In an apparatus for controlling operation of a utility vehicle that detects a magnetic field generated by electric current flowing through a boundary wire of a working area and is driven to run within the working area based on the detected magnetic field, having left and right magnetic sensor installed at lateral right and left positions of the vehicle to produce outputs proportional to strength of the magnetic field, turning mode is switched between gentle turning mode to make the vehicle turn while running near the boundary wire and sharp turning mode to make the vehicle pause near the boundary wire and then turn, when it is determined from the outputs of the magnetic sensors that the vehicle approaches the boundary wire, each time predetermined conditions are satisfied, and operation of the prime mover is controlled such that the vehicle turns in accordance with the switched turning mode.

A power tool system has a power tool including an electrical device, a power device for powering the electrical device, a position or target detection system for detecting a position of the power tool and/or the power device, a source-based transceiver for at least transmitting data corresponding to the position detected by the position detection system, and a data retrieval and/or process equipment for selectively receiving data from the source-based transceiver at a position around the power tool and/or a position remotely removed away from the power tool.

A drive arrangement for a harvesting header of a harvesting machine having a running gear on which a feeder housing is mounted. A front side of the feeder housing has a header mount that moves relative to the feeder housing and on which the harvesting header is detachably fastened. An automated coupling mechanism is provided to link a driven shaft from the harvesting machine to a drive shaft of the harvesting header as the header is connected to the harvesting machine. The drive connector connected with the header mount is movable relative thereto during the attachment of the harvesting header to axially align the driven shaft and drive shaft as the harvesting header approaches the feeder housing during the attachment to accommodate differing header drive shaft orientations.

A zero turn radius mower including a pair of rear drive wheels, a mowing deck including multiple cutting blades, an electric storage battery, a pair of electric wheel motors each operable to rotate one of the rear drive wheels, multiple electric blade motors each operable to rotate one of the multiple cutting blades, and a master controller in communication with each of the pair of wheel motors and the multiple blade motors. The master controller is operable to control a rotational speed of each of the pair of wheel motors and the multiple blade motors. The master controller is operable to stop rotation of the cutting blades when the wheel motors are operating below a threshold speed.

A drive and control system for a lawn tractor includes a CAN-Bus network, a plurality of controllers, a pair of electric transaxles controlled by the plurality of controllers, and one or more steering and drive input devices coupled to respective sensor(s) for sensing user steering and drive inputs. The plurality of controllers communicate with one or more vehicle sensors via the CAN-Bus network. The plurality of controllers receive the user's steering and drive inputs and posts on the CAN-Bus network and generate drive signals to obtain the desired speed and direction of motion of the lawn tractor.
