Text version of the page

• 250 hp powertrain • Compact size • Rugged construction The 765HD’s mechanical power train with torque converter provides power to the chain as digging conditions dictate. Multiple chain speeds deliver full horsepower in varying conditions. The head shaft chain drives are fully enclosed and run in an oil bath for much longer life. The unibody tractor frame weldment is stronger than bolted plate designs and can be equipped with a variety of chain widths and cutting depths. The 765HD has a computer controlled transmission to reduce or prevent shock loading on components such as the digging chain. Its undercarriage tilts a total of 17° to keep the digging chain vertical while the machine is working on a slope. 765HD Mechanical Drive Chain Trencher • Mechanical drive provides stronger components, increased power The mechanical chain drive has proven to be much more rugged and trouble free than hydrostatic designs Powerful Cummins® Diesel engine Right angle drive Powershift Transmission Inner chain case Outer chain case Headshaft sprocket Torque converter
