  • Patent number: 11968924
    Abstract: A cutting head body for an agricultural machine, such as a mower or a trimmer, is configured to receive a cutting line for cutting weeds, grass, or other materials. The cutting head body includes an inlet area having a cavity with a node location configured to receive a node of a cutting line, and an outlet area having a cavity configured to open to an exterior of the cutting head body. The cutting head body may include a first passageway connecting the inlet area to the outlet area and a second passageway connecting the inlet area to the outlet area. The cutting head body is rotatable about a rotational axis to move the cutting line. In some embodiments, the cutting head body is fixed to a rotatable shaft. In some embodiments, the cutting head body rotates about a fixed shaft.

  • Publication number: 20210185873
    Abstract: A driveline assembly for equipment, such as a tiller, includes a pair of counter-rotating bevel gears supported on a wheel shaft and rotatable relative to the wheel shaft. The driveline assembly includes a first slider gear movable between a first position in which the first slider gear is engaged with a first bevel gear of the pair of bevel gears, and a second position in which the first slider gear is engaged with a second bevel gear of the pair of bevel gears. When the first slider gear is engaged with the first bevel gear, the first bevel gear becomes operatively connected to a rotatable tine shaft to rotate tines in a first direction. When the first slider gear is engaged with the second bevel gear, the second bevel gear becomes operatively connected to the rotatable tine shaft to rotate the tines in a second direction opposite the first direction.

  • Publication number: 20180124990
    Abstract: A rotary tiller comprises a frame, a cylindrical drum rotatable relative to the frame, a plurality of tines extending from the cylindrical drum, a motor at least partially disposed within the cylindrical drum, wherein the motor is configured to rotate a motor output member, and a transmission at least partially disposed within the cylindrical drum and configured to engage the motor output member. The transmission is operable to drive rotational movement of the cylindrical drum.

  • Publication number: 20070024356
    Abstract: In the present technique for power management of a power amplifier, an amplifier bank from a plurality of amplifier banks in a power amplifier that has been switched off for a longest period of time is assessed (826) to provide a lowest amplifier bank. With this lowest amplifier bank, an up-threshold that is associated to the lowest amplifier bank is assessed (828), followed by another assessment (820) of a current power output of the power amplifier. It is next determined (830) whether the current power output corresponds at least in a predetermined way to the up-threshold, and if so, the lowest amplifier bank is accordingly switched on (832).

  • Publication number: 20070024357
    Abstract: In the present technique for power management of a power amplifier, it is first determined (314) whether a counter value corresponds at least in a predetermined way to a counter threshold, and if so, a current status of at least one amplifier bank from a plurality of amplifier banks in a power amplifier is switched (316).

  • Patent number: 5383202
    Abstract: A method is provided of attenuating a signal value within erroneous frames of a logarithmically coded digital signal. The method includes the steps of detecting an erroneous frame of the logarithmically coded digital signal and adding an attenuation value to a frame exponent of the erroneous frame.
