Multi-blade cutting platform for electric walk-behind maintenance apparatus

A multi-blade assembly for a walk-behind power equipment device, comprising:

• a first blade elongated along a first blade axis to define a first blade center offset from a first blade edge by a first blade length;
• a second blade elongated along a second blade axis to define a second blade center offset from a second blade edge by a second blade length;
• a blade adapter defining an axis of rotation that secures the first blade in a fixed orientation relative to the second blade, with the second blade underlying the first blade, wherein the first blade length is greater than the second blade length;
• wherein the blade adapter platform comprises
• a mounting plate,
• one or more blade fasteners secured to the mounting plate, and
• an adapter portion having a perimeter shape configured to receive a blade having
• a blade cutout that matches the perimeter shape;
• the adapter portion includes a dimple protrusion adjacent the perimeter curvature at a top surface of the mounting plate and extending upward from the mounting plate along the perimeter curvature;
• the second blade includes a dimple cutout that matches the dimple protrusion allowing the second blade to seat conformally over the dimple protrusion and rest on the top surface of the mounting plate;
• and
• the first blade does not include the dimple cutout and is prevented by the dimple protrusion from movement along the perimeter curvature past the dimple protrusion.
