Picking a skid steer trencher means matching the attachment to your machine, the trench dimensions your jobs call for, and the ground you dig in most. Go too big and your skid steer will struggle and feel unstable; go too small and you'll be making extra passes on larger projects. Here's what to look at before you decide.
Assess Your Machine First
Start with your skid steer's operating weight, rated operating capacity, and auxiliary hydraulic flow. Mini machines usually need lighter attachments with MP600 mounts. Compact and mid-frame loaders can step up to MP910 or MP1220 universal quick-attach mounts for bigger trenchers. The attachment weight plus the forces from digging have to stay within your machine's rated operating capacity. Overloading will wear things out faster and hurt stability. A skid steer trencher that's too heavy for your machine is a safety issue as much as a performance one.
Evaluate Hydraulic Flow Requirements
Auxiliary hydraulic flow dictates trencher chain speed and how well it cuts. Standard-flow machines typically work with lighter trenchers, while high-flow machines are needed for larger boom setups and tougher digging. Not enough flow and the chain turns too slowly, cutting productivity especially in hard ground. Too much flow can overspeed the chain, wearing teeth faster and risking damage to the motor. Knowing the difference between high-flow vs low-flow skid steer trenchers is a must before you pick a model.
Determine Trench Depth and Width
The maximum depth you need dictates boom length. TGEC trenchers come in configurations with cutting depths from 500 mm up to 1220 mm depending on boom size. The 36 in boom models reach 960 mm, while the 48 in TG-TCR1220 goes to 1220 mm. All models share a standard 150 mm cutting width, which handles most utility conduit, irrigation tubing, and drainage pipe.

Match Tooth Configuration to Soil Conditions
The soil you dig most often should drive your tooth choice. Standard carbide-tipped teeth handle loam, clay, and sandy soil just fine. Harder or rockier ground may call for rock teeth or a heavier-duty chain setup. Think about whether you're dealing with compacted fill, rocky subsoil, or mostly loose topsoil. Wrong or worn teeth slow cutting speed and increase hydraulic load. For general utility and irrigation work, standard carbide teeth are usually all you need.
Consider Mounting Interface and Compatibility
TGEC trenchers come with MP600, MP910, or MP1220 quick-attach mounts to fit different machine sizes. MP600 works with mini skid steers, MP910 with compact machines, and MP1220 is the universal standard for mid-frame and larger loaders. Double-check that your machine's quick-attach type matches the trencher mount before you order. Custom mounting plates are available for non-standard interfaces or specific brands.
Evaluate Total Cost of Ownership
Look beyond the purchase price—factor in the cost of replacement teeth, chain sections, and other wear parts. A trencher with affordable, easy-to-find consumables will cost less to run over time. Also think about maintenance time: models with simple tooth replacement and easy chain tension adjustments mean less downtime. For rental fleets or high-use contractors, durability and parts availability often matter more than the lowest upfront price.
Final Selection Checklist
Before you commit, run through this list: attachment weight within your machine's rated operating capacity, hydraulic flow matching your auxiliary circuit, maximum digging depth covering your typical jobs, cutting width fitting the pipe or cable you install most, tooth configuration suiting your soil conditions, and mounting interface compatible with your quick-attach. Taking the time to check each one means you'll get a trencher that performs without overloading your machine.
