Key Features and Options

  • Heavy-duty nose roller bearing lasts longer providing less “shock” to the trencher assembly and chain

Trencher Chains

• Cup and combo chains come standard with 2-pitch, anti-back flex design preventing chain links from “flexing” back in tough soil conditions.
• 4″ and 6″ chain widths available in soil/cup, combo cup/rock, welded rock, and bullet style rock tooth configurations. Lengths for 24″ and 36″ booms (48″ boom chains available in soil/cup and combo cup/rock only).
• Chain widening kits available for soil/cup chains to increase width to 8″ or 12″ widths.

Trencher Crumber

The Toro crumber is designed specifically to make the trench bottom clean and smooth. The crumber follows behind the chain to clean all “crumbs” from the bottom of the trench. The hardend tip of the crumber pulls any loose material back into the chain teeth.

Optional Auger

Recommeded for 8″ and 12″ chain kits and when using 48″ boom – longer auger helps full more dirt away from trench.
