This conversation has been merged. Please reference the main conversation: Reversing spin of trimmer

This is a feature that Husqvarna integrated into their cordless string trimmers, so I know it can be done.  There are a bunch of people who have used gas-powered trimmers and I didn't notice this until recently because I'm not one who has used gas, but the EGO trimmer spins the opposite direction that trimmers like Stihl's FS-90-R and various Echo trimmers.   It would be very good for some people to be able to make the trimmer spin the other way if needed.  That would be something I'd do just to keep debris from going somewhere I don't want it to go.

While I like the idea, it wouldn't work.  The cord is wound and it is designed to run in the direction it spins.  To reverse it, I doubt the line feed would work and the blade to cut the excess would have to be put on each side of the guard.

Here is a thread with which direction the ST1500 and PH1400/STA1500 spin:
Another member re-wired his ST1500 to run backwards, but I think he found the bump head would not advance correctly (as would be expected).
The Echo Speed Feed 400 head I put on temporarily had the ability to switch the direction of the bump head, but  you still need to address the other two changes: a) motor direction, and b) blade cut off location (as SCDC said):

I would make the blade cut-off double-sided.  Again, I noted that Husqvarna has a trimmer that can have its spin direction changed with the push of a button, so how did they do it?

Requiring the bump head to be spinning in one particular direction to feed would be fine with me.

With residential trimming you're not bumping the line all the time so flipping a switch to reverse the direction of the trimmer to bump feed every now and then wouldn't be the end of the world.

In cases where you are bumping frequently, like clearing heavy brush, I don't think you're very concerned about which way the trimmer is spinning so you could easily use the direction that facilitated bump feeding.

Just my thoughts. Having the option to reverse the trimmer would definitely be a plus compared to having no option as we do now, and it wouldn't cost a fortune to implement this feature on the tool.
