100, 150 or 200 mm chain widths.
Earth chain for soft ground and clay, combo for hard soil, roots and soft shale, or Diggatac tungsten carbide for rocky ground and asphalt.
An adjustable skid foot holds the dig depth steady for an even trench, and you can see it from the cab.
The Headstart crumber lets you start trenching with the crumber already in the ground.

Warranty is 3 years on the gearbox, which is made in-house in Australia, and 2 years on the motor. Tell us your machine make and model and your coupler type (flush-face or ISO) when you order, and we'll check it fits before anything is ordered.
