Ways to cut the cost

  • 1

    Switch from gas to electric mower

    Eliminates gas; electric mowing costs ~$5/year vs ~$50 for gas

  • 2

    Mulch instead of bag — less motor load

    Saves 10-20% of runtime energy

  • 3

    Keep blade sharp — dull blades force more motor current

    Restores 15-25% of efficiency
