How to Buy Used Strimmer Parts

A strimmer is a garden tool that is used to neaten flower beds, finish off lawn mowing or cut down overgrown grass and vegetation that may be too much for a lawn mower to handle. Invented in the early 1970s by a Texan, George Ballas, the first strimmer was made by attaching heavy duty fishing line to a can. Also known as a grass trimmer, more job-specific versions of the strimmer are bush cutters – which are designed to tackle heavy undergrowth – and hedge trimmers – which are vibrating, toothed blades attached to a handle. Strimmers come with three basic power sources: cordless, electric, and petrol, and each type will be appropriate for a certain size of task.

Cordless (battery powered)

Small gardens, restricted areas, flowerbeds, edges, and around trees and shrubs. The battery life limits the scope of work.

Electric (mains powered)

Small to medium gardens within reach of a power socket or within cord length range. The geographical distance from focus point to socket – including the cord length – limits the range of work.

Petrol (fuel powered)

Large areas, heavily overgrown vegetation, broad acreage, substantial maintenance of overgrowth. The weight, noise and fuel emissions will dictate operator fatigue.

The type of power source that will be most appropriate for the task at hand will depend on the level of trimming required. When considering the scope of the job, it will also be necessary to consider the distance from any power sockets or the length of time the job is likely to take. For example, a battery powered strimmer will only be suitable for a short job as the battery will need to be recharged for longer tasks. Not only that, the intensity of the trimming needed will also dictate the type of power source required.

Light -medium

Grass cutting, flower bed edges, around small obstacles.



Grass, weeds, uneven ground.



Large overgrown areas, expansive grounds.


Extending the life of a strimmer, or repairing a non-functioning strimmer, will depend on the power source of the implement.

Cordless Strimmers

Cordless strimmers are powered by rechargeable battery packs. The useful life of the battery pack will depend on how often the strimmer is used and how the battery pack is treated. Batteries generally come in two types:


NiCd batteries can be affected by being intermittently topped up. NiCd batteries should be left to fully discharge before being recharged or the natural life expectancy can be foreshortened.


Lithium-Ion (or Li-Ion)) batteries are designed to produce power with less physical weight. They have little self-discharge and a longer life expectancy than NiCd batteries.

If a battery charger is not functioning properly, it could not only affect the strimmer battery, but also have safety consequences when plugged into a power socket. If the battery charger seems to be malfunctioning, follow the troubleshooting guide below:

Battery charger emitting a strange odour.

Unplug the charger immediately. Do not try to use the charger if there is suspicion that it is malfunctioning.

The cable is split or cracked.

Even if wires are not visible, do not attempt to use the charger as holes in the housing will render the cable no longer waterproof. The cable housing must be undamaged to ensure safe use for the operator.

The battery, charger or plug plastic is damaged.

Deep scratches or cracks in any of the associated parts could be dangerous for the operator. Do not try to recharge the battery or use any section of the charging parts if there is a suspicion of damage.

In general maintenance terms, operators should always adhere to the following advice in order to ensure a fully functioning machine:

Always connect the associated parts in the recommended manner.

Always connect the cable to the charger before plugging the pack into a power socket.

Do not use the battery charger in extreme temperatures.

Consult the manufacturers guide for the appropriate temperatures within which to use the charger. Extreme heat or cold could be damaging to the charger and associated equipment.

Do not leave the battery charger plugged in for extended periods.

Only plug the charger in when actively charging the battery. Continuous charging could damage the ability of the battery to hold charge, and the charger to function properly. Doing otherwise could reduce the natural lifespan of both battery and charger.

Electric Strimmers

Mains powered strimmers have a cord attached permanently to the unit. In order to make sure that the strimmer is in good, safe, working condition, it is wise to regularly check the cord. Look closely at the physical condition of the cord, making sure that it has no cracks, splits or punctures in it and that the wires inside are not visible. A strimmer is designed to be used outside, and a damaged cord will render the strimmer and power source liable to water damage and associated electrical harm to the operator. Do not use an electric strimmer that has any damage to either the cord or the plug as, again, it will render the machine liable to cause harm to the operator.

Petrol Strimmers

Petrol strimmers are available in two styles: two stroke or four stroke engines. Two stroke engines function with one piston, so are smaller and lighter than four stroke strimmer engines. Four stroke strimmer engines use two pistons and, unlike two stroke engines, do not require a mixed fuel source. Maintaining either style of petrol powered strimmer requires regular attention to ensure that the unit does not suffer unnecessary impediment to its lifespan:

Inspect before use.

Inspect all fasteners to ensure they are in place and tightened securely. Check the strimmer fuel tank for leaks. If any damage is observed, do not use the strimmer before repair.

Check for cracks chips or damage.

Check the strimmer head for cracks, chips or any other damage. Ensure that all parts are correctly and securely installed.

Check the air filter.

Check that the filter has no impediment to air flow. If necessary, clean it prior to starting the engine.

Check the line.

Make sure only the manufacturer approved size of line is installed.

Check the housing.

Ensure the drive shaft housing is properly supported to prevent the line from coming into contact with a damaging object.

Spare Parts

Although it is possible to buy new parts for any damaged strimmer, it is also advisable to consider buying a full unit for parts. By doing so, it allows an operator to have access to a full range of associated hardware to ensure continuous use. Used parts will also be less costly than new parts, although some mechanical ability will be vital to fully realise any savings as repairs will necessarily need to be made by the operator. Some of the most regularly replaced parts are:

Strimmer drive belt

A type of flat rubber drive belt that is used to turn multiple accessories on the front of any engine. It is also called a ‘serpentine belt’ due to the sinuous and snake-like way it feeds through the machine. In a strimmer, it allows the rotation of the line.

Spark plug

A spark plug is used in an internal combustion engine to ignite the fuel in order to cause motion. To replace a spark plug in a strimmer simply pop the cover, use a 3/4in socket to remove the old spark plug, insert the new socket and tighten in place.

How to Buy Used Strimmer Parts on eBay

To buy a strimmer, first go to the eBay homepage, opening the All Categories tab, then click on the link for Home & Garden.Next choose Garden, followed by Power Tools and Equipment from the drop down menu. Then click on Strimmers in the left hand menu. For Parts or Not Working will be part of the filter options in the left hand side, so choose that option to bring up available item listings or click Used in the condition filter to consider any other items for parts. Alternatively, use the search bar at the top of any eBay page. For example, to find a strimmer spool cover, key in “strimmer spool cover”.


A strimmer can be used for light finishing of lawn edges and flower beds or for more strenuous maintenance of overgrown grass and vegetation. Strimmers come with a choice of three power sources (electric, battery or mains powered) and these sources will dictate how suitable each type may be for the planned task. Extending the life of a strimmer, or repairing a non-functioning strimmer, will depend on the power source of the implement and the appropriate maintenance undertaken by the operator. Regular attention should be taken to ensure that any unit does not suffer unnecessary impediment to its lifespan. By buying an old or non-functioning strimmer, an operator will have access to a full range of associated hardware to ensure continuous use. Used parts will generally be less expensive than new parts, although some mechanical ability will be necessary in order that an operator may maintain the strimmer in such a manner.
