A cutting device is configured to attach to a boom arm and includes a saw assembly with a cutting portion configured to cut into a target surface. The cutting device also includes a motor assembly coupled to the saw assembly. The motor assembly has at least two motors configured to rotate the saw assembly about two different axes. The cutting device further comprises a control system operatively coupled to the motor assembly. The control system has at least two sensors coupled to the saw assembly and the control system is configured to position the saw assembly to cut a target surface based on feedback from the at least sensors.

A self-propelled electric concrete saw having at least two electric motors. A first electric motor of the concrete saw is powered by an external power supply and can power both a saw blade and a drive system. A second electric motor of the concrete saw is powered by a rechargeable battery and can power the drive system. The concrete saw can be maneuvered by using the second electric motor with or without the concrete saw being connected to the external power supply.

An apparatus, such as for tree trimming, includes a mobile carriage having a frame and a pedestal supported by the frame. The apparatus further includes a boom, such as a telescoping boom that is secured to the pedestal through a boom support. The pedestal is pivotable with respect to the carriage frame so that the boom may be selectively operated in a variety of orientations. The mobile carriage of the apparatus is sufficiently compact to fit though tight openings, while also being capable of stably supporting boom extension for operation of a distal end of the boom at elevated heights.
