  • CONVENIENT- Never-go-flat wheels ensure that your equipment is ready to go when you are.  An integrated clutch and hand bail system safely keeps the String Mower motor running, but disengages and stops the trimmer head if you need to clear debris, eliminating the need to re-start your motor each time.
  • OUT-OF-THE-BOX: The setup is super simple with virtually zero assembly required. Simply unfold and tighten the tool-less handlebar knobs. Also included in the box are starter strings for the mower head and 4 cycle engine oil.
