No matter what your trenching task is, Baumalighnt’s TN548 is up for the job. Quickly and safely bury valuable cables and utility lines underground and out of harm’s way. The TN548 Trencher will easily cut trenches up to 48” deep and between 6” to 10” wide, depending on the chain option. The TN548 is powered by a powerful planetary drive system. With no roller chain to worry about, the planetary drive unit delivers hydraulic power directly to the sprocket of the digging chain for optimal trenching performance.
For even more versatility, the TN548 Trencher can be mounted to a skidsteers between 3000 and 7000 lbs. or use this Trencher on your tractor using the optional 3-point hitch mount.

This Baumalight Trencher can also be mounted to a tractor. The optional 3-point hitch tractor mount has a cylinder that provides angle and depth control. To use this 3PH adapter, your tractor must have a hydro-static drive. Two hydraulic remotes are required, kits are available for tractors with only one set of external hydraulic connections.
Part number D001393 - 3 Point Hitch Trench AXE Adaptor (bolt on - does not include S1050).
This optional external control kit is mounted on an adjustable arm. The control is great for smaller tractors with limited HP and for tractors with only one hydraulic remote.
Part number S1050 - Valve kit for tractors with one remote (add $550 if shipping for field install).
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.
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.
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.
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.
