Compost turner for triangular windrows

The Topturn is one of the most widely used compost turners in the world. With the new X55 we are further extending our position. Inspired by our customers, this third generation of the Topturn offers top performance with complete comfort and convenience.

The 242 kW engine meets the latest emissions standards (Tier 4f/EU Stage IV), and the new cooling system keeps everything cool even under heavy loads and high outside temperatures. Further plus points are the larger, comfortable cabin and new automatic drive for relaxed working, and the hydraulically extendible maintenance platforms for fast and easy maintenance.

Wheel drive or Track drive

  • Highlights

    Just drive

    Wheel or tracks? - this is not a philosophical question at Komptech, but rather a decision made by our customers. The wheeled chassis provides a high level of traction, quick maneuverability and best driving comfort. The tracked chassis offers optimal traction on difficult terrain.

  • Highlights

    Perfect turning

    A large dimensioned and powerful hydraulically driven drum with effective conveyor and throwing tools acccelerates the turning and rotting processes. This ensures all materials are mixed before passing through the drum so nothing is missed. Also available for operations with high mixing requirements is a specially designed mixing drum.

  • Highlights

    Lift-off to work

    Entry into the cab is through a front panel door. Two lift arms then swivel the cab from the entry position on the ground into the working position directly above the tunnel. When the cab is in the transport position the turner is very compact, simplifying multi-site use.

  • Highlights

    On top of the situation

    Work made easier - the new cabin is a comfortable workspace, with more room, powerful air conditioner and air-cushioned seat. The new information system can be intuitively operated using a large colour display.

  • Highlights

    Maintenance made easy

    A press of a button turns the left and right body panels into roomy maintenance platforms with convenient access steps so the operator can reach all maintenance points safely and easily.

  • Highlights

    Right options

    By a lateral displacement device coupled to the turner transportation distances are minimised, visibility and monitoring are improved. By collapsing two windrows the rot shrinkage is smoothed out, making full use of the space. Further options: Watering by a hose system, a scraper device for getting the lowermost ground layer and a fast version for quick maneuvering.
