KA, always enjoy watching your video reviews. That said; I do like the Powerload bump head and the Carbon Fiber shaft. Hard for me to let go of my 1st Generation 15" EGO trimmer though, as that tool works perfectly for me week in and week out. Like OM, if EGO makes a retrofit Powerload bump head for my 1st Gen, then I will definitely consider it. For now, I will wait when a "sale price" comes around for this new trimmer - thanks for the video!
A retrofit would definitely not work. There is a one way Mechanism, a Motor reversing circuit. So the electronics will be completely different. Reversing circuit only switches 2 of the wires but it would have to send a signal to the controller. Pretty much will cost the same as new.
So I assume this reversing function prevents EGO from offering this Power Load feature with carbon fiber shaft to be made into an optional appliance for the Power+ Multi-Head system? This would be a wonderful option for those of us who have committed to investing in the Multi-Head system if EGO could figure that one out - Even if we already own the older generation 15" string trimmer as I do!
