摘要： An apparatus for weed removal includes a chassis and at least two end effectors mechanically coupled to the chassis, each end effectors including a rotary axle, each rotary axle coupled to a drive unit for receiving a mechanical force to cause the rotary axle to rotate. The rotary axles, along with weed abrasion members coupled thereto, are at least partially covered by a deflector. A front end effector is configured to dislodge a crown and/or stem portion of unwanted plant material from the ground, while another end effector is configured to convert the unwanted plant material that has been dislodged from the ground into mulch.

摘要： A reaping machine includes a sickle bar that can rotate and at least one reaping blade arranged on the sickle bar. The reaping blade is supported so that it can pivot on a pin fastened to the sickle bar. The pin has a fastening section for fastening to the sickle bar and a holding section separated by a shoulder from the fastening section for holding the reaping blade so that it can pivot. To simplify the placement or installation of the pin on the sickle bar, at least one raised section extending in the radial direction past a circumferential segment of the pin is formed in the fastening section of the pin.

摘要： The mower blade with replaceable inserts includes a blade bar having diametrically opposite reliefs therein for replaceable cutting inserts. Headed pins extend from each relief, and each insert has corresponding slots. The slots have larger diameter outer ends to clear the larger diameter heads of the pins, the inner portions of the slots being stepped to fit closely about the narrower shanks of the pins. The inserts drop into position over the corresponding pins, and slide outwardly to be retained by the heads of the pins. The outer (lower) surfaces of the heads of the pins are coplanar with the outer (lower) surfaces of the inserts when installed. The cutting edge portions of the inserts extend over and are in direct contact with the corresponding leading edge portions of the blade bar, thus protecting the bar and transferring impact forces directly to the bar rather than through the pins.
