Quick release blade assemblies for a power tool are provided. A lawnmower includes a base including an engagement interface; a retainer having a locking component; a blade disposed between the base and the retainer; and an actuatable member including an engagement member, the engagement member being selectively displaceable with respect to the engagement interface between a locked configuration and an unlocked configuration when the actuatable member is translated in a direction parallel with the axis of rotation, wherein the engagement member is configured to interface with the locking component to selectively couple the blade to the drive shaft when the engagement member is in the locked configuration.

A low-energy blade system having a quick-change attachment for a lawn maintenance tool is provided. The low-energy blade system requires a reduced amount of energy to rotate the blade system. The blade system includes a shell, a mounting plate attached to the shell, a plurality of quick-attach mechanisms, and a separate cutting blade attachable to each of the quick-attach mechanisms. Each quick-attach mechanism allows a cutting blade to be attached to the mounting plate without the need for external tools, such as screwdriver, wrench, ratchet, or the like.

A reversible line blade for a rotating trimmer includes a loading section configured to be securable for rotation with a head of the rotating trimmer, a living hinge extending from the loading section, a transition section extending from the living hinge, and a cutting segment extending from the transition section. At least one of the transition section and the cutting segment has a cross-sectional shape that is configured to generate an updraft when the line blade is rotated clockwise and when the line blade is rotated counter-clockwise.

A manufacturing method for a mower cord and including pressing a resin wire rod and plastically deforming at least part of the wire rod in an axis perpendicular direction. Work-hardening of a surface of the plastically deformed portion allows dramatic enhancement of mowing efficiency.

This specification describes improvements to cutting blades and a cutting blade assembly. In some forms the cutting blade includes an upturn with an upturn radial angle which is non-parallel to a reference axis.

Trimmer heads for trimmers are provided. A trimmer head includes a drive plate defining a lug slot, and a locking lug, the locking lug movably positioned in the lug slot and movable between an unlocked position and a locked position. A trimmer head further includes a drive plate cover connectable to the drive plate such that the locking lug is disposed between the drive plate and the drive plate cover. A trimmer head farther includes at least one operational head, the at least one operational head connectable to the drive plate. The connected operational head is locked to the drive plate when the locking lug is in the locked position and the connected operational head is unlocked from the drive plate when the locking lug is in the unlocked position.

A cutting blade for vegetation is provided for example for use in a straw chopper or rotary mower. The blade body includes a first base material and at least one hard surface bead formed on at least one surface of the base material extending up to a cutting edge of the base material. Beads can be applied longitudinally by the heat energy from the cladding laser system to form pockets so that the blade is serrated by the pockets when supplied with additional wear increasing the pockets to maintain the serrations. The chamfered side face of the blade body forming the cutting edge can also be formed using heat energy from the same laser cutting and cladding system.

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.
