    Cuttin-to-the-max, take the head off and see if the shaft spins freely. If it does, your clutch is probably worn out so the engine will rev but not transfer the power to the driveshaft.

    That or you've seized the bearings in the head.

    Either case it's a relatively easy fix.

    ok well i just checked it...didnt have too much time had to watch the kids.. but i checked the trimmer. The head spins freely all the way around as it should. But also i would like to ad when i start the whip it sounds fine (on idle) Then when i squeeze the trigger the head budges the squeals....

    White gardens: Still an easy fix?? lol Thumbs Up

    Its probably a broken clutch spring. One of my Shindaiwa's doing the exact same thing and the spring was broken. It was a couple of dollars for a new one.

    Take the driveshaft housing off and check the clutch. You could have a worn clutch drum as well.

    Still an easy fix, I second the clutch as others have stated.

    Ok so today I took of the trimmers head...
    I gotta find my set of Tex wrenches to get the gear head off.
    I thought my allen wrenches were going to get it off but it's a star. I swear my guys either borrow or steal my tools (and never bring them back) I know I have/ had at least 3 of those.


    I pulled the trigger with the head off and I can hear something turning in the gearhead area (on the opposite side of the motor)
    I dont know....., I'll have to open it up tomorrow.

    Many have suggested this for me. Others have just suggested that a screw is loose. Only family members and close friends can help you out with this one. :)
