Question: Makita RBC251 Trimmer

cehmtx

Please call me regarding replacement of the "bumper" part OR the entire nylon trimmer head assembly. The price differential for my 12yr old trimmer COULD sway my decision to just trash my Makita and purchase a new one.
Thank you. Craig Heller-Bowling Green, KY - 270-842-9620 (office) or 270-991-1128 (cell).

Hello Craig,

The price of the A-15986 Trimmer Head Bumper, as you know is $6.49. The complete Trimmer Head, part number B-60109 is $39.60. The Makita trimmer has always been one of the best ones out there (My opinion). But it looks as if quite a few of the parts are becoming obsolete. So you can decide on what to do.

Hope this helps,

Question: Makita Rbc251 String Trimmer

madzack

My trimmer starts fine but the head doisnt engage fully turns sounds like its grinding any suggestions been a great trimmer for over ten years
WJA
Hello madzack,

Sounds like the gears have finally worn out. You will probably want to replace part number, 6196-30010-06 Gear Case Assembly. They used to sell some of the parts needed for this individually. But it's only available now as an assembly.

Hope this helps,
-WJA
