Features

Application

Designed for cutting narrow, straight trenches in the soil prior to laying electrical, telephone and cable lines, or water and gas pipe.

Direct Drive System

Direct drive system features a variable speed, bi-directional, gerotor style motor that delivers optimal chain speed, chain pull and torque for maximum trenching performance in a broad range of soil types.

Durable Anti-Back Flex Chain

Durable, double standard anti-back flex chain eliminates chain backlash and ensures teeth are positioned at the most efficient angle for smooth cutting and longer tooth life.

Hard-faced, Tungsten Carbide Steel Cupped Teeth

Hard-faced, tungsten carbide steel cupped teeth deliver long life in many soil conditions. Teeth are spaced for optimum digging performance in most soil types.

Hydraulic or Manual Side Shift

Hydraulic or manual side shift provides close trenching flexibility near structures or obstructions. Hydraulic side shift, standard on the T315 (optional on T109 and T112) is controlled from operator’s compartment using the standard flow auxiliary hydraulic circuit selector control.

Optional Chain Types and Cutting Widths

Optional chain types and cutting widths are available for specific soil, digging requirements and trench widths. These chain types include Standard, Combo, Terminator, and Rockfrost.

Large Diameter Bolt-On Spoil Auger

Large diameter bolt-on spoil auger improves loose soil removal from trenching area and allows for quick, easy removal and servicing.

Optional Bolt-On Crumber Bar
