How the Automatic Wheel Drive Works:
This new 712 Micro Trencher features an all new wheel drive propulsion system. The Barreto-matic uses a load sensing hydraulic valve to adjust the trenching wheel speed according 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. This keeps a constant load on the engine regardless of differing soil conditions or the depth of cut. It also eliminates the responsibility on the operator to constantly adjust wheel speed. Nothing could be easier for the novice operator.
