The way I’ve done it is I pull the line out of one reel…down the drive way, around a tree and then back towards the garage agian.
Once I have one spool free, I use that free spool to take the line off of other reels. When I’m done, I’ll have one reel left empty (except for backing) then I take the old end of the line and reel that in.
Sometimes…like this year, I’ll have a reel that the PP has been broke off too many times. I’ll use that reel as my “starter” reel and end up putting fresh on the last reel.
That’s the way I do it…
