A control unit of a lawn mower performs switching control for switching operation between a first control mode and a second mode. In the first control mode, during rotation of an engine at a first reference rotation speed, in the case where a change amount of rotation speed of the engine per unit time has exceeded a reference speed change amount, the rotation speed is maintained at a second reference rotation speed, and an flap angle is increased. In the second control mode, during rotation of the engine at a second reference rotation speed, in the case where an opening angle of a throttle valve has fallen below a reference opening angle, the rotation speed is maintained at the first reference rotation speed, and the flap angle is decreased. The second reference rotation speed is higher than the first reference rotation speed.

A lawn mower includes a housing having an opened bottom, a drive source for driving the cutter blade in the housing, a flap provided for the cutter blade in a manner that the flap has a changeable flap angle, a grass clippings container storing cut lawn grass, a grass clippings container weight detection unit for detecting weight of the grass clippings container, and a control unit. The control unit controls at least one of the rotational speed of the drive source and the flap angle of the flap in correspondence with the weight detected by the grass clippings container weight detection unit.

A lawn mower contains: a work unit including a housing having a downward-facing opening and a cutter blade rotatably provided in the housing such that when rotated, the cutter blade cuts grass and generates a transport air flow flowing from the opening of the housing to inside; a grass clippings receptacle configured to receive grass clippings cut by the work unit; a grass clippings transport passage connecting an interior of the housing with the grass clippings receptacle; a shutter device including a shutter configured to selectively open and close the grass clippings transport passage and an actuator configured to drive the shutter; a controller configured to control the shutter device; and a pressure sensor provided in the grass clippings transport passage to detect a pressure in the grass clippings transport passage, wherein the controller is configured to control the shutter device in accordance with the pressure detected by the pressure sensor.

A work vehicle includes a cutter device for cutting plant in a field, a storage section for storing plant cut by the cutter device, an inclination angle sensor for detecting an inclination angle ((d)) of the vehicle body, a display device for displaying the inclination angle detected by the inclination angle sensor, and a reporting device for reporting the inclination angle exceeding a permissible inclination angle ((a)).

A lawnmower comprising: a body; a cutting element coupled with the body; a motor configured to drive the cutting element; a sensor comprising an accelerometer configured to detect an angular displacement of the lawnmower with respect to a vertical axis and a wobble of the cutting element with respect to a horizontal plane; and a processor configured to: compare the detected angular displacement against a tilt threshold value; compare the detected wobble against a wobble threshold value; and control an operational speed of the cutting element when the angular displacement exceeds the tilt threshold value or when the wobble exceeds the wobble threshold value.

A lawn mower includes a mower frame, a prime mover supported by the mower frame, a mower deck mounted to the mower frame, a cutting blade mounted below the mower deck to cut vegetation under the mower deck, and a bagger assembly releasably coupled to the mower frame. The bagger assembly includes a receptacle for collecting cut vegetation. The receptacle has a lid. The bagger assembly also includes a latch supported by the receptacle and operable to engage the mower frame. The latch is moveable between a first position, in which the latch is secured to the mower frame, and a second position, in which the latch is released from the mower frame. The bagger assembly further includes a cord positioned on the lid and coupled to the latch. The cord is operable to move the latch from the first position to the second position.

Lawnmowers are provided. A lawnmower includes a seat; a first battery receiving area defining a plurality of compartments, wherein the first battery receiving area is disposed behind the seat; a second battery receiving area configured to receive a second battery, wherein the second battery receiving area is disposed over a wheel of the lawnmower; a plurality of first batteries each removably receivable in one of the plurality of compartments; and a second battery removably receivable in the second battery receiving area, wherein the second battery is smaller than each of the plurality of first batteries, wherein the lawnmower is operational without the second battery electrically coupled to the lawnmower.

Lawnmowers are provided. A lawnmower includes a first battery having a first voltage, the first battery mounted on the lawnmower; a second battery having a second voltage different than the first voltage, the second battery mounted on the lawnmower; and a booster configured to boost the second voltage to the first voltage, wherein the booster is connected to a common rail operating at the first voltage.

A mulch plug accessory for a lawnmower includes a curvilinear plug wall having a convex side, and a plurality of alignment legs extending in a direction away from the convex side of the curvilinear plug wall. Each alignment leg has a distal end including a stop flange. The mulch plug accessory further includes a post extending in a direction away from the convex side of the curvilinear plug wall. A lawnmower including a main body having an ejection port also includes a mulch plug accessory configured to be selectively disposed within the ejection port.

Collection vessel fill-indicator assemblies and mowers with collection vessel fill-indicator assemblies are provided. A collection vessel fill-indicator assembly includes a capacitance element configured to be disposed adjacent to a collection vessel of a mower to detect a fill state of the collection vessel; and an interference guard disposed around a portion of the capacitance element to shield the capacitance element from interference.
