Most Murray weed eater models use standard household tools, so you likely already have what you need in your garage or workshop. Double-check your owner’s manual for any model-specific requirements before beginning the process.

Safety First: Precautions Before Starting

Working on power tools always carries some risk, especially when dealing with rotating parts and high-speed motors. Taking proper safety precautions protects you from injury and prevents accidental damage to your equipment.

First, always disconnect the spark plug wire (on gas models) or unplug the unit entirely (on electric models) before starting any work. This eliminates the possibility of the tool starting unexpectedly while you are handling it. Never attempt to remove the head while the engine is running or the motor is powered.

Wear safety glasses to protect your eyes from dust, debris, and potential kickback. Heavy-duty gloves improve grip and shield your hands from sharp edges on the head housing or spool. If you are working in a confined space, ensure adequate ventilation to avoid inhaling fumes from fuel or lubricants.

Additionally, place the weed eater on a stable surface such as a workbench or sturdy table. Avoid working on uneven ground or soft surfaces where the tool could tip over. Keep all loose clothing, jewelry, and long hair away from moving parts to prevent entanglement.

Finally, inspect the area around the head for signs of wear, cracks, or loose connections. Addressing these issues early can prevent more serious problems later. Following these safety guidelines ensures a smooth and secure process when learning how to remove head from Murray weed eater safely.

Identifying Your Murray Weed Eater Head Type

Murray manufactures a variety of weed eater models, each equipped with different types of cutting heads. Recognizing which head type your specific model uses is crucial for successful removal. The three most common head styles found on Murray string trimmers are:

1. Bump Feed Head – Features a spring-loaded mechanism activated by tapping the ground to release new line.
2. Automatic Feed Head – Automatically feeds line when the motor is running and the line runs short.
3. Fixed-Line Head – Uses pre-cut lengths of line that must be manually replaced.

To identify your head type, examine the outer casing. Bump feed heads typically have a textured or ribbed surface near the base designed for gripping and striking against the ground. Automatic feed heads often display electronic sensors or buttons labeled “Auto Feed” or “AF.” Fixed-line heads usually lack moving parts and may require removal of screws or clips to access the spool.

Consult your owner’s manual or check the model number printed on the tool’s housing. Entering the full model number into Murray’s official website or customer support portal provides access to detailed specifications, including head compatibility charts and disassembly instructions tailored to your exact unit.

Step-by-Step Guide to Removing the Head

With your tools gathered and safety measures in place, follow these general steps to remove the head from most Murray weed eater models. Note that minor variations may occur depending on your specific model, so refer to your owner’s manual for any deviations.

1. Turn off and disconnect the tool. Remove the spark plug wire or unplug the unit completely to eliminate any chance of accidental startup.
2. Locate the head release mechanism. Depending on your model, this may involve pressing a button, pulling a tab, or unscrewing a retaining nut located at the base of the head.
3. Loosen or remove the retaining screw or nut. Use the appropriate wrench or screwdriver to turn the fastener counterclockwise until it comes free. On some models, you may need to hold the motor shaft steady with a wrench to prevent it from spinning.
4. Remove any protective cover or shroud. Some heads have an outer shell that snaps or screws off to expose the internal spool and line chamber.
5. Pull the head assembly away from the motor shaft. Once all fasteners are removed, gently lift the head straight up and off the threaded end of the motor shaft. Be careful not to drop any internal springs, washers, or spacers.
6. Clean the motor shaft and housing. Wipe away old grease, dirt, and debris using a clean rag. Inspect the shaft threads for damage or corrosion.
7. Prepare for installation of a new head or restringing. If replacing the head, align the new unit with the motor shaft and reinstall according to manufacturer specifications.

Take your time during each step, and do not rush the process. Rushing increases the likelihood of dropping small parts or damaging delicate components. Once the head is successfully removed, you can proceed with cleaning, inspecting, or replacing parts as needed.

Removing Heads from Electric vs. Gas Models

While the basic principles of head removal remain consistent across Murray weed eater models, there are notable differences between electric and gas-powered units. Understanding these distinctions helps you adapt your approach accordingly.

Electric Models

Electric weed eaters generally feature simpler head attachment systems due to their lower torque output compared to gas engines. Most electric models use quick-release buttons or slide-off mechanisms that allow tool-free removal. To remove the head:

• Unplug the unit from the power source.
• Press the release button or slide the locking collar toward the motor housing.
• Twist and pull the head assembly away from the motor shaft.
• Clean the exposed shaft and inspect for wear.

Some higher-end electric models may include additional security features such as locking pins or secondary latches. Always consult your manual to confirm the exact sequence of operations for your model.

Gas Models

Gas-powered Murray weed eaters tend to have more robust head attachments because they generate significantly more rotational force. Removal often requires holding the motor shaft stationary while turning the head retaining nut. Here is how to approach it:

• Drain excess fuel from the tank or move the unit to a well-ventilated outdoor area.
• Remove the air filter cover and air filter to gain better access to the motor housing.
• Insert a wrench through the cooling fins or use a specialized holding tool to prevent the motor shaft from turning.
• Using a socket wrench or open-end wrench, loosen the large hex nut securing the head to the motor shaft.
• Once the nut is fully removed, carefully lift the head off the shaft.

Gas models may also include reverse-threaded nuts on certain configurations, meaning you turn them clockwise to loosen. Check your manual carefully to avoid forcing the wrong direction and stripping the threads.

