Makita B-05119 Bump-and-Feed Trimmer Head, Large-Capacity M10 x 1.25 LH — Preloaded .095" Line, Heavy-Duty Feed

The Makita B-05119 is a large-capacity bump-and-feed trimmer head that holds more line, loads quickly, and fits commercial M10 x 1.25 arbor string trimmers.

Designed for demanding trimming jobs, this Makita replacement head increases run time between reloads and simplifies line changes with a secure spring lock spool. It ships with .095" round line installed and supports a range of line diameters so you can choose heavier or lighter cord depending on vegetation and cutting needs. The robust bump-feed mechanism advances line on demand, making it practical for landscapers and homeowners who need a fast, reliable feed system.

How does the large capacity improve productivity?

More line on the spool means fewer stops to refuel, which speeds through large properties or long commercial jobs. The increased capacity reduces downtime and keeps the trimmer cutting longer between reloads.

• Accepts up to 30 ft of .080" line for extended runtime
• Supports heavier lines (.095" .105" .130") for tougher vegetation
• Less frequent reloading on long jobs saves time

What are the compatibility and fit details?

The head uses an M10 x 1.25 left-hand threaded arbor, compatible with many Makita commercial stroke-engine models and Delmar units that share the same mounting specification. Confirm your trimmer’s spindle thread and direction before ordering to ensure a proper fit.

• M10 x 1.25 LH arbor included for straightforward installation
• Works with Makita and Delmar commercial-duty string trimmers
• Ships preloaded with .095" round cutting line for immediate use

How easy is it to load and feed replacement line?

The spring-lock spool holds the line securely during assembly and keeps the spool seated while you wind new cord. The bump-and-feed action advances line without disassembly, so you only need to tap the head on the ground to release fresh cutting length.

• Spring lock secures spool for easier winding and installation
• Bump-and-feed mechanism advances line on demand while trimming
• Quick-loading design minimizes time spent on maintenance

Which line sizes can I use and why choose one over another?

This trimmer head accepts several diameters so you can match line thickness to the task: lighter gauges for ornamental grass and heavier gauges for thick brush and weeds. Choose the heaviest line your trimmer supports for the toughest cutting; lighter line gives higher speed and less strain on the engine.

• Up to 30 ft of .080" for long runtime and light trimming
• 20 ft of .095" or .105" for general-purpose cutting and durability
• 10 ft of .130" for heavy brush where maximum cutting strength is needed

Who is this for: The Makita B-05119 suits professional landscapers, rental fleet operators, and homeowners with large yards who need a rugged, high-capacity trimmer head. It’s ideal when you want fewer reloads, faster line advancement, and compatibility with M10 x 1.25 left-hand threaded commercial trimmers. Choose this head if you value durable construction, flexible line-size options, and a reliable bump-and-feed system for extended trimming sessions.
