Better Quality Control
Line binds on spool. More quality control. Plastic line may be difficult to put on spool with machine (causing extensive heat that melts plastic as it spools) which makes quality control harder. I love the convienence of pre wound, but the agrivation of continuously reloading line is unnerving.

How much line is on the replacement spool trimmer line 29622?
Ron on Aug 4, 2016
BEST ANSWER: The 29622 comes with 30 feet of trimmer line.
The manual says "Remove the empty spool from the string head." How do you do that?
I got this far: "Remove the spool retainer... turn clockwise". I'm left with the object in my hands so I think I'm following instructions. I can't get that object to come open. Is the 'string head'something different from the 'spool retainer'?

Do they make other accessories, i.e. hedge trimmers, saws for the 21142 power head?
Paul on May 27, 2015
BEST ANSWER: No, Greenworks does not make any different attachments for their trimmers, which is model # 21142.
Will the Greenworks dual line .065 line spool fit on trimmer attachment 29402 . The original bump head is .080 line ? And is there any universal head from another common brand that adapts to this trimmer? Bump feeder #29622 (part# from Greenworks) is VERY hard to find and backordered!
Mosey on May 12, 2015
BEST ANSWER: Yes, the smaller diameter line will work. CPO does not retail a universal head to replace the 29622.
Please advise of all locations where the model grass trimmer unit, 21142- trimmer line, #29622 may be purchased @?

I am looking for the "best price", based upon various quantities or just one spool, thank you. Paul
