Used agricultural grain unloading tubes: all brands available

The grain unloading tube ensures the flow of grain from the hopper to the outside of the machine. A seemingly simple part, but whose failure can abruptly stop the harvest in the field.

At TMC Bejenne, our inventory covers a wide range of configurations: varying diameters, different lengths, straight or bent models according to combine harvester designs. Each tube comes from dismantled machines and is inspected before sale.

Unlike household water inlets or Miele drain hoses, agricultural tubes must meet very specific mechanical requirements: impact resistance, vibration-tight sealing, and compatibility with the unique grain transport systems of each manufacturer.

Specify the exact model of your combine to quickly identify the corresponding reference in our catalog.

Our grain unloading tubes by combine brand

• New Holland is among the most represented brands in our stock of used grain unloading tubes.
• For John Deere, tubes adapted to models 1075 and 2066 have already been listed and sold on our site.
• Claas tubes cover multiple generations of combine harvesters with distinct hopper geometries.
• Case IH and Laverda also have references in stock, depending on incoming dismantled machines.
• Each brand commands specific specifications: tube length, outlet angle, and insertion diameter vary significantly.
• Providing the exact brand and model number avoids assembly errors when ordering.

Drain hoses for CLAAS, JOHN-DEERE, and CASE IH

CLAAS combines, like the Lexion or Tucano series, have drainage tubes with specific inclination angles, directly related to the inclined design of their hopper floors. An incorrect outlet angle is enough to cause repeated blockages.

At John Deere, S and T series have different insertion diameters depending on the production years, making vintage verification essential before any order.

For CASE IH, especially Axial-Flow models, the tube length directly affects the proper positioning of the grain flow to the elevator. Providing the manufacturer's reference or the machine’s nameplate remains the most reliable way to obtain the exact part.

Drain tubes for NEW HOLLAND and LAVERDA

• New Holland, with its CR and CX series, uses drain tubes with specific fittings that differ from other manufacturers.
• On New Holland TC5 and TC5.90 models, the drain tube has a straight profile, which is uncommon on other brands.
• LAVERDA, an Italian brand integrated into the CNH group, shares some hopper designs with New Holland.
• LAVERDA M series references may be compatible with certain New Holland tubes, pending prior verification.
• TMC Bejenne regularly lists New Holland tubes from fully dismantled machines, ensuring their original condition.
• The serial number engraved on the New Holland machine allows precise identification of the expected tube generation.
• Contacting TMC Bejenne directly is the quickest way to confirm the availability of a LAVERDA tube.

How to check compatibility of your drain hose?

Three elements should be measured directly on your machine: the tube’s internal diameter, its overall length, and the outlet angle. An error in any of these parameters can render the part unusable, even if the brand matches.

The nameplate on your combine harvester shows the full serial number, which links your machine to a specific generation. For example, two John Deere S series made five years apart may use tubes with different insertion diameters.

If you no longer have the original manual, take several photos of the faulty tube from different angles before contacting our team. This approach avoids unnecessary back-and-forths and speeds up identifying the correct reference in our stock.

How to clean a used grain unloading tube?

Before installing a used grain unloading tube on your combine, thorough cleaning is essential. Residues of grain, dust, and moisture can compromise the seal of the fittings or cause blockages upon first use.

Start by blowing out the inside of the tube with an air compressor set between 4 and 6 bars. This step loosens dry deposits lodged on the walls without risking residual moisture.

For stubborn build-up, wiping the inside with a cloth soaked in soapy water usually suffices. Then rinse with clean water and let it air dry completely, ideally for 24 hours, before installation.

Also check the condition of the ends: a slight sanding with fine sandpaper is enough to refresh insertion edges and ensure a clean fit with the machine’s connectors.
