Where to Buy

The TB685 EC gas weed trimmer with SpringAssist™ technology and JumpStart™ capability features the new Quick Change™ bump head, making line replacement easier than ever. The TB685 EC weed trimmer comes equipped with a .095" cutting line that creates a 17" cutting swath and an adjustable Pro handle for both right and left-handed use. The EZ-Link® attachment system provides the ability to use any TrimmerPlus® trimmer attachment to tackle multiple tasks with one weed trimmer.


  • No Mixing Oil and Gas

    Eliminate the need to mix oil and gas. Troy-Bilt’s 4-cycle engines take regular gas.

  • Quick Change™ Bump Head

    The Quick Change™ cutting head option makes it easy to refill without disassembling the cutting head. Simply feed the line through the eyelets, and then twist the head to wind the line in seconds.

  • SpringAssist™ Starting Technology

    SpringAssist™ starting technology dramatically reduces pulling effort by up to 55%.

  • JumpStart™ Capable

    Take the effort out of starting with JumpStart™ power start technology. Attach JumpStart to any JumpStart-capable Troy-Bilt® unit and start with the push of a button.
