side auger

Baumalight Trenchers are designed with a convenient side auger. The side auger keeps the dirt clear from the trenching action but still near the trench when it’s time for back filling.

crumb scraper bar

The Trencher has a crumb scraper bar as standard equipment, this helps to scrape and sweep extra dirt and debris into the chain where it is lifted out of the trench. The heavy construction and hinged design mean that the scraper performs no matter what depth of trench you are digging.

The sealed drive keeps the dirt out and the trencher going. The compact and strong planetary drive unit delivers the hydraulic power directly to the sprocket of the digging chain for good digging performance. There are no roller chains that jump or stretch. Maximum torque transfer. The motor is mounted directly in-line with the main sprocket.

Planetary Drive System

solid steel nose

The Baumalight Trencher’s heavy duty nose is precision machined from a piece of solid steel. It runs freely on dual tapered roller bearings to deal with the extreme forces of trenching.

Dirt is the enemy of all bearings. A precision machined washer protects the bearings from rocks and dirt. This initial barricade is reinforced by the rubber seal on the bearings, finishing the job is the easily accessible grease fitting which keeps the bearings lubricated and protected from moisture and keeps our nose running freely.

Solid steel nose

adjustable chain tension

Adjusting the chain tension with a couple of pumps. The grease cylinder tensioner allows you to adjust the tension of the chain quickly with only a grease gun. By applying grease to an internal cylinder the roller nose is pushed forward taking the slack out of the chain. What could be a long frustrating process is now a few quick pumps.
