TNM336B for Bobcat mini skidsteer

The TNM336B Trencher is the ideal solution for cutting trenches in tight spaces, specially designed to be compatible with Bobcat mini skid-steers. This trencher provides the same aggressive performance as the TN236 but is specifically tailored to seamlessly work with Bobcat mini skid-steer loaders, which typically weigh between 1500 - 4000 lbs, enabling easy maneuverability in compact areas.

With the TNM336B Trencher, you can confidently cut trenches up to 36" deep and between 4" to 6" wide, depending on the chosen chain option. Equipped with a hydraulic drive system, this trencher ensures efficient and powerful trenching performance.

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.

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.

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.
