Towed manure spreader EHV 11/7

verticals beaterswith speed-governed flowcompost

Apron-belt spreader designed for precise, uniform spreading adapted to organic products (manure, compost). This next-generation spreader integrates automation and systems focused on dosing accuracy and spreading consistency.

Main functions and components

• Control unit (automated management of spreading parameters: width and dose).
• DPA (Proportional-to-groundspeed Dosing) ensuring hectare dose consistency regardless of speed or slippage.
• Weighing system (eliminates density setting and reduces errors due to loading height).
• Hammers in addition to knives, retractable to adapt to decomposed or strawy products.
• Automated edge flap for improved material distribution on field borders.
• Drive belt (half-belt) composed of 2 chains and crossbars and accompanying apron to prevent product slippage.

Performance, patents and certifications

• Four invention patents protect key functions (hammers, control unit, weighing, etc.).
• Eco-spreading certified since April 2014.
• Awards: SOMMETS D'OR 2008, 2010 and 2011.

Test results (summary)

• IRSTEA tests (formerly CEMAGREF) validating spreading regularity and precision.

Technical characteristics / specifications

• Overall working width: 20 m.
• Width between passes: 14 m.
• Coefficient of variation in compost: below 10% (standard: must be < 30%).
• Extent (percentage of time spreading is regular) in compost: 95%.
• Maximum observed deviation between measured dose and selected dose: never above 6% during tests.
• Inclined beaters: 20° (reduces collapse and improves regularity).
• Double-arm door: facilitates smoothing and progressive loading.
• Top box width: 2.20 m (low floor for stability on slopes and easy loading).
