Understanding Your Murray Weed Eater

Model Identification

Murray has produced a range of string trimmers over the years, from the lightweight 20‑volt cordless units to the heavier gas‑powered 25‑cc models. The first step in any repair is to locate the model number, usually stamped on a label near the motor housing or on the shaft. Knowing the exact model lets you purchase the correct spool size, line diameter, and any proprietary parts. Most Murray trimmers use a 0.080‑inch (2.0 mm) or 0.095‑inch (2.4 mm) round line, but some newer heads accept a 0.105‑inch (2.7 mm) square line for tougher weeds.

Types of Trimmer Heads

There are three common head designs on Murray equipment: the fixed‑spool head, the bump‑feed head, and the rapid‑reload head. A fixed‑spool head requires manual winding each time you replace line. A bump‑feed head advances line automatically when you tap the head on the ground. The rapid‑reload head, often marketed as “General Murray Reload,” uses a pre‑wound cartridge that snaps into place, eliminating the need for manual winding. Identifying which head you have determines the exact restringing procedure you will follow.

Tools and Materials Needed

Gather the following items before you begin: a replacement trimmer line of the correct diameter and length (typically 15–20 feet for a standard spool), a pair of heavy‑duty scissors or a line cutter, a clean rag, a small brush for debris removal, and a pair of work gloves to protect your hands from sharp edges. If your model uses a bump‑feed head, you may also need a small flat‑head screwdriver to release the spool retainer. For gas‑powered units, have a spark‑plug wrench handy in case you need to disconnect the spark plug for added safety. Keep the owner’s manual nearby for model‑specific torque specifications or diagrams.

Safety Precautions

Before any work on a power tool, disconnect the energy source. For electric models, unplug the cord or remove the battery pack. For gas models, remove the spark‑plug wire and let the engine cool completely. Wear safety glasses to shield your eyes from flying debris, and use hearing protection if you will be running the trimmer after reassembly. Never attempt to restring the head while the engine is running or the motor is energized. Keep the work area well‑lit and free of flammable materials, especially when handling gasoline‑powered equipment.

Step‑by‑Step Guide to Restring a Murray Weed Eater

1. Remove the Spool

Locate the spool release button or latch on the trimmer head. Press or slide it according to the manufacturer’s direction, then pull the spool straight out. On bump‑feed heads you may need to unscrew a retaining cap with a screwdriver before the spool can be lifted. Set the spool on a clean surface.

2. Clean the Head

Use the brush and rag to remove grass clippings, dirt, and old line fragments from the head housing and the spool cavity. Debris can cause the new line to bind or feed unevenly. Inspect the eyelets for wear; if they are cracked or excessively grooved, consider replacing the head assembly.

3. Measure and Cut the New Line

Consult the manual for the recommended line length. A typical spool holds about 15 feet of 0.080‑inch line. Cut two equal lengths if your head uses a dual‑line configuration, or a single length for a single‑line head. Cutting the line slightly longer (by 6–12 inches) gives you room to thread the ends without stretching the material.

4. Load the Line onto the Spool

Find the anchoring hole or notch on the spool. Insert one end of the line and wind it in the direction indicated by the arrow on the spool (usually clockwise). Keep the windings tight and even, laying each turn next to the previous one without overlapping. Leave about 6 inches of line protruding from the eyelet for the initial feed. Repeat for the second line if applicable, using the opposite winding direction if the spool has two separate chambers.

5. Reassemble and Test

Place the spool back into the head, ensuring the protruding line ends feed through the eyelets. Snap or screw the retaining cap back in place. Reconnect the power source, start the trimmer, and gently tap the head on the ground (for bump‑feed) or pull the trigger to advance line. Verify that the line feeds smoothly and cuts cleanly. Adjust tension if the line stalls or snaps.

General Murray Reload: Universal Spool vs. Brand‑Specific

Many users wonder whether a universal “General Murray Reload” cartridge can replace the original spool. The table below compares key attributes to help you decide.

If you value speed and convenience, the universal cartridge is a solid choice. For heavy‑duty commercial use where line geometry matters, the brand‑specific spool often delivers a cleaner cut and longer intervals between reloads.

Tips for Longer Line Life

• Use the correct line diameter; oversized line stresses the motor and wears the eyelets faster.
• Store spare line in a cool, dry place to prevent UV degradation.
• Trim grass at the recommended height; cutting too low forces the line into hard soil and rocks.
• Periodically lubricate the spool shaft with a light silicone spray to reduce friction.
• Avoid running the trimmer at full throttle continuously; pulse the trigger to let the line cool.

Common Mistakes and How to Avoid Them

• Over‑winding the spool: Packing too much line causes binding. Follow the maximum fill line marked on the spool.
• Wrong winding direction: Winding opposite the arrow makes the line feed backward. Always match the arrow.
• Using damaged line: Frayed or kinked line snaps under load. Inspect each length before loading.
• Neglecting eyelet wear: Worn eyelets shred line. Replace the head if grooves exceed 1 mm depth.
• Skipping safety disconnect: Accidental start‑up can cause serious injury. Always disconnect power first.

Troubleshooting Common Issues

If the line does not advance, first verify that the spool rotates freely. A seized spool often results from debris or a bent shaft. Clean the shaft and apply a drop of light oil. If the line feeds but breaks immediately, check that the line diameter matches the head specification and that the eyelets are not sharp. For a bump‑feed head that fails to release line, ensure the bump knob moves freely and the internal spring is intact. On rapid‑reload cartridges, a misaligned cartridge can prevent the line from seating; remove and re‑insert until you hear a firm click.

Maintenance Schedule

Adhering to a simple schedule extends the life of both the trimmer and the cutting line. After each use, wipe the head and inspect the line for wear. Every 10 hours of operation, remove the spool, clean the cavity, and check the eyelets. Replace the line whenever it falls below 2 inches of usable length. Once per season, inspect the drive shaft, air filter (on gas models), and spark plug. Lubricate the spool shaft and verify that all fasteners are tight. Keeping a log of hours and service dates helps you anticipate parts replacement before a failure occurs.

Frequently Asked Questions

How often should I restring my Murray weed eater?

Restring whenever the visible line length drops below about 2 inches or when cutting performance noticeably declines. For typical residential use, this occurs every 5–10 hours of run time.

Can I use any brand of trimmer line?

You can use any line that matches the diameter and shape specified for your model. Using a different diameter may cause feeding problems or excess motor strain.

What is the difference between round and square line?

Round line is quieter and lasts longer on light grass. Square line has sharper edges that cut thicker weeds more aggressively but wears faster and can be louder.

Why does my line keep tangling inside the head?

Tangling usually results from over‑filling the spool, winding in the wrong direction, or using line that is too stiff for the head’s feed mechanism. Follow the fill line and winding arrow precisely.

Is the General Murray Reload cartridge worth the extra cost?

If you value quick reloads and minimal downtime, the cartridge pays for itself in saved labor. For occasional users, manual winding with bulk line is more economical.

Conclusion

Restringing a Murray weed eater is a straightforward task that pays dividends in cutting performance and equipment longevity. By identifying your model, gathering the right tools, observing safety protocols, and following the step‑by‑step winding procedure, you can restore your trimmer to like‑new condition in minutes. Choosing between a universal reload cartridge and a brand‑specific spool depends on your balance of convenience versus cost, and the comparison table above should guide that decision. Regular cleaning, proper line selection, and adherence to a simple maintenance schedule will keep the line feeding smoothly and reduce the frequency of reloads. With these practices in place, you’ll spend less time wrestling with tangled line and more time enjoying a well‑trimmed lawn.
