Barreto 712MTH micro-trencher Hydraulic Trencher 18 inch Pro Qaulity Tools

Used Hydraulic Trencher 18"

The Barreto 712MTH micro-trencher features a unique automatic wheel drive propulsion system.

This trencher utilizes a load-sensing hydraulic valve to adjust the trenching wheel speed to the load on the digging chain.

When the load on the digging chain increases, the sensing valve sends less oil to the wheel drive motor, and the wheel speed will automatically slow down.

When the load on the digging chain decreases, the sensing valve sends more oil to the wheel drive motor.

The wheel drive speed will automatically increase, keeping a constant load on the engine, regardless of the depth of the cut or differing soil conditions.

Not only does this help the trencher run optimally, but it also reduces stress on the components, increasing their longevity.


The automatic adjustment to the wheel speed eliminates the responsibility of the operator to adjust their wheel speed constantly.

Nothing could be easier for the novice user.

One control lever operates the wheel drive, and one handles the chain drive.

After engaging the chain drive lever, the operator engages the wheel drive lever and lets the trencher do the work.

When the wheel drive is forward, the chain drive will not activate, eliminating costly repairs sometimes caused by inexperienced operators.

Small trenchers can become one of your leading revenue sources.

With a unique design that provides the limited need for maintenance and repair, the 712MTH will keep going out into the field repeatedly without sitting in the shop waiting for repair.

This machine is for digging trenches in “normal” ground of reasonably soft dirt and stones up to 3″ in diameter. 

Extremely hard-packed soil contains larger stones, has high clay content, or is very dry or frozen and may be unsuitable for normal trenching.

Consider using a more extensive trencher, backhoe, or other heavy equipment for such conditions.
