Definitions

  • the present subject matter relates generally to snow shovels, and more particularly to motorized snow shovels which include rotatable augers.
  • Snow shovels are widely utilized to move snow and other environmental debris. For example, a common use of a snow shovel is to remove snow from a driveway and/or sidewalk. However, most known snow shovels are purely manual tools requiring manual labor during use. In some situations, such manual labor can be detrimental or dangerous, such as in the case of the elderly or those with health conditions.
  • snow blowers can be expensive and complicated to operate, and generally blow snow into the air during operation. If there is a breeze during operation of the snow blower, the snow can be blown into unintended locations, including for example into the user.
  • a motorized snow shovel in accordance with one embodiment, includes a shaft assembly extending along a longitudinal axis between a first end and a second end.
  • the motorized snow shovel further includes a handle assembly connected to the first end, the handle assembly including a first handle.
  • the motorized snow shovel further includes a head assembly connected to the second end.
  • the head assembly includes a shovel, an auger rotatably connected to the shovel, and a motor operational to rotate the auger.
  • a motorized snow shovel in accordance with another embodiment, includes a shaft assembly extending along a longitudinal axis between a first end and a second end.
  • the motorized snow shovel further includes a handle assembly connected to the first end, the handle assembly including a first handle, a battery, and a trigger.
