    Abstract: A cable puller has a frame, a capstan rotatably mounted on the frame, a motor which drives the capstan to rotate, a power supply which supplies electrical current to the motor, a transmission which transfers torque from the motor to the capstan, a display mounted to the frame, a sensor operable to generate a signal, and a controller. The transmission can operate in a low-speed configuration and a high-speed configuration. The controller is electrically coupled to the motor, the power supply, and the display. The controller includes computer executable instructions stored in a computer readable medium for controlling operation of the cable puller to receive the signal from the sensor, determine a torque of the capstan based on the signal, determine a tension of a cable being pulled based on the torque of the capstan, and generate a control signal when the tension of the cable approaches a predetermined tension.

    Abstract: A power trowel that includes a handle, a housing, a blade assembly including a trowel blade, a motor coupled to the blade assembly, a plurality of sensors configured to generate output signals related to an operational state of the power trowel, and a controller connected to the motor and the plurality of sensors. The controller is configured to receive the output signals from the plurality of sensors, determine, based on the output signals, a speed setting for the blade assembly and a pitch angle for the trowel blade, and control the motor to drive the blade assembly at the speed setting with the trowel blade at the pitch angle.
