Reversible Digging Chain

The compact size of this 84-in.-long, 33-in.-wide Ditch Witch 1330 hydraulic trencher allows it to work in narrow, confined areas. The unit is equipped with a 13-gross hp Honda GX390 gasoline engine and can trench to depths of 36 in. with trench widths to 6 in. One of its main features is a reversible digging chain for dislodging rocks or spoils caught in the chain. Also, color-coded controls are located within easy reach from the operator's position.

Ergonomic Design

Two new guns--CobraMax, a gooseneck torch with an ergonomic design and the Python, an advanced gooseneck torch for new and experienced operators--offer superior feeding to virtually eliminate friction in the line for smooth feeding and minimized damage to the wire, the maker says. They are suitable for aluminum applications using soft wire. Each gun can handle both steel and aluminum wire from .030 to 1/16 in. The Python line consists of five new torches and offers several options, starting with the standard air-cooled Python torch rated 200 amps at 100% duty cycle.
