The Buchet apron-belt spreaders are agricultural machines designed for precise, uniform spreading of organic materials on plots, suitable for strawy manures and compost. They combine electronic control (control unit, DPA, weighing) and mechanical solutions (apron, beaters, knives, side flap) to ensure homogeneous distribution and reliable dosing.

Main features and innovations

• Spreading ensured by an apron conveyor and a half-belt composed of 2 chains and slats, preventing product slippage and ensuring regularity and precision.
• Beat ers positioned on the rotors (inclined at 20°) and knives, improving spreading for decomposed or light products; retractable beaters reduce power demand for strawy products (patented).
• Double-arm gate enabling effective leveling of the load top and rapid increase in loading rate.
• Control unit (patented) automatically managing spreading width and dosing.
• DPA (Proportional Dosage by Advance) to maintain hectare dosage regardless of speed and traction variations.
• Integrated weighing system (patented) eliminating density adjustments and errors linked to load level.
• Automated side flap for improved edge spreading along field borders.
• Low-floor body design with increased top width (2.20 m) for stability on slopes and ease of loading.
• Product protected by 4 invention patents.
• Certificates and distinctions: Sommets d'Or 2008, 2010 and 2011; eco-spreading certified since April 2014.

Technical characteristics / specifications

• Total spreading width (with 18 beaters tested by IRSTEA): 20 m.
• Effective width between passes: 14 m.
• Coefficient of variation (compost, IRSTEA tests): below 10% (standard requires < 30%).
• Extent (percentage of time spreading is uniform, IRSTEA tests): 95% on compost.
• Maximum deviation recorded between dose measured by IRSTEA and selected dose: never greater than 6% during tests.
• Top body width: 2.20 m.
• Rotors inclined at 20° (reduces product collapse during spreading).
• Patented elements: retractable beaters, control unit, weighing systems and other innovations (4 patents in total).
