The HT275 heavy-duty trencher from Ditch Witch has a Cummins 275 hp T4 engine and a hydrostatic trencher-chain drive with a variable displacement motor, allowing operators to match chain speeds to soil conditions. The trencher can do installations up to 10 feet deep and 26 inches wide, and it has four hydraulic quick-disconnect blocks that reduce the time it takes to change attachments. The suspension mounts to the center of each track frame, providing the ability to float each track independently, taking stress off the main frame. 800-654-6481; www.ditchwitch.com
