Rotary mower with cutting deck with bidirectional cutting blades
11730083 · 2023-08-22 · ·

A rotary lawn mower has one or more grass cutting blades that are rotatable in opposite directions about a vertical axis or axes. Each blade is double edged having front and rear cutting edges on each end of the blade. Each blade end has a front sloped face inboard of the front cutting edge and a rear sloped face inboard of the rear cutting edge. These faces create air flow within the cutting chamber when cutting grass regardless of the direction of rotation of the blade. The direction of rotation of each blade is reversed to switch between discharge and mulching modes of operation. A flow director has a curved vertical guide wall that guides the grass clippings through a discharge opening in the discharge mode and that guides the flow of grass clippings away from the discharge opening in the mulching mode.

FLEXIBLE MOWER DECK

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.

A mowing machine may include a central cutting deck generally disposed in a neutral mowing plane and a wing cutting deck pivotable with respect to the central cutting deck. A main gearbox may be connected to a wing gearbox by a wing driveline. The main gearbox may be disposed a sufficient distance forward of the central cutting deck and the wing cutting deck to permit the wing cutting deck to pivot about a hinge in a range of motion without disconnecting the wing driveline from either the main gearbox or the wing gearbox.

A lawn mower comprises a driving assembly, an impact protection assembly, a transmission assembly and a cutting assembly. The impact protection assembly comprises a first bearing seat and a second bearing seat which are mated with each other, and an elastic member and a ball which are positioned between the first bearing seat and the second bearing seat. The first bearing seat is provided with a protrusion. When the driving assembly performs driving, the ball is pushed by the elastic member to be in contact with the protrusion of the first bearing seat, so that the transmission assembly and the cutting assembly are driven to rotate synchronously. When the resistance received by the cutting assembly is greater than a preset value, the elastic member is continuously compressed and the ball passes over the protrusion, and a relative rotation between the transmission assembly and the driving assembly occurs.

A tool head for a hand-guided implement possesses two rotatably mounted tools, wherein a first tool is drivable via a first linkage and a second tool is drivable via a second linkage. The tools are drivable so that they rotate back and forth in opposite directions about a common rotational axis. The first linkage possesses a first drive member coupled to a first coupling member pivotably about a first link axis. The first coupling member is coupled to the first tool pivotably about a second link axis. The second linkage possesses a second drive member coupled to a second coupling member pivotably about a third link axis. The second coupling member is coupled to the second tool pivotably about a fourth link axis. The rotational axis of the tools and the coupling drive axis span a center plane, which runs between the second link axis and the fourth link axis.
