Electric wood chipper shredder mulcher uses a 15 A motor and dual-edge metal blades to turn branches and yard waste into mulch quickly. The maximum 1.8-in cutting diameter accepts larger limbs, while the 21:1 reduction rate reduces bulk so more debris fits in the 13.2-gallon collection bag before you need to empty it. A push paddle keeps hands away from the intake for more controlled feeding, and overload protection helps protect the motor during tough jobs.
