Background and Identification
The Barreto model E718MTH-4S is an 18-inch hydraulic trencher produced by Baretto Manufacturing, Inc. This machine is designed for digging trenches in "normal" ground of reasonably soft dirt and stones up to 3" (15cm) in diameter. Ground that is extremely hard-packed, contains larger stones, high clay contact, or is in a very dry or frozen condition may be unsuitable for normal trenching with this machine. It utilizes a load sensing hydraulic valve to adjust the trenching wheel speed to the load on the digging chain.
The Barreto model E718MTH-4S includes a 1.5-gallon hydraulic reservoir. It can trench up to 18-inches deep at a speed of 148 feet per minute. It has a digging chain speed of 200 feet per minute and a ground drive reverse speed of 23 feet per minute. A load sensing valve on the machine automatically adjusts the wheel speed to the digging conditions. A manual lever lowers the boom and locks in one of three positions for trench depth.
The model GX200UT2 displaces 196 cubic centimeters (cc) and produces a net power output of 5.5-horsepower at a speed of 3600 revolutions per minute. The engine produces a net torque of 9.1 foot-pounds at a speed of 2,500 revolutions per minute. It can hold up to 0.83 gallons of gasoline and 0.63 quarts of engine oil. Honda recommends using unleaded 86 octane or higher fuel for this engine.
