An agricultural machine comprising a connecting structure designed to be laterally mounted to a tractor, the connecting structure including a coupling support, a carrier beam and a transmission unit; the transmission unit including a driving pulley, a driven pulley, a transmission element drive-mounted on the driving and driven pulleys; a work unit articulated to the carrier beam via at least one folding axis, the work unit being fitted with at least one work tool configured to be driven in rotation from the transmission unit. In this machine, the folding axis and the rotation axis of the driven pulley are separate from each other.

A mower deck leveling linkage includes an eccentric leveling plate connecting between upper and lower linkages. The eccentric leveling plate pivots on an off-center axis to change the length of the linkage and level the mower deck.

A ride-on vehicle, such as a zero turn radius lawnmower, includes a main chassis having first and second pivot joints, a first rocker arm having a caster wheel on a first end portion and a drive wheel on a second end portion, and a second rocker arm having a caster wheel on a first end portion and a drive wheel on a second end portion, wherein the first rocker arm and the second rocker arm are independently pivotally coupled to the respective first and second pivot joints of the main chassis at a location between the caster wheels and the drive wheels. The ride-on vehicle may also include a modular mower deck assembly with a plurality of mower deck modules having a blade assembly, an electric blade motor configured to provide rotation to the blade assembly, and an attachment assembly configured to enable attachment between adjacent mower deck modules.

A riding lawn care vehicle may include a frame to which a mobility assembly is operably coupled, an equipment frame operably coupled to the frame forward of the mobility assembly, a steering assembly operably coupled to the mobility assembly to enable an operator seated on the riding lawn care vehicle to provide steering control of the riding lawn care vehicle, a removable cutting in deck and a belt positioning system. The cutting deck includes a rotatable blade and is configured to receive power for turning the blade from an equipment drive belt of the vehicle when the equipment drive belt is operably coupled with the cutting deck. The belt positioning system is configured to enable the equipment drive belt to be automatically operably coupled between the cutting deck and the riding lawn care vehicle in response to the cutting deck being docked with the equipment frame in an operational position.

A storage lock assembly for a lawn mower can include a primary pedal, a lock striker, a secondary pedal, and a deck lock that can be manipulated to selectively lock a mower deck into a stowed position and unlock the deck from the stowed position. The primary pedal can move the deck between a plurality of operating positions and the stowed position. The secondary pedal can include an engagement member and be pivotably attached to the primary pedal. The deck lock can be movable between a locked position where the deck lock is engaged with the lock striker, and an unlocked position where the deck lock is disengaged from the lock striker. When the deck lock is in the locked position and the secondary pedal pivots relative to the primary pedal, the engagement member can move the deck lock away from the lock striker and to the unlocked position.

A mower deck transport lock includes a striker bracket mounted to a rock shaft and extending downwardly and forwardly to engage a height of cut support at any of a plurality of height of cut positions. A transport lock pin positioned adjacent the height of cut support can slide between a first position and a second position. A spring biases the transport lock pin toward the first position and into engagement with the striker bracket to support the mower deck at a transport height above the plurality of height of cut positions. A transport lock disengagement pedal urges the transport lock pin to slide towards the second position to disengage the transport lock pin from the striker bracket.

A height of cut adjustment system for a rough, trim and surround mower deck includes a first height of cut linkage on a left side of the mower deck and a second height of cut linkage on a right side of the mower deck. A connecting rod extends transversely across a top of each mower deck to connect the pair of height of cut linkages together. A height of cut adjustment lever may be secured to the connecting rod. The height of cut adjustment lever may have teeth that engage notches in a pivot plate at each selected height of cut.

A self-propelled mower includes a frame and a mower deck attached to the frame. The mower deck is mounted to the frame in a manner that allows vertical movement and is further mounted to the frame by one or more flexible brackets that allow limited lateral movement of the mower deck relative to the frame of the mower but prevents rearward movement relative to the frame. This allows the mower deck to move relative to the frame when it strikes an object, but stabilizes the mower deck under normal use conditions.

A stand on mower including a pedestal with a deck height adjustment lever positioned adjacent the pedestal for operator use while standing behind the pedestal. A cross yoke, height position lock, and floating height mechanisms are also taught for mounting the deck off of the mower frame.

A grass cutting mobile robot includes a body and a blade assembly connected to the body and rotatable about a drive axis. The blade assembly includes blades, a housing to hold the blades, and a spring that connects the blade to the housing. The housing includes a slot in which to mount a blade so that a portion of the blade is movable through the slot towards another blade in response to an impact. The slot slopes upwards in the housing towards the body, thereby enabling the blade to move upwards relative to a ground surface toward the body in response to the impact. The spring is for constraining movement of the blade relative to the housing.
