712MT Micro Trencher

Barreto’s 712MT Micro Trencher features an all-new wheel-drive propulsion system, utilizing a load-sensing hydraulic valve that adjusts 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 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. Digs 12-18” deep.
