Once assembled, there is no difference. The split shaft version was made to keep the retail box smaller, but the assembly is meant to be permanent. You wouldn't want to try to take it apart to store in the winter or anything.

I'm not even sure that any retailers are actually carrying the non-split version.

To add to what David said, the split shaft trimmer is Ego's 15-inch trimmer, which is considerably more powerful, has a brushless motor and is variable speed.

The non-split shaft is Ego's 12-inch trimmer, which predates the 15-inch. It doesn't have a brushless motor, is less powerful, and a lot of people have trouble with the bump head feeding properly (which is sometimes corrected with a different brand of string).

The 15" trimmer also has a non-split version, at least in theory. There was a post and discussion about it last year on this site and Jennifer confirmed that it does exist—but we never found any authorized dealer selling it (at least not online). Perhaps a local Ego retailer that isn't Home Depot might have some on the shelf?

where is the non-coupler version available for sale? the Model No. ST1500? (the non "S" version)

I personally own a non-split shaft 15", so I can attest that it very much exists!  ;)

Yep. Mine is NOT split shaft. And it is a 15" trimmer

Where on earth did you guys find one? And Jacob, where were you on that post last year where someone was looking for that version??

I'll be honest, I have no idea what it even looks like because I've never seen one anywhere!

Looks just like the one on the cover of the manual! :-)

I have a "split shaft" like most people, but I can see one advantage to having a "straight shaft" - the ability to move the "anti-vibration" handle down the shaft further than the "split shaft."  For those who have longer arms and need to extend their handlebar might find this to be a better option.

David and Ken are correct.  There's no real difference other than the size of the box.  The split shaft was only available at the Home Depot and the straight shaft was available at some authorized dealers.  There's no functionality difference in the tools. This was only an option with the 15" string trimmer.

Isn't there a difference in the ability to add attachments, though? Like, can't you hook up an edger to the split-shaft, but not the straight?

The attachments are only compatible with our Power Head Multi-Tool system.

Only the power head allows for attachments / changing the tool end.
The trimmers are stand alone single purpose tools

One difference is that with the straight shaft, you can position the handle further down the shaft; where as with the split, you can go no lower than the split mechanism. I have the split with a 2.0/2.5 battery, the handle is adjusted as low as it will go.  The balance is towards the rear (neutral would be about 1/2 way between the split and the handle), but in that position, the handles feel too close together.

Is there any long term advantage to having the one piece vs split?  Is the one-piece fewer places for a failure (no connection) or is it fewer places to replace a failed part (top or bottom half)?   I see I can order either online and am trying to figure out if I want the one-piece straight shaft or the standard in-store split shaft.

Tom, both versions have been proven to be equally trouble free.  I have the straight shaft and it works great, no issues, and lots of people report that the split shaft version is super solid once set up.

This appears to be an old thread, but I was wondering the same thing. What is evident to me is that you can detach the split shaft and add on another attachment, such as an edger.

The trimmers are stand alone single purpose tools.  The split shaft makes the package smaller for shipping.  Once you put the string trimmer available it is essentially a straight shaft tool.
