  • Publication number: 20260000014
    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: 20250063967
    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.
