An electric power rake is employed in use to care for lawns. The electric power rake includes a deck housing, multiple wheels, a handle, a battery housing, an electric motor, a pulley assembly, and a working shaft, among other possible components. The battery housing is supported on the deck housing. One or more battery cavities resides in the battery housing. A battery, such as a lithium-ion battery, is received in one of the battery cavities and powers the electric motor. The electric motor has a shaft that drives rotational motion in the pulley assembly. The working shaft is driven to rotate via the pulley assembly and has multiple blades that revolve thereabout when the working shaft rotates.

A debris collector and associated systems and methods are disclosed. The debris collector is configured to receive and process debris, such as lawn debris, by way of a variety of intake systems, such as a basket and vacuum tube. After intake, the debris collector is configured to process the debris by way of an auger and agitators, so as to be passed through a blower fan for disposal.

A blower includes a first fan stage with a first housing that has a first plurality of stationary vanes and a first fan that has a first plurality of blades extending radially outwardly from a first hub. The first housing includes a first axial end and a second axial end opposite the first axial end. The blower also includes a second fan stage coupled to the first fan stage. The second fan stage includes a second housing with a second plurality of stationary vanes and a second fan that has a second plurality of blades extending radially outwardly from a second hub. The second fan stage includes a third axial end and a fourth axial end opposite the third axial end. The first hub and/or the second hub has a frustoconical shape that converges from the first axial end toward the fourth axial end.

A power group includes: an engine, and a shoulder support for the engine. The shoulder support includes: a support frame adapted for supporting the engine, the support frame having an L-shape and a vertical first portion and an horizontal second portion cantilevered associated with the first portion and to which the engine is connected at the top of the horizontal second portion to be supported thereon; a wearable framework connected to the support frame, and a damper element interposed between the support frame and at least one element of which the wearable framework is made up. A first element, of which the wearable framework is made up, includes a lumbar support and the damper element includes a first damper interposed between the lumbar support and the support frame.

A leaf collection assembly for collecting leaves falling from a tree includes a collar that is positionable around a trunk of a tree. A plurality of arms is provided and each of the arms is coupled to and angles upwardly from the collar when the collar is positioned around the trunk of the tree. A screen is attached to the collar and each of the arms such that the screen forms a cone when the collar is positioned around the trunk of the tree. In this way the cone captures leaves falling from the tree. A pair of chutes is provided and each of the chutes is coupled to the collar. Each of the chutes is aligned with the cone to direct the leaves outwardly from the cone for bagging the leaves.
