Apparatus for trimming and edging grass around a lawn sprinkler head

A method for edging and trimming grass around a lawn sprinkler head, said method comprising:

• providing an apparatus that includes a drive mechanism having a rotary auger motor with a rating of two-horsepower to four-horsepower, a handle attached to the motor and a drive shaft connected to and rotatably driven by the motor, an elongate rotary shaft that is at least 18″ and not greater than 30″ in length, an annular blade that is axially aligned with and attached to the rotary shaft proximate a lower end of the rotary shaft and means for releasably attaching the rotary shaft to the drive shaft such that the rotary shaft and the drive shaft are axially aligned;
• standing upright, grasping the handle and positioning the blade over the sprinkler head and against the grass while the motor is deactivated;
• and
• starting the auger motor to rotatably drive the blade against the grass, whereby the grass against which the blade is positioned is edged and trimmed.

An apparatus for edging and trimming grass around a lawn sprinkler head, said apparatus comprising:

• a drive mechanism including a rotary auger motor have a rating of two-horsepower to four-horsepower, a handle attached to said motor and a drive shaft connected to and rotatably driven by said motor;
• an elongate rotary shaft that is at least 18″ and not greater than 30″ in length;
• an annular blade that is axially aligned with and attached to said rotary shaft proximate a lower end of said shaft;
• and
• means for releasably attaching said rotary shaft to said drive shaft such that a user standing substantially upright, grasping said handle of said auger motor and engaging said annular blade with the grass surrounding the sprinkler head operates said motor to drive said rotary shaft and said annular blade axially rotatably, whereby the engaged grass is trimmed and edged by said annular blade;
• said rotary shaft including a tubular member for receiving said drive shaft, said tubular member having a pair of opposing transverse holes formed proximate an upper end thereof, said drive shaft including a transverse hole that is alignable with said transverse holes in said tubular member, said means for releasably attaching including a connector that is insertible through said opposing holes in said tubular member and said transverse hole in said drive shaft and means for provisionally holding said connector in place to releasably interconnect said rotary shaft and said drive shaft.
