Seppi S9 dyna

Heavy duty flail mulcher with side shift 100 – 180 HP

  • Flail mulcher with side shift to mulch grass and prunings up to 9 cm [3.5”] Ø

The new “S9 dyna” is reversible model with Linkage with strong hydraulic side shift on corrosion resistant tubes. Innovative, pyramid-shaped 3-point linkage with high stability is suitable for front and rear attachment.

The S9 series opens the heavier range of SEPPI M. flail mowers.

S9 casing made of high-tensile steel (S420), with internal replaceable wear plates, reinforced belt cover and strong, unique roller design using a double tapered roller bearing unit for a long life and the low maintenance costs. SEPPI S9 dyna machines mulch grass and vegetation up to 9 cm [3.5”] Ø. The rear hood allows adjustment of the degree of mulching.

Helical distributed and high resistent SEPPI SMO flails for universal use are for high cutting quality at uniformly distributed power. Double counterknives inside the S9 dyna casing will give a perfect result when mulching. Strong welded belt cover minimizes accidental damage. With the roller positioned close to the rotor, it is automatically cleaned by the rotating flails and the cut material is evenly distributed over the top of the roller. Adjustable large diameter roller positioned close to the rotor improves mulching on uneven ground and prevents scalping.

The SEPPI S9 dyna mulchers are suitable for the most varied uses: in agriculture for orchards, right-of-way management, creation of fire breaks, vegetation management, road side maintenance, land clearing and site prep…
