A lawnmower can include a frame; a mower deck; and a connection interface that selectively couples the mower deck to the frame, wherein the connection interface is selectively lockable in an open state to permit installation of the mower deck to the frame, and wherein the connection interface is spring biased to a closed state to lock the mower deck and the frame together.

An adjustable lift rate system on a grass mowing machine such as a riding greensmower having a lift and lower circuit including a plurality of hydraulic lift cylinders to lift and lower a plurality of cutting units, and a controller providing a current to a proportional solenoid valve to bypass the hydraulic lift cylinders. An operator control may be used to adjust the current to the proportional solenoid valve to adjust the lift and lower rate of the cutting units.

Disclosed is a mower unit including, on a mower deck that rotatably supports a blade, a deck-side electric component configured to drive the blade, and a joint section for effecting connection and disconnection of a harness that electrically connects the deck-side electric component to a vehicle body-side electric component.

A latching assembly (100, 100) for operably coupling a cutting deck (50) to an equipment frame (60) of a riding lawn care vehicle (10) may include a pivot arm (300, 400), and a latch member (310, 410). The pivot arm (300, 400) and the latch member (310, 410) may each be pivotally coupled to each other. The pivot arm (300, 400) and the latch member (310, 410) may also cooperate with each other to affix the cutting deck (50) to the equipment frame (60) in each of a service position and a working position.

A mower deck is provided herein. The mower deck includes a housing having a top plate and a downwardly extending wall that depends from a substantial portion of a perimeter of the top plate. The housing includes an attachment member configured to hingedly couple the housing to equipment such that the housing may rotate through a plurality of positions. First and second blades are disposed within the housing configured to rotate in respective first and second directions. A driving unit is operatively connected to the first and second blades. A flexible transmission is coupled to the power source of the equipment and configured to power the drive unit, wherein the transmission is operable at each of the plurality of positions of the housing.

According to an embodiment, a riding-type mowing apparatus, in which a mower unit is disposed below a body frame to mow grass through a blade mounted in the mower unit and a driver seat is provided on the body frame, includes: a steering lever provided on both sides of the driver seat to operate traveling of the riding-type mowing apparatus; a brake pedal provided on a bottom frame disposed in front of the body frame to brake the riding-type mowing apparatus; and a lift-down pedal and a lift-up pedal disposed on both sides of the brake pedal to lift-down and lift-up the mower unit, respectively.

A lawn-mowing vehicle is provided in which a facing-the-ground surface of a lawn-mowing unit can manually be shifted. The lawn-mowing units of the lawn-mowing vehicle can be rotated. There is provided a first connection mechanism that connects each of the lawn-mowing units to the arm, in such a way that the lawn-mowing units can be shifted by rotation between their work positions and the biased side positions that are biased toward the sides of the carriage. There is provided a second connection mechanism that connects each of the lawn-mowing units to the first connection mechanism so as to be rotatable, in such a way that the lawn-mowing units placed at the biased side positions can be shifted from a facing-the-ground posture to an outward posture.

A reduced weight underbelly mower has a cutting deck suspended beneath a frame by a deck height adjustment mechanism with a pivotable scissor configuration. The deck height adjustment mechanism cooperates with the mower frame so as manually or through a motorized jack to adjust the cutting height. Due to the mower's reduced weight and the scissor-like configuration of the deck height adjustment mechanism, an operator can manually lift the mower front end and swing the deck rear swinging forward, such that the mower rests stabilly on the deck rear and the deck underside is exposed for maintenance procedures.

An implement coupling arrangement, typically for use with a lawn care vehicle (1), comprising a first part arranged to be coupled to a vehicle (1) and a second part arranged to be selectively mounted on the first part, in which the first part comprises a support arm (5) configured to support the second part, a mounting (6) for moveably mounting the support arm (5) relative to the vehicle (1), and a biasing member (7) arranged so as to bias the support arm (5) upwards relative to the vehicle (1), in which the second part comprises an implement (9) and a mounting assembly (8), the mounting assembly (8) and the support arm (5) being interengageable so as to mount the second part on the first part; and in which the arrangement further comprises a locking mechanism (10), which has a locked state which inhibits movement of the support arm (5) upwards relative to the vehicle (1) beyond a point, and an unlocked state which allows upward movement of the support arm (5) relative to the vehicle (1) beyond the point; in which disengagement of the mounting assembly (8) from the support arm (5) causes the locking mechanism (10) to enter the locked state.

An autonomous robotic lawnmower (1) is disclosed. The robotic lawnmower (1) comprises a driving unit (3) comprising one or more drive wheels (5) and a cutting unit (7) arranged to cut grass when in a cutting position relative a ground surface (9). The lawnmower (1) further comprises a folding mechanism (11) allowing the cutting unit (7) to be pivoted relative the driving unit (3) around a pivot axis (ax) from the cutting position to a pivoted position.
