Towed manure spreader EHV 20/13

verticals beaters2-axlewith speed-governed flow

Apron spreader with moving floor designed for precise, uniform spreading of organic products (manure, compost). The machine integrates automated systems to ensure dosing accuracy regardless of tractor speed or product characteristics.

Main features

• Apron conveyor combined with a half-belt (2 chains and slats) to drive the product and prevent slippage.
• Control unit (patented) to manage spreading width and dosage and to automate operations.
• DPA (Proportional Dosing to Advancement) to maintain hectare dosing despite speed variations or wheel slip.
• PESAGE (patented) integrated weighing system to eliminate density adjustment and reduce errors due to loading height or product density estimation.
• Retractable hammer elements (patented design) and knives to improve spreading of decomposed or light products while reducing power needs for strawy materials.
• Automated edge flap for optimized distribution at field margins.

Performance and recognition
Equipment tested by IRSTEA (formerly CEMAGREF) showing very favorable precision and uniformity results, and attested for eco-spreading. The concept is protected by several invention patents.

Technical specifications

• Type: apron spreader with moving floor
• Brand: BUCHET CONSTRUCTEUR
• Control unit: patented (manages width & dosage, displays spreading time, apron speed, trip count, weight, area spread, apron position, oil pressure, supply voltage)
• DPA: Proportional Dosing to Advancement
• PESAGE: integrated weighing system (patented)
• Hammers: complement knives, retractable (patented)
• Product drive system: apron conveyor + half-belt with 2 chains and slats (prevents slippage and ensures uniformity from start to finish)
• Harrow angle: 20° (reduces wall collapse in the hopper)
• Double-arm door: facilitates loading and leveling of manure
• Low floor / wide top hopper: top width 2.20 m (better stability on slopes, easier loading)
• IRSTEA test results (with 18 hammers): overall width 20 m; effective working width between passes 14 m; coefficient of variation < 10% in compost (norm < 30%); temporal uniformity 95% in compost; maximum deviation between measured dose and selected dose ≤ 6%
• Number of invention patents protecting the spreader: 4
• Attestation: eco-spreading attested since April 2014
