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.

A rotary cutterbar disk hub assembly for diverting debris includes a cutterbar housing defining an internal cavity and a bearing housing defining an axis and coupled to the cutterbar housing. A labyrinth is defined in the bearing housing circumferentially about the axis, and a barrier is formed by the bearing housing at a location radially outward of the labyrinth. A disk hub is positioned concentric with the axis and coupled to the bearing housing and cutterbar housing. The disk hub forms at least one protrusion that extends towards the bearing housing and is radially adjacent to the labyrinth. The barrier restricts a portion of the debris from entering the labyrinth, and the at least one protrusion severs debris that is disposed near the labyrinth as the disk hub rotates.

A modular cutterbar assembly capable of moving in a direction of travel may include a first module forming a first surface, a second surface, a front edge, and a rear edge. The assembly may also include a second module coupled to the first module such that the second module forms a first surface, a second surface, a front edge, and a rear edge. A joint is defined between first and second module and defining a joint plane. A first coupler is defined through the joint of the first and second modules at each respective front edge and defining a first coupler axis, and a second coupler is defined through the joint of the first and second modules at each respective rear edge and defining a second coupler axis. The joint plane is angled relative to the direction of travel.

In certain example embodiments of this invention, the lawn mower includes one or more of: (a) cutter deck baffle teeth for improving cutting performance; (b) a trim divider edge portion of the cutter deck for improving cutting performance; (c) a trim vacuum structure portion of the cutter deck for improving cutting performance; and/or (d) a center vacuum structure portion of the cutter deck for improving cutting performance.

An elongated rotary cutterbar assembly includes a housing having a first surface, a second surface, a front portion, and a rear portion. At least one disk is rotatably coupled to the housing, and the assembly further includes a first tab at least partially disposed between the first surface and the second surface, and a tab plane defined by the first tab and extending between the first surface and the second surface. A stop surface is defined in the housing offset from the tab plane towards the first surface, and a disk guard is coupled to the housing at the first tab. A receiver is defined in the disk guard at a location adjacent to the first stop surface. When a force is applied to the disk guard towards the first surface, the first receiver contacts the first stop surface to restrict deflection of the disk guard relative to the housing.

The disclosure relates to a feedback assembly for a harvester useful for providing feedback regarding operation of one or more blade assemblies of the harvester. The feedback assembly comprises a chassis, one or more rods coupled to the chassis, and one or more tines rotatably coupled to the one or more rods. Each of the one or more tines defines an elongated body including a linear section extending from the one or more rods, and an angled section extending at an angle from the linear section. Each of the one or more tines is configured to hang substantially perpendicularly relative to a direction of travel of the harvester when in a non-actuated position. The one or more tines are configured to rotate away from the direction of travel of the harvester when in an actuated position.

In certain example embodiments of this invention, the lawn mower includes one or more of: (a) cutter deck baffle teeth for improving cutting performance; (b) a trim divider edge portion of the cutter deck for improving cutting performance; (c) a trim vacuum structure portion of the cutter deck for improving cutting performance; and/or (d) a center vacuum structure portion of the cutter deck for improving cutting performance.

A harvesting header has a set of centrally disposed conditioner rolls comprising conditioning structure to condition crop and a rotary cutter bed. The rotary cutter bed has a plurality of rotary cutters extending across the path of travel of the header to define a cutting plane, each cutter being rotatable about an upright axis, the conditioner rolls being behind the cutter bed to condition crop cut by the rotary cutter bed. The header has a crop-directing header windguard configured to direct the crop down towards the conditioning rolls after the plurality of cutters have severed the crop, the header windguard extending in a rearwardly direction from a position forward of the cutter bed to a position proximate the conditioner rolls, and the header windguard extending transversely at least a width of the rotary cutter bed.

A mid-mount mower has a mower unit mounted under a vehicle body between front wheels and rear wheels. The mower includes a lift link mechanism having a front link and a rear link, an intermediate structure interconnecting one end of the front link and one end of the rear link via a pivot axis, a blade housing having an engaged portion engageable with an engaging potion of the intermediate structure and a guide face configured to guide the engaging portion ad the engaged portion to an engaging position so as to establish connection between the blade housing placed on a ground surface and the intermediate structure in association with a movement of the vehicle body in a front/rear direction.
