Used Combine Harvester Threshing Drum Star

Role of the Star in a Combine Harvester Threshing Drum

The threshing drum of a conventional combine harvester consists of a shaft on which several stars are mounted, spaced across the full width. These stars hold the threshing bars that beat the ears of grain against the concave to free the grain. The star transmits torque from the shaft to the bars and keeps their position stable with each rotation. A cracked, warped star or one with a worn bore can unbalance the entire assembly at high rotational speeds.

Threshing Drum Stars Available at TMC Bejenne

• End stars and intermediate stars for the threshing drum, depending on available models dismantled.
• Stars for threshing drums of conventional combine harvesters and pre-cleaning machines.
• Associated threshing parts: bars, pins, and mounting hardware.
• Used complete threshing drums when multiple stars are damaged.
• Drive components: threshing drum variators and threshing drum reducers.

Signs of a Worn Threshing Drum Star

The first symptom is often an abnormal vibration that changes with the drum speed. Next come threshing bars that regularly loosen, marks of rubbing against the concave, or irregular threshing across the machine's width. When stopped, check for cracks around the bar fixings, the flatness of each star, and the bore play on the shaft. A hit from a stone or foreign object can also warp a star without stalling the machine. On pre-cleaning machines like Claas Lexion models, also check the accelerator in front of the drum.

Older Combine Harvesters: Parts Still Available

For older combine harvesters, a threshing drum star can be difficult to find through manufacturer networks. Dismantling takes over: every machine dismantled on our 11-hectare site in Naintré supplies original parts stock, including for models no longer in production. A used star from the same model respects original dimensions, easing installation and drum balancing. If the star you need is not listed online, use the parts search form on this page to allow TMC Bejenne to check current stocks.

Checks Before Stocking

• Visual inspection of welds and crack detection around bar fixings.
• Flatness check to eliminate warped stars.
• Inspection of the bore and mounting splines on the shaft.
• Identification of the original machine, shown in each threshing part's description.

Correctly Identify the Star Suitable for Your Threshing Drum

Begin by noting the brand, model, and serial number of your combine harvester. Specify the star's position on the shaft — end or intermediate — the number of bars, and the drum width. Attach photos and, if possible, the reference number stamped on the part. Our specialized technicians compare this information with available stars before making any recommendation. After replacing a star, have the drum's balance checked, as it directly affects the longevity of the bearings and threshing drums.

How Much Does a Used Combine Harvester Cost?

• A used combine harvester typically ranges from €2,000 for an older heavily used model to more than €10,000 for a recent, reliable machine.
• Price varies according to brand, age, hours logged, and condition of the threshing system.
• A machine equipped with a recently serviced threshing drum and concave generally sells for more than one needing immediate repair.
• Ranges like Claas Lexion or John Deere Series T, renowned for their cutting power, command prices above market average.
• Comparing several specialized dealers, such as Reymond mat-agri, helps establish a fair price for a specific model before purchase.
• The cost of a threshing drum star or complete drum remains marginal compared to the machine’s overall price but directly impacts its resale value.
• Inspecting the threshing system prior to purchase prevents unpleasant surprises and costly repairs post-acquisition.
