A method determines a presence of a motor-driven tool inside a tool position region and/or a tool position of the tool. A transmitter is mechanically connected to the tool, wherein the transmitter wirelessly transmits a signal. The transmitted signal is attenuated by the tool and has an item of transmitter information for taking the attenuation into account. The method has the steps of: capturing a respective reception signal strength value of the transmitted signal at receivers, wherein the receivers are arranged at different receiver positions; and determining the presence of the tool inside the tool position region and/or the tool position of the tool on the basis of the captured reception signal strength values and the received transmitter information for taking the attenuation into account.

An air leaf stripping system and an agricultural machine equipped with such system. The system is used in viticulture for stripping leaves from vinestocks. The system can be mounted on a tractor and includes adjustment means consisting of a rotary joint and means for rotating a housing and includes an arm that has a main longitudinal axis and includes the supply line and an attachment part intended to be mounted on the agricultural machine directly or via a frame. The supply line-is guided along the attachment part and connected to the leaf stripping means through a junction in the housing via the rotary joint. The rotating means being arranged so that the housing can be rotated about a first axis passing through the junction and substantially perpendicular to the main longitudinal axis of the arm, between at least two separate angular positions relative to the first axis.

Disclosed herein is a power tool that includes a direct current power source, motor, and motor controller. In some embodiments, the power source comprises a battery pack configured to supply current at a nominal voltage in excess of 100 VDC. Embodiments of the tool are configured to operate at a high power at least comparable to tools operating at lower voltages, and to produce noise levels in operation that are less than 65 decibels.

A small internal combustion engine includes a housing and an internal combustion engine body arranged in the housing. The internal combustion engine body includes a cylinder, a crankcase, a piston arranged in the cylinder, a crankshaft arranged in the crankcase and driving the piston, and an oil pan arranged at a bottom of the crankcase. The oil pan has an oil pan inlet, and the housing has a housing oil inlet. A hose connected to the oil pan inlet and the housing oil inlet forms a fluid passage for lubricating oil to flow from the housing oil inlet to the oil pan. A related garden tool includes a power source assembly that drives a working assembly to operate via a power transmission assembly.

A working apparatus has a manual operating region, a tubular part extending away from the manual operating region, and an electric cable arrangement in the tubular part. The working apparatus includes a rod-shaped cable holder, which is inserted into and held in the tubular part and has a cable holding arrangement, by which the cable arrangement is held in a pre-mounted manner on the cable holder. An assembly method secures the cable arrangement on the cable holder by the cable holding arrangement, and inserts the cable holder, with the cable arrangement held thereon, into the tubular part. The working apparatus may be a battery-operated, hand-guided garden or forestry working apparatus.

The present utility model provides a reciprocating saw clamping device, the clamping device being mounted on a machine body of the reciprocating saw, close to a cutting saw blade located at a front end of the machine body of the reciprocating saw, and being configured to clamp an object to be cut when the reciprocating saw is performing a cutting operation, wherein the clamping device comprises a clamp and a clamp support, the clamp and clamp support being rotatably hinge-connected, and the clamping device is removably mounted on the machine body of the reciprocating saw by means of positioning structures which fit each other and are arranged on the clamp support and a housing of the reciprocating saw. The present utility model also provides a reciprocating saw having the clamping device. The reciprocating saw clamping device of the present utility model is not only structurally simple and convenient to operate, but can also satisfy cutting requirements of different sizes, with a larger range of operations.

The present invention provides an electric pruner saw, comprising a motor (12), a wobble bearing (13) and a saw (14, 15), and further comprising a balancing component; the balancing component and saw vibrate at the same frequency in parallel directions, but the phases of vibration of the balancing component and saw differ by 180°, such that the opposite-phase vibration of the balancing component partially or completely offsets the vibration of the saw. Furthermore, the wobble bearing in the pruner saw is arranged at an upper side of the motor, such that a rotating rod of the pruner saw is located between the motor and a saw rod; thus, the wobble bearing is closer to the saw rod, so the length of a swing rod of the wobble bearing is shortened, and consequently the various components are arranged more compactly, thus reducing the volume of the pruner saw.

The present invention provides an improved, autonomous unmanned aircraft vehicle (UAV) for harvesting or diluting fruit, and a control unit for coordinating flight and/or harvesting missions thereof, as well as a system and method for harvesting fruits.

The present invention provides a fruit harvesting, dilution and/or pruning system comprising: (a) a computerized system for mapping an orchard or a map of trees position and their contour in a plantation; (b) a management system for autonomous unmanned aircraft vehicle (UAV) fleet management for harvesting, diluting or pruning fruits; and a method for UAV autonomous harvesting, dilution and/or pruning of an orchard.

A vine or cane pruning apparatus, comprising a toothed wheel for guiding the pruning apparatus over vegetation in use, the wheel comprising a multiplicity of generally radially projecting teeth distributed about the periphery of the wheel for catching vegetation between gaps of the teeth, and wherein the wheel rotates by consequence of its engagement with the vegetation and vine or cane posts as the apparatus is driven along a row of vines or canes for pruning; and a driven rotary cutter mounted co-axially to the wheel for cutting vegetation caught between the teeth, the cutter being configured such that its effective cutting area falls within the diameter of the wheel.
