Overview
Designed as a direct-fit aftermarket replacement, this trimmer head assembly replaces cracked or worn bump-feed heads on compatible string trimmers. The bump knob mechanism is a high-wear component that sees impact on every tap, and replacing the entire head is often more effective than individual part replacement. This assembly comes ready to wind with trimmer line.
Key specifications

Compatibility
This trimmer head is designed for Makita string trimmers as listed above. Confirm the thread size and direction match your trimmer’s drive shaft before ordering.
Installation notes
Remove the old trimmer head by holding the drive shaft and unscrewing the head assembly. Clean the shaft threads before installing the new head. Tighten the new assembly hand-tight plus a quarter turn, then load trimmer line according to the directional arrows on the spool.
Common questions
Q: Will this 195858 trimmer head fit my Makita XRU24Z, and is the 231352-0 compression spring included part of the bump feed assembly?
Yes, this replacement head is made for the Makita XRU24Z and the other listed models: DUR181Z, DUR181RF, and DUR181. The 231352-0 compression spring is part of the bump + feed head assembly, so if your original spring is worn or missing, this setup matches that style.
Q: How do I install this 195858-1 bump feed trimmer head on a DUR181Z without damaging the shaft lock?
Before installing, remove the battery and clean any grass or debris from the gearbox area and spindle threads. Hold the shaft lock only long enough to remove or tighten the head, and thread the new head on carefully by hand first to avoid cross-threading, then snug it down securely.
Q: My Makita DUR181RF head keeps feeding poorly—will replacing it with this 195858 head help, and what maintenance should I do to keep it working right?
If the original bump head is cracked, sticking, or no longer feeding line consistently, replacing it with this 195858-style head is often the correct fix. To keep it feeding properly, use the correct trimmer line size recommended for the DUR181 series, avoid overfilling the spool, and regularly clean out packed grass so the bump mechanism and spring can move freely.