Working with Bump Feed Heads

Bump feed heads are among the most popular designs used on Murray weed eaters due to their convenience and reliability. These heads automatically advance fresh line when you tap the trimmer on the ground while operating the tool. Removing a bump feed head involves accessing the internal spool and releasing the tension mechanism.

To begin, locate the small indentation or slot on the side or bottom of the head housing. Insert a flathead screwdriver into this opening and apply gentle pressure while rotating the head counterclockwise. Alternatively, some models feature a central release button that must be pressed while simultaneously twisting the head.

Once the head is detached, carefully lift out the inner spool. Pay attention to how the line is threaded through the eyelets and take note of the orientation of any springs, washers, or tensioners. These components play a critical role in ensuring smooth line feed operation after reassembly.

After removing the spool, inspect the line path for blockages or obstructions. Clear away any trapped debris using compressed air or a soft brush. If the line appears frayed or excessively worn, unwind the remaining portion and prepare to restring with fresh line.

Handling Automatic Feed Heads

Automatic feed heads differ from bump feed models in that they sense when the line becomes too short and automatically dispense more line without user intervention. These systems rely on electronic sensors and sometimes a small battery pack integrated into the head assembly.

Removing an automatic feed head typically follows the same initial steps as other head types: disconnect power, locate the release mechanism, and remove fasteners. However, because these heads contain sensitive electronics, extra care should be taken to avoid exposing internal circuits to moisture or static electricity.

When removing the head, avoid touching exposed circuit boards or sensor elements with bare hands. Static discharge can damage delicate microchips and render the auto-feed function inoperable. Instead, handle the head by its outer housing and place it on a non-conductive surface during inspection.

If you plan to replace the entire head unit, verify that the new head is compatible with your model’s voltage and communication protocol. Installing an incompatible head may result in error messages, reduced performance, or complete failure of the auto-feed system.

Common Problems and How to Solve Them

Even experienced users occasionally encounter difficulties when removing the head from a Murray weed eater. Below are some of the most frequently reported issues and practical solutions to help you overcome them.

Head Won’t Budge

If the head refuses to rotate or lift off despite applying moderate pressure, it may be seized due to rust, corrosion, or over-tightened fasteners. Apply a few drops of penetrating oil such as WD-40 around the base of the head and let it sit for 10 to 15 minutes. The oil seeps into tight spaces and breaks down rust bonds, making removal easier.

For gas models, try rocking the head back and forth while pulling upward. This motion helps break loose any seized components. In extreme cases, you may need to use a gear puller or seek assistance from a qualified technician to avoid damaging the motor shaft.

Stripped Threads

Over-tightening the retaining nut or using excessive force can strip the threads on either the motor shaft or the head itself. If the nut spins freely without tightening, the threads are likely damaged. For minor damage, you can attempt to use a thread-locking compound or install a helical thread repair kit.

In severe cases, replacement of the motor shaft or head may be necessary. Contact Murray customer service or an authorized dealer for guidance on sourcing the correct replacement parts.

Missing Springs or Washers

Small components such as compression springs, thrust washers, and spacers are easy to misplace during removal. Before discarding anything, double-check that all parts are accounted for. Refer to your owner’s manual for a parts diagram showing the correct arrangement.

If a component is truly missing, order a replacement kit rather than improvising with substitute materials. Using incorrect parts can lead to improper line tension, premature wear, or catastrophic failure during operation.

Replacement Parts and Compatibility

Murray produces numerous weed eater models spanning multiple generations, each with unique head designs and mounting configurations. When purchasing replacement heads or spools, always verify compatibility with your specific model number.

Start by locating the model number, usually found on a label affixed to the motor housing or along the shaft tube. Enter this number into Murray’s online parts lookup tool to access a comprehensive list of compatible components. Cross-reference part numbers with those listed in your owner’s manual to ensure accuracy.

Popular replacement options include universal-fit heads that accommodate various line diameters and cutting widths. While convenient, these generic alternatives may not offer the same level of precision or durability as OEM (Original Equipment Manufacturer) parts. For critical applications such as commercial landscaping, prioritize genuine Murray components to maintain optimal performance and warranty coverage.

Additionally, consider stocking up on commonly replaced items such as trimmer line, spool assemblies, and retaining nuts. Keeping these supplies on hand minimizes downtime and ensures you are prepared for routine maintenance tasks throughout the growing season.

Maintenance Tips and Best Practices

Beyond simply removing and replacing the head, adopting good maintenance habits extends the life of your Murray weed eater and keeps it performing at peak efficiency. Here are several best practices to incorporate into your regular routine:

• Clean after every use. Remove grass clippings, dirt, and debris from the head housing and motor area immediately after each session. Lingering moisture promotes rust and accelerates wear.
• Inspect the line regularly. Check for fraying, kinking, or uneven wear patterns that indicate the need for replacement. Replace the line before it breaks mid-job to avoid interruptions.
• Lubricate moving parts. Apply a light coat of marine-grade grease to the motor shaft threads and head mounting points to reduce friction and prevent seizing.
• Store properly during off-season. Drain fuel, remove the spark plug, and store the unit in a dry location away from direct sunlight. Consider investing in a protective cover or storage bag.
• Follow recommended line specifications. Use only the diameter and length of trimmer line specified by the manufacturer. Oversized or undersized line can strain the motor and compromise cutting performance.

By integrating these practices into your workflow, you reduce the frequency of major repairs and keep your weed eater operating smoothly season after season.
