BARRETO | 712 Micro Trencher (712-MT)

Description

The 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 and the wheel drive speed will automatically increase. This keeps a constant load on the engine, regardless of the depth of cut or differing soil conditions. Not only does this help the trencher run at optimal efficiency, it reduces stress on the components, increasing their longevity.
