Milling instead of Excavating

The perfect machine as an attachment for tractors is many times faster than any excavator. The milling wheel is equipped with carbide round shank picks, which do not stop even at stones in the ground. Even in winter, with soil frozen 60 cm deep, operation is possible without problems.

More economical and powerful than a self-propelled trencher: Optional - empty conduits are laid directly in one pass and immediately covered with fine material!

  • Maximum Power Transmission: Direct drive via the PTO shaft ensures enormously high torque.
  • Robust Technology: Less wear than with a conventional milling chain.
  • Proven System: The round shank picks use the same reliable system as an asphalt milling machine.
  • Attachment Trencher: Designed as a powerful milling wheel specifically for tractors.
Optional: Cable laying device (DL) for simultaneous direct laying of empty conduits or cables including route warning tape.

Milling instead of Excavating

Stehr attachment trenchers represent a new drive concept that transmits enormously high torque to the milling tooth with relatively low drive power. Since the well-known similar trenching wheels, almost all of which come from America, are designed as self-propelled machines with the same drive concept, where the milling wheel is always driven from the center via the gearbox, only relatively shallow cutting depths can be achieved.

With the SGF 1300, you achieve exact trench walls and up to 10 times higher performance compared to an excavator.
