A ratchet mechanism (34) may be provided to maintain the chain tension upon reduction of the chain speed by preventing the sprocket (15) from moving toward the guide bar (2).

Abstract

For manually operated garden shears, it is proposed, in order to cut relatively thick material to be cut, to switch on an additional motor-driven closing force if necessary and to provide an electrical drive motor, which is preferably fed from a rechargeable battery, for this purpose. In order to keep the design of the drive motor and of the rechargeable battery small and to keep the available operating time of the rechargeable battery long, the motor-driven closing force is switched on only in case of need. In particular, the automatic determination of a case of need and the switching-on of the motor-driven closing force by means of an electronic control device in accordance with characteristic variables of the current cutting operation and test criteria stored in the control device are advantageous. In particular, switching-on of the motor-driven closing force can be restricted to cases in which the closing speed of the blade arrangement falls below a second, upper threshold value in the event of a manual force of the user exceeding a first threshold.

Advantageously, the pivot axis (SA) is inclined through an inclination angle between 3° and 20° with respect to the direction of the surface normal so that, in a first operating position, in which the handle (HG) partially overlaps the blade arrangement (MA) in projection onto the cutting plane (ME), the handle (HG) assumes a greater spacing from the cutting plane than in a second operating position, in which the handle (HG) is located on that side of the pivot axis (SA) that is remote from the blade arrangement (MA).

For a garden pump that is automatically switched off by means of a flow sensor that detects a minimum flow rate, a delay time between the time at which the flow rate falls below the minimum flow rate and the time at which the drive motor is switched off is set to at least 1.5 minutes, and after the drive motor has been switched off due to the flow rate falling below the minimum flow rate, the drive motor can be switched back on regardless of pressure by means of a control element to be operated by the user. Thus, the control device is made considerably simpler and cheaper compared to known embodiments that automatically switch back on when the pressure falls below a lower pressure threshold, and the loading of the electrical part of the pump is reduced and the service life of said electrical part is increased.

Abstract

To achieve a particular price point and/or to utilize a particular engine, riding lawn mowers may be configured with reduced size, weight, and/or power requirements, in order. A riding lawn mower may comprise a cutting deck coupled to a cutting blade, and an internal combustion engine having a displacement of less than 225 cubic centimeters. The internal combustion engine may be coupled to the cutting blade via a friction drive, wherein the friction drive is configured with a neutral bearing in order to reduce flat spotting of components of the friction drive.

Abstract

For a horticultural cutting device with a protective sheath (SH) capable of being attached detachably on a blade arrangement (MA), there is proposed an embodiment in which the protective sheath (SH) is securely retained in a positive-locking fashion and can be attached onto, and removed from, the blade arrangement (MA) in a simple manner. A particularly advantageous embodiment of a protective sheath (SH) as an injection-moulded plastic part is described.

Abstract

For a motor-driven garden device with a tool capable of being detachably connected to the housing of the device, in particular for grass shears with a grass shear cutting head and with a wheel arrangement detachably attached to the device for the grass shear operation, there is proposed to attach the wheel arrangement exclusively to a cover capable of being displaced relative to the housing and not to the housing of the device. Upon detaching the cover from the housing of the device, the wheel arrangement can stay on the cover.

Abstract

For a divisible lawn rake, a pivoting connection of the two sub-bodies about a tube as a pivot axis is described, wherein the two sub-bodies together with the sub-fans arranged thereon can be pivoted from a working position to a storage position without removing the sub-bodies from the tube. In addition, in an intermediate position of the pivoting motion, one of the sub-bodies can be removed from the tube, which forms the pivot axis and which is permanently fastened to the other sub-body, in order to handle the sub-bodies together with the respective sub-fans as separate tools. In the storage position, the tines of the sub-fans can advantageously mesh with each other at a distance from each other.

Abstract

For hand-operated garden shears, in particular tree-pruning shears, with a ratchet mechanism, it is proposed that, between a hand lever (H2) and a scissor lever (H1) between which a ratchet lever (RH) can engage in different latching positions according to the ratchet mechanism, there is also provided, in addition, a preferably rotatable abutment surface (AF) on the hand lever (H2) and a mating bearing surface (GF) on the lever extension, or vice versa, which, at the end of an initial closing operation with the ratchet lever (RH) in a first ratchet position, allow a continuation of the cutting operation as a direct cut without further use of the ratchet mechanism.

A typically battery-operated power tool, such as a chainsaw or hedge trimmer, comprising a working element (4), a motor (6) arranged to drive the working element (4) and a controller (9) arranged, to control the speed at which the motor drives the working element (4), in which there is provided a sensor (12) for at least one factor indicative of the efficiency with which the power tool is being operated, the controller (9) being arranged to vary the speed at which the motor (6) drives the working element (4) should the factor indicate that the power tool is being operated in a sub-optimal manner. Typically, the factor is the pressure which the user is applying the power tool, and the sensor (12) is a sensor for the current flowing through the motor (6).

Abstract

The invention relates to a garden pump arrangement comprising a centrifugal pump impeller. According to the invention, the rotational axis of the impeller is aligned vertically, the impeller chamber is positioned lower than the outlet connection and the inlet connection in the pump housing, and water is fed from below into the impeller chamber. Advantageously, the inlet connection likewise lies higher than the impeller chamber. The impeller chamber is thereby always sufficiently filled with water even when air bubbles occur in the delivered water and/or when the pump is not completely filled so that a low pressure that is sufficient for the suction can be reliably generated.

Abstract

For in particular motor-driven grass shears having blades that typically have a plurality of cutting fingers (FO, FU), protective structures (SO, SU) that protrude from the cutting fingers (FO, FU) of the blades perpendicularly to the cutting plane are provided on the cutting fingers in order to avoid serious injuries to fingers of a user that accidentally enter the cutting gaps (LU). For a moved blade, the protective structures (SO, SU) are moved together with the blade.

Abstract

A cutting blade (100, 200, 300) for a cutting apparatus and a method for manufacturing the cutting blade (100, 200, 300) are disclosed. Embossments (110) are provided on a sliding portion (104) of the cutting blade (100, 200, 300). The embossments (110) are suitably arranged on the surface (102) of the cutting blade (100, 200, 300). The embossments (110) on the sliding portion (104) of cutting blade (100, 200, 300) reduce a contact area between cutting blades. With reduced area of contact, the friction between reciprocating cutting blades is reduced. The cutting apparatus suffers reduced wear and tear due to less friction between cutting blades.
