摘要： A flexible mower deck includes a center deck with a plurality of belt driven pulleys for rotating a plurality of rotary cutting blades under the center deck. A wing deck is pivotably attached to each of the first and second ends. A motor on each wing deck rotates a rotary cutting blade by actuating a switch in an operator station to pivot each wing deck to a mowing position.

摘要： Described are lawn mowers/autosensing modules for lawn mowers configured to engage and/or disengage a drive motor based on one or more of: a tilt angle relative to a direction of travel, rotations of at least one wheel, applied load, a tension and a lawn mower position. The lawn mowers may comprise: a cutting blade(s); a blade motor operatively connected to the cutting blade(s); a drive motor operatively connected to a wheel assembly; a tilt sensor configured to sense a tilt angle of the lawn mower; and a controller operatively connected to the drive motor and in communication with the tilt sensor, and configured to disengage the drive motor in response to receiving a disengage signal, without disengaging the blade motor. When the tilt sensor senses the tilt angle is at or above a disengage angle, the tilt sensor transmits the disengage signal for receipt by the controller.

摘要： The disclosure relates to a portable work apparatus. The work apparatus includes a spacer which is arranged on the front housing and has a contact region. The contact region has a maximum distance, as measured radially, with respect to the rotational axis of the output shaft, the distance being greater than the cutting radius of the cutting tool in a first, non-deformed state of the spacer. The spacer is elastically deformable. The spacer is elastically deformed in a second state in such a manner that the maximum distance of the contact region is at most the same size as the cutting radius, and the spacer is arranged completely outside the cutting plane of the cutting tool.

摘要： A mower deck dual wedge system uses a dual wedge configuration to funnel vine like material for cutting to prevent interference with a spindle shaft. The system includes a mower deck having an upper wall and a peripheral. A spindle shaft extends through the upper wall. Each of a pair of wedges is coupled to and extends from the upper wall of the mower deck. Each of the wedges has a pair of lateral sides extending from a tip. The wedges are positioned on opposite sides of the spindle shaft such that the tip of each the wedge faces away from the spindle shaft. A cutting disc is coupled to the spindle shaft and the wedges are positioned between the cutting disc and the upper wall of the mower deck. The cutting disc is rotated by the spindle shaft.

摘要： A protection system for a rotary cutter, with the rotary cutter including a deck and one or more blade assemblies extending below the deck for cutting vegetation. The protection system comprises a protection annulus associated with one of the blade assemblies, with the protection annulus secured to a bottom surface of the deck and positioned between the deck and the blade assembly. The protection annulus has a width extending from an inner radius of the protection annulus to an outer radius of the protection annulus. The protection annulus has a height extending vertically downward from the bottom surface of the deck. The width of the protection annulus is greater than the height of the protection annulus.

摘要： The present invention relates to a shock-absorption type mower safety blade unit having a protector mounted thereon, the safety blade unit comprising: a housing fixed to a driving shaft of a driving part, provided at the end portion of an operating bar of a mower, so as to rotate together with the driving shaft; a plurality of cutter parts, which are provided at the housing, and project to the outside of the housing so as to cut weeds according to the rotation of the housing and retract to the inside of the housing so as to prevent breakage when colliding with obstacles; and an elastic part for providing elastic force to the cutter parts such that the cutter parts can return by projecting outwards when the cutter parts retract into the housing. The shock-absorption type mower safety blade unit having a protector mounted thereon, according to the present invention, prevents pebbles from being scattered or the cutter parts from being damaged because of the cutter parts retracting to the inside of the housing when colliding with the pebbles or a structure, since the cutter parts are provided to be retractable into the housing and the elastic part supports the cutter parts such that the cutter parts project outward from the housing, and improves mowing efficiency by hitting plants with greater force due to the elastic force provided from the elastic part, when colliding with large plants
