Recommended Uses of Spider 820 PLUS

The Spider 820 PLUS is designed as a high-reach professional boom mower for demanding vegetation and infrastructure maintenance tasks where long working range, stability, and precise control are essential. It is especially suitable for:

  • Roadside and verge mowing for municipalities and road maintenance authorities
  • Hedge cutting and shaping along highways, main roads, parks, and public spaces
  • Tree and branch trimming along traffic routes, public areas, and infrastructure corridors
  • Maintenance of ditches, embankments, canals, and steep or hard-to-reach slopes
  • Large-scale green area and park maintenance for professional landscaping contractors
  • Agricultural boundary and access-road maintenance, including field edges and farm infrastructure
  • Forestry and utility corridor maintenance, such as vegetation control along forest roads and service lines

Thanks to its long horizontal and vertical reach, reversible left- and right-side working positions, and highly flexible cutting-head movement, the Spider 820 PLUS is particularly well suited for wide, complex, and heavy-duty working environments where safe working distance, high productivity, and excellent operator visibility are required.
