Abstract: A tool head for a hand-guided implement possesses two rotatably mounted tools, wherein a first tool is drivable via a first linkage and a second tool is drivable via a second linkage. The tools are drivable so that they rotate back and forth in opposite directions about a common rotational axis. The first linkage possesses a first drive member coupled to a first coupling member pivotably about a first link axis. The first coupling member is coupled to the first tool pivotably about a second link axis. The second linkage possesses a second drive member coupled to a second coupling member pivotably about a third link axis. The second coupling member is coupled to the second tool pivotably about a fourth link axis. The rotational axis of the tools and the coupling drive axis span a center plane, which runs between the second link axis and the fourth link axis.

Abstract: A limb and branch trimming apparatus includes a frame having a support platform and an upstanding mast member; a cutting assembly having a plurality of cutting members, wherein the cutting members are rotatably connected at the mast member; and a power source for powering the cutting members independently from the vehicle's power source. The support platform of the limb and branch trimming apparatus is removably mountable to or near the top front portion of a vehicle. The apparatus is used for vertically cutting limbs, branches, and brush along a walkway, pathway, or trail where a tractor would typically be too large to navigate said pathway or trail.

Abstract: An edger has a main frame that can be advanced controllably relative to subjacent terrain and a cutting assembly on the main frame. A drive rotates the cutting assembly around a first axis. The cutting assembly is configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation. The cutting assembly has a perimeter edge with a contour extending over an axial distance. A shielding assembly defines a radially inwardly facing surface that resides radially outside of the perimeter edge of the cutting assembly. The radially inwardly facing surface has a shape that is at least nominally matched to the contour of an axial extent of the perimeter edge of the cutting assembly so that as the cutting assembly rotates the radially inwardly facing surface and perimeter edge of the cutting assembly cooperate to each avoid buildup of foreign matter on the other.

Abstract: An implement (1) comprises a number of work devices (2A,2B,2C) for performing work therewith in an operative position. The work devices comprise an input drive shaft (4) which sets the work devices into operation. At least one work device (2B) of the work devices comprises an output shaft (3B) coupled to the input drive shaft (4A) of the work device and the input drive shaft (4C) of a subsequent work device (2C). The mutual coupling of the input and output shafts of the work devices together forms an efficient single drive line with which the work devices can be driven simultaneously without a separate drive branch being required per work device.

Abstract: A control system and method for adjusting a rotational speed of a header on an agricultural vehicle based on ground speed of the agricultural vehicle. The header may include a plurality of cutters rotatably actuated with a header actuator. The control system may have a processor that compares a ground speed of the agricultural vehicle with a threshold ground speed. If the ground speed of the agricultural vehicle is below the threshold ground speed, the processor may command the header actuator to rotate the cutters at a constant predetermined rotational speed. If the ground speed of the agricultural vehicle is above the threshold ground speed, the processor may command the header actuator to increase rotational speed of the cutters in proportion to the ground speed of the agricultural vehicle.
