Product Description

SEPPI M. | Lightest Flail Mower | Model H3 85 | Working Width 33" Inches | Machine Size 5 To 7 Ton | For Excavators

DESCRIPTION

Precision engineered for maximum versatility, the Seppi H3 85 Flail Mower is the lightest excavator-mounted mulching head in the Seppi M. lineup purpose-built for 5 To 7 ton mini excavators. Featuring a 33" working width, heavy-duty AR400 wear-resistant steel construction, and a mechanically floating mount, the H3 85 delivers smooth, even mulching across challenging terrain like riverbanks, roadside edges, and tight-access green spaces.

Whether you're a contractor, landscaper, municipality, or farm operator, this hydraulic flail mower offers the maneuverability and toughness required for small-to-mid scale vegetation management, with a powerful triple helical rotor that shreds through grass and brush up to 1 inch in diameter.

This compact yet rugged unit is compatible with a wide range of excavators and hydraulic systems thanks to a customizable hydraulic motor setup and universal interface design. Designed with low-maintenance V-belt transmission and an adjustable support roller, the Seppi H3 85 flail mower is the perfect blend of mobility, durability, and performance.

Key Features

  • Engineered for 5–7 ton mini excavators, the Seppi H3 85 flail mower is perfectly balanced for compact machines, delivering optimal performance without overloading your boom or hydraulics.
  • Features a 33-inch working width, making it ideal for clearing narrow paths, ditches, and tight-access green spaces in a single efficient pass.
  • Built with a high-tensile AR400 steel chassis, offering exceptional wear resistance in harsh terrain and extended machine life for professional operators.
  • Compatible with hydraulic flow rates from 9–18 GPM, supporting a broad range of excavators while maintaining powerful mulching output.
  • Equipped with a triple helical rotor and SMW flails, designed to mulch grass, light brush, and woody vegetation up to 3 cm (1 inch) in diameter with reduced vibration and smoother operation.
  • Integrated mechanical FLOAT system allows the mulcher to follow uneven terrain, ensuring a consistent cutting height and cleaner finish on slopes and embankments.
  • Standard 3-belt V-drive transmission ensures reliable power transfer while protecting critical components from overload.
  • Features a universal mounting interface, allowing easy adaptation to most excavator brands; optional interface plates are available for specific OEM compatibility.
  • The adjustable 5" support roller improves ground contact stability, prolongs flail life, and lets operators fine-tune the cutting height in the field.
  • Front chain protection and rear rubber safety flap minimize debris ejection for increased safety during roadside or public space maintenance.
  • Lightweight design at 181 kg (400 lbs) reduces overall stress on the excavator arm, extending the life of your equipment while improving fuel efficiency.
  • Customizable with gear or variable displacement hydraulic motors, giving you control over flow compatibility, pressure tolerance, and performance tuning.
  • Optional Y blades or Y blades on shackles available for operators seeking alternative cutting profiles for varied vegetation types.
  • Ideal for municipalities, landscapers, contractors, and farmers maintaining canal banks, fencelines, rights-of-way, and overgrown lots.
  • Built by SEPPI M., a global leader in vegetation control technology, ensuring world-class engineering, serviceability, and long-term reliability.
