Baumalight Trencher | Model TNM-336B | Trencher Depth 36" | Width 4" - 6" | Hydraulic Flow Range 7-18 GPM | For Skid Steers
DESCRIPTION
The Baumalight TNM336B Trencher is the perfect solution for precise trenching in confined areas, delivering rugged performance in a compact footprint. Specially engineered for Bobcat mini skid steers, this powerful trencher makes light work of cutting clean, consistent trenches up to 36 inches deep and 4" to 6" wide all while maintaining exceptional maneuverability in tight spaces.
Designed with the same performance DNA as the TN236, the TNM336B pairs effortlessly with Bobcat loaders weighing 1,500–4,000 lbs, offering a hydraulic flow range of 7 to 18 GPM and accommodating machines with 10–25 HP. Whether you're laying irrigation lines, electrical conduit, or plumbing, the TNM336B gets the job done with speed, efficiency, and unmatched precision.
Built tough with thoughtful engineering, it includes features like a crumb scraper bar, solid steel nose, and side auger to keep your trenches clean and ready for backfill. Its grease cylinder tensioner makes chain adjustments a breeze, turning a potentially frustrating task into a few quick pumps.
Whether you're a contractor, landscaper, or utility installer, the TNM336B offers a seamless blend of power, durability, and compact design making it a must-have for any Bobcat mini skid steer operator.
Key Features

- Up to 36" Trench Depth: Allows for substantial trenching depth for various applications.
- Adjustable 4" to 6" Trench Width: Provides flexibility to suit different project requirements (dependent on chain option).
- Efficient Hydraulic Drive System: Ensures consistent and powerful trenching performance.
- Convenient Side Auger: Clears loose soil from the trench while keeping it nearby for backfilling.
- Standard Crumb Scraper Bar: Helps to create a clean trench by removing excess dirt and debris.
- Robust Solid Steel Nose: Precision machined and runs on durable dual tapered roller bearings for smooth operation and longevity.
- Adjustable Chain Tension: Allows for quick and easy chain adjustments using a standard grease gun.
- Optional Bobcat Cheater Adapter Plate (D006290): Enables the use of standard mini skid steer attachments on your Bobcat mini skid steer.

- Optional Chain and Tooth Styles Available: Including 4" and 6" widths and bullet-style teeth for rocky soil.
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. | ![]() |
PLANETARY DRIVE SYSTEM |
The sealed drive keeps the dirt out and the trencher going. The compact and stron g 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. | ![]() |
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. | ![]() |
