The 5.8-metric-ton TB257FR also has a 7.5-inch tail-swing overhang that when combined with the STS boom enables 360-degree rotation nearly within the machine’s footprint. Takeuchi says that makes the compact excavator a key addition to jobs such as road and bridge work, city streets and working in between buildings where crews face tight space restrictions. The STS boom also keeps the counterweight in line with the center of the excavator for added stability.

The pressurized cab gets automotive styling with heating and air conditioning, defrost, windshield wiper and washer, skylight with sunshade and AM/FM/MP3 Bluetooth radio. Operators also get a high-back suspension seat, multifunction joystick controls, hand-dial electronic throttle control, adjustable armrest, cupholder and 12-volt power socket. The floor mat is removable and washable.

The excavator has three working modes of Standard, ECO and High Altitude. Engine features include automatic idle, automatic cold start and an engine safe start system.

The standard rubber tracks are 15.7 inches wide, with steel tracks as an available option.

Other features include LED working lights, travel alarm and multiple attachment presets. The excavator has an integrated hydraulic quick coupler control system.
