Abstract: A land preparation tool includes a tool body, wherein the tool body comprises a cutting surface, a mounting surface disposed along a side of the body opposite the cutting surface, a first angled surface that sweeps backward from the cutting surface toward the mounting surface, and a second angled surface that is disposed on a side of the cutting surface opposite the first angled surface and sweeps backward from the cutting surface toward the mounting surface. The tool further includes a blade disposed on the same side of the tool body as the cutting surface and on an end of the tool body opposite the first and second angled surfaces and a channel disposed into the mounting surface and extending into the tool body. The mounting surface includes a nonplanar profile.

Abstract: Embodiments of a land preparation tool for preparing land includes a tool mounting surface defining a non-planar tool mounting surface profile and a cutting surface disposed on a surface opposite the tool mounting surface. A first channel for receiving a first securing bolt and a second channel for receiving a second securing bolt, both channels disposed within the land preparation tool and are adjacent and parallel to each other. An intermediate connector includes a first connector channel, a second connector channel, a tool interface, and a tool holder interface, the tool interface couples with the tool mounting surface of the land preparation tool. A land preparation apparatus includes a tool holder secured to a rotatable drum, and the land preparation tool and the intermediate connector are secured to the tool holder with the two securing bolts.

Abstract: Embodiments of a land preparation apparatus comprise a rotatable drum and a plurality of tool assemblies disposed on the rotatable drum, wherein each tool assembly comprises a tool holder comprising a mounting surface defining a non-planar profile, and a land preparation tool connected to the tool holder and comprising a mounting surface in flush contact with the tool holder mounting surface. The mounting surface of the land preparation tool defining a non-planar profile, which is the inverse of the non-planar profile of the tool holder mounting surface.

Abstract: Embodiments of the present apparatus comprise a land preparation apparatus that includes a rotatable drum, a plurality of tool holders arranged on the drum, wherein each tool holder comprises a first connection interface, a plurality of land preparation tools, wherein each land preparation tool is configured to connect with a tool holder and wherein each land preparation tool comprises a second connection interface, a plurality of removable connectors, wherein the connectors comprise a material different from that of the tool holders and the land preparation tools, wherein each connector is removable from the tool and the tool holder, and wherein each connector is configured to mate with a first connection interface of a tool holder and with a second connection interface of a land preparation tool. The apparatus further includes a land preparation vehicle comprising an attachment connection device configured to mate with the rotatable drum, wherein the vehicle is configured to drive the rotatable drum.

Abstract: Embodiments relate to braking high-speed rotational cutting equipment. In particular, some embodiments relate to forestry machinery having a cutting or mower apparatus, and further having a hydraulic brake. The brake includes a counterbalance valve which pressurizes fluid at the motor outlet to a predetermined level when flow of hydraulic fluid from a pump to a motor is discontinued. The hydraulic brake may include a restrictor orifice to reduce sudden pressure increases on the motor. The predetermined pressure level may be between about 2000 psi and about 4000 psi and the orifice may have a diameter of between about 0.025 and 0.040 inches. The counterbalance vent port can hydraulically connect to the motor case line. An anticavitation valve can be at the counterbalance valve port can supply fluid to the motor inlet after the flow from the pump discontinues. Additional embodiments include related hydraulic control systems and methods.
