Threshing Machine Quality Starts at the Steel
In-House Steel Fabrication: No Outsourced Structural Components
At the Cetinkayalar Konya facility, chassis and drum components are fabricated from impact-rated steel plate on in-house production lines. The company does not purchase finished sub-assemblies and bolt them together. Raw material enters the facility; finished machines exit. This integration means quality control begins at material selection, not at incoming inspection of externally produced parts. The weld quality, plate thickness, and structural tolerances are set and maintained by Cetinkayalar's own production team — not delegated to a subcontractor whose standards may differ.
This manufacturing approach is why NCK threshing machine chassis failures are rare and why the structural warranty coverage is meaningful rather than nominal. A machine built from in-house steel to in-house tolerances can be warranted with confidence. A machine assembled from third-party structural components cannot carry the same guarantee.
Konya: Where Threshing Machines Are Tested on Real Terrain
The Konya plateau is the center of Turkey's largest wheat and pulse production area. Cetinkayalar's threshing machine designs have been developed and tested on actual harvest terrain — stony soil, sandy surfaces, temperature extremes from -10°C to +42°C, and crop varieties ranging from wheat to chickpeas to red lentils. Every design decision in the NCK series reflects decades of field feedback from operators running machines in these conditions. This is the engineering advantage of proximity: not laboratory simulation, but real field performance across real crop seasons.
Fifty-Five Years of Uninterrupted Spare Parts — What It Means for Buyers
The Cetinkayalar spare parts policy is unusual in agricultural equipment manufacturing: parts are kept in production for every NCK model ever manufactured. NCK-01 and NCK-02 models from the 1990s still have drum bearings, sieve frames, elevator chains, and belt sets available in stock. For buyers in export markets where sourcing parts for discontinued models is a consistent operational problem, this policy removes the single largest long-term risk in threshing machine ownership. A machine that cannot source a replacement drum bearing set in year twelve has zero residual value; a machine whose manufacturer has kept that bearing set in production since 1990 retains both operational value and resale market value.
⚠ MOST DEBATED TOPIC IN FARMING FORUMS
Can One Threshing Machine Genuinely Handle All Crop Types — or Is Multi-Crop a Marketing Claim?
This debate appears on agricultural equipment forums in Turkey, the Middle East, East Africa, and South Asia with consistent regularity. The question is legitimate: thresher machine manufacturers routinely claim multi-crop capability in their product descriptions, and just as routinely, farmers report that the 'multi-crop' designation in practice means 'wheat and barley with one other crop if conditions are perfect.'
The Cetinkayalar NCK series position on this is specific, not general. The NCK-01, NCK-02, and NCK-04 threshing machines are genuine multi-crop platforms for cereal and pulse crops — because they ship with a standardized, crop-indexed sieve and pulley changeover system with documented configuration sheets for each crop. The changeover from wheat thresher configuration to chickpeas takes 45-60 minutes. The changeover from wheat to red lentils takes the same time. These are tested, documented, field-verified transitions — not theoretical compatibility claims.
Where the forum discussion consistently lands is on the distinction between genuine crop flexibility and marketing-grade flexibility. Genuine flexibility means: here is the exact sieve aperture, pulley ratio, and fan speed for this crop, with a kit that allows you to make that change in under an hour. Marketing-grade flexibility means: 'with some modifications' — which in practice translates to 'with modifications we cannot specify and parts we do not supply.' The NCK series falls into the first category. Buyers evaluating any threshing machine for multi-crop use should ask the manufacturer to specify, in writing, the exact configuration for each crop they intend to harvest.
The forum consensus is consistent: a threshing machine with documented, supplier-supported multi-crop configuration is worth paying a premium for over one that lists crops in the product description without the supporting kit and documentation. The NCK series' sieve kit range covers wheat, barley, oats, maize, rice, chickpeas, lentils, millet, vetch, and cumin — each with a written configuration reference included at point of sale.
Cetinkayalar Threshing Machine Export: Built for Global Field Conditions
Asia, Africa, Middle East, Europe — The Same Machine, Documented for Each Market
The Cetinkayalar threshing machine exports to markets across Asia, Africa, the Middle East, and Europe from the same Konya production facility. Export orders include English-language technical documentation, CE conformity for European market requirements, and crop-specific configuration kits sized for the target market's primary crop varieties. The machine itself does not change between domestic and export orders — the documentation, configuration kits, and spare parts packaging are tailored to market requirements.
For export buyers in markets where local thresher machine service infrastructure is limited, Cetinkayalar offers spare parts packages scaled to 2-3 seasons of standard maintenance at point of sale. This pre-purchased spare parts approach eliminates the sourcing uncertainty that is the most common operational problem for buyers running imported threshing equipment in markets without local dealer networks.
Farm Thresher to Industrial Seed Harvester: One Manufacturer, Full Range
The NCK range covers the full spectrum from small farm thresher to industrial seed harvester in a single product family from a single manufacturer. The NCK-01 is the starting point for operations of 20-50 hectares. The NCK-07 KM is the endpoint for industrial watermelon and pumpkin seed processing at volumes that no standard farm thresher machine can address. Between these two endpoints, the NCK-02 and NCK-04 platforms serve the full range of medium and large farm operations with escalating automation levels. Buyers who start with an NCK-01 and grow into an NCK-04 or NCK-02 are adding to a parts ecosystem they already know — not switching to a different manufacturer's infrastructure.

FAQ — Frequently Asked Questions
1. What is the rated capacity of the Cetinkayalar threshing machine?
All standard NCK series threshing machines — NCK-01, NCK-02, and NCK-04 — are rated at 2,200 kg per hour. This capacity applies to wheat thresher configuration under standard field conditions. The NCK-05 FM groundnut thresher operates at the same 2,200 kg/hr rated throughput on groundnut. The NCK-07 KM watermelon and pumpkin seed harvester is rated at 20,000 kg per hour — a dedicated industrial-scale machine outside the standard NCK range.
2. What is the thresher machine price range for the NCK series?
Thresher machine price in the NCK series varies by automation level and model configuration. The NCK-01 PTO Bagging Type represents the entry price point; the NCK-04 Double Elevator Automatic Pickup represents the top of the standard range. Cetinkayalar does not publish catalog prices online as pricing varies by market, configuration, and sieve kit package. For current thresher machine price information, contact Cetinkayalar's authorized export sales team with your specific model requirements and target delivery market.
3. Which NCK threshing machine model is correct for a small farm?
For small farm operations of 20-60 hectares, the NCK-01 HM or NCK-01 HMS threshing machine is the correct starting point. Both are a small threshing machine in terms of operational footprint — PTO-driven, tractor-mounted, no trailer required for the threshing unit itself. The HMS Gear Box variant adds drum speed stability for farms using older tractors with variable PTO output. If labor elimination is the priority even at small farm scale, the NCK-02 Single Elevator provides the hopper system at the next price point.
