Ryobi
40V HP Brushless 16 in. Cordless Carbon Fiber Shaft Attachment Capable String Trimmer with 4.0 Ah Battery and Charger
Reel Easy + Bump Feed Head
Model #: AC053N1BFH
Each attachment has it’s time. When the blackberry was eight feet tall, needed to use mower and .130 line. To maintain, moved to .095 with pivotrim for fence. Bump head now seems like the best choice to move to.
UPDATE 7/4/2025
The Ryobi bump head works OK, but the refilling line by turning green bump head knob is a tad tough for my taste. Bought a Speed Feed knock off on Amazon which should be arriving in a couple of days.
