Used Combine Harvester Complete Thresher Cylinder

Thresher, concave and beaters: the heart of combine harvester threshing

On conventional combine harvesters, the thresher is a cylinder fitted with grooved beaters rotating at high speed above the concave, a curved grate also called a basket. The crop flow passes between the two: the beaters strike and rub the ears of grain, the grain passes through the basket, and the straw moves towards the straw walkers. The clearance between the thresher and concave and the cylinder speed are adjusted according to the crop type. A complete thresher includes the cylinder, its beaters, shaft, bearings, and pulley — the entire assembly delivered as one unit.

Complete thresher or beaters alone?

• Regularly worn beaters: a set of thresher beaters and mounts often suffices.
• Scored shaft or worn bearings: check the thresher shaft separately.
• Deformed concave: replace the concave and grate together with the thresher.
• Unstable speed: inspect the thresher variator and the thresher reducer.
• Warped cylinder, torn beaters, or cracked fastenings: a complete thresher avoids re-aligning each part individually.

Balancing and inspection: TMC Bejenne’s expertise

A thresher spins at several hundred revolutions per minute with a substantial mass: any imbalance wears bearings, strains the combine’s drive, and causes vibrations throughout the body. Before sale, our technical teams apply their expertise to balancing: they check the shaft’s straightness, the condition of the beaters and their mountings, and the cylinder’s star plates for cracks. Every complete thresher is original manufacturer’s equipment, never assembled from compatible parts. Since 1945, this technical know-how is backed by an 11-hectare site in Naintré, where our stock of threshing parts sits alongside 25,000 references of used tractor and combine harvester parts.

Combine harvester brands: used complete threshers

• New Holland : threshers for TX 34, 36, 64, 66, and 67, TF 44, 76, and 78, and CX 860 models.
• Claas Lexion 450, 600, and 760: original complete threshers, depending on disassembly availability.
• John Deere : threshers for models 1166, 1550, 2064, and 2066, from straw walker combines still common on farms.
• Laverda : threshers for L521 and 3600.
• Massey Ferguson : thresher for 7270.

Used vintage or small combine harvesters: finding the right thresher

For vintage combine harvesters, such as a Claas Dominator, new threshers often aren’t produced anymore: a used complete original manufacturer’s thresher remains the solution to keep the machine operational. Small combines with four or five straw walkers, common on medium-sized farms, have neither the width nor drum diameter of large machines made for vast fields: the cutter bar width already gives an indication. Provide us with the exact model, year of manufacture, operating hours if known, and the crop types harvested: cereal grains, rapeseed, maize, or sunflower all wear the beaters differently.

Thresher or rotor: threshing technologies

• Straw walker machines (New Holland TX, TF, and CX; John Deere W and T series): a transverse thresher and concave.
• Hybrid machines, such as Claas Lexion series 700: a thresher followed by separation rotors.
• Axial rotor machines, such as Case IH Axial-Flow or New Holland CR: no transverse thresher; see the used complete rotor.
• Threshing technologies vary between brands, and sometimes even within a range: when in doubt, our advisors provide purchase support based on the manufacturer’s plate and serial number.

Price of a complete thresher and combine harvester purchase

We do not display prices for this family: the cost of a complete thresher depends on brand, machine model, beater wear, and shaft condition. Compared to a new thresher, the price gap remains significant, and even more so compared to buying a replacement combine harvester. The "Request a Quote" button on each product page gives you an exact price, and our TMC Bejenne advisors offer purchase assistance to verify compatibility; shipping is done throughout France on pallet, or collection at Naintré depending on the thresher size.
