The company says its tracked trencher can tackle a broad range of jobs, including water, sewer, gas, power and underdrain installations and pipeline distribution.
The HT275 is powered by a 275-horsepower Cummins Tier 4 Final diesel engine – more than twice the horsepower of its second-largest trencher, the wheeled RT125, at 121 horsepower, according to the Equipment World Spec Guide. (Note: the new 2018-19 Spec Guide and Yearbook is scheduled to come out in October.) The HT275’s hydrostatic trencher-chain drive allows the operator to match chain speeds to soil conditions.
The company further increased productivity by making it easier and quicker to change attachments. The HT275 features four hydraulic quick-disconnect blocks that allow rear attachments to be changed without heavy lifting equipment. Attachments include a centerline attachment for installations of 4 to 10 feet and 14 to 26 inches wide, and an offsetting, sliding attachment for installations 3 to 6 feet deep and 8 to 24 inches wide, which has an optional truck-loading conveyor.
The company says the cab is the most spacious in its class size and has a second seat for training sessions.
Daily service and inspections, including slowly advancing the digging chain from ground level, can be conducted via wireless remote so the operator doesn’t have to leave the cab. And the one-piece hood fully opens to reveal the engine and all routine maintenance points. The patent-pending track frame can also be easily removed for maintenance.
The HT275 is 102 inches wide, which means it can be hauled on a standard-load trailer without a permit.
