Abstract
A low-energy blade system having a quick-change attachment for a lawn maintenance tool is provided. The low-energy blade system requires a reduced amount of energy to rotate the blade system. The blade system includes a shell, a mounting plate attached to the shell, a plurality of quick-attach mechanisms, and a separate cutting blade attachable to each of the quick-attach mechanisms. Each quick-attach mechanism allows a cutting blade to be attached to the mounting plate without the need for external tools, such as screwdriver, wrench, ratchet, or the like.
Claims15
A low-energy blade system for a lawn maintenance tool, said blade system comprising:
- a shell having an upper surface and a lower surface;
- a mounting plate attached to said lower surface of said shell;
- a plurality of cutting blades releasably attachable to said mounting plate;
- and
- a plurality of quick-attach mechanisms operatively connected to said mounting plate, wherein each of said cutting blades is operatively connectable to one of said quick-attach mechanisms.
A low-energy blade system for a lawn maintenance tool, said blade system comprising:
- a shell having an upper surface and a lower surface;
- a mounting plate attached to said lower surface of said shell, said mounting plate includes a plurality of caps;
- a plurality of cutting blades, each blade being releasably attachable to one of said caps of said mounting plate;
- and
- a plurality of biasing members attached to said mounting plate, wherein each of said biasing members biases one of said plurality of cutting blades into a positive attachment with said mounting plate.
A low-energy blade system for a lawn maintenance tool, said blade system comprising:
- a shell having an upper surface and a lower surface;
- a plurality of caps operatively connected to said lower surface of said shell;
- a plurality of cutting blades, each blade releasably attachable to one of said caps;
- and
- a plurality of biasing members operatively connected to said shell, wherein each of said biasing members biases one of said plurality of cutting blades into a positive attachment with one of said plurality of caps.
