Can't find any replacement string for ST1502SF. None of the replacement string products specify "for use with ST1502SF.
Thanks, Jacob. And do you buy it in like a cartridge? Or do you wind it onto your factory Ego spool? Oh...I think the thing is that maybe I just don't get too hung up on the details. The model number of my mower is I think 1502SF. But maybe if I just buy Ego replacement spools for 1500...that will be okay...?
