The trimmer head is where all the action happens on your Green Machine string trimmer. When the bump head wears out, won't feed line, or gets jammed, a replacement trimmer head assembly gets you cutting again fast. OEM Green Machine trimmer heads are engineered to feed.065" line smoothly and handle the RPM your trimmer delivers.
If you're seeing line tangles, inconsistent feeding, or the head won't bump out fresh line, the spool or internal feed mechanism inside the head has failed. Rather than troubleshoot individual parts, an OEM trimmer head replacement is the right call — it comes ready to load and attach.
Most Green Machine string trimmers use.065" round trimmer line. Always confirm your exact model number — a few specialty models may use.080" or twisted line. Load the correct diameter; oversized line won't feed properly and undersized line breaks constantly. You'll find the line spec on the trimmer head housing or in your owner's manual.
A jammed or non-feeding trimmer head usually means the internal spool has worn grooves, the feed arm is bent, or the spring mechanism has lost tension. Try clearing any wrapped line first, but if the head still won't feed smoothly after cleaning, the spool assembly inside has failed. An OEM Green Machine trimmer head replacement solves this — you get a fresh spool, working feed mechanism, and reliable line advancement.
Most Green Machine trimmer heads are designed as sealed, integrated units. While you can sometimes buy individual spools, the labor to disassemble and reassemble often exceeds the cost of a new head. An OEM replacement head is simpler, faster, and comes with a help ensure. Enter your Green Machine model number to find the exact OEM trimmer head assembly.
Bump heads load differently than fixed-spool heads. For a typical Green Machine bump head: (1) Remove the head cover by twisting counter-clockwise. (2) Wind.065" line around the spool in the direction marked on the housing. (3) Leave a short tail for the feed arm to grab. (4) Screw the cover back on hand-tight. (5) Bump the head on the ground to advance line. Always check your model's manual for specific loading steps — loading direction varies by design.
