Lawn Mower Clutch Replacement Part for 139 140 150 GX35 40-5 430 Brush Cutter and Two-Stroke Four-Stroke Engine Models Universal Fit 183g
Lawn Mower Clutch for 139 140 150 GX35 40-5 and 430 Brush Cutter Models
This lawn mower clutch is a replacement component for a range of brush cutter and lawn mower engines, including the 139, 140, 150, GX35, 40-5 and 430 model numbers. It is listed as a universal clutch for those fitments and is intended for both two-stroke and four-stroke machines where the corresponding model applies. The clutch sits between the engine and the cutting attachment, engaging the drive so the head turns when the engine speeds up. If your machine has lost drive, is slipping under load, or the cutting head no longer spins as it should, the clutch is a sensible part to inspect. This listing provides one clutch unit, weighing approximately 183g, in the colour option shown. Because the source information is limited, the exact spline count, drum size and spring rating are not stated, so it is important to compare the part with your original unit or model code before ordering. The details below set out what is confirmed and where the data ends.
Features and Construction
The information available for this clutch covers its fitment list, its weight and its role in the drive system. It is described as suitable for the models named above and for both two-stroke and four-stroke engines within that range. No material specification, hardness rating or manufacturing standard is given in the source text, so those points are left out rather than guessed.
Material and Build
The source text does not name the materials used in this clutch. It is presented simply as a mechanical replacement part for the listed model numbers. For that reason, no claims can be made about wear resistance, heat treatment or coating. What can be confirmed is that it is a clutch assembly intended to replace the corresponding unit on 139, 140, 150, GX35, 40-5 and 430 machines. When fitting, handle it as you would any small engine clutch and keep it clean and dry before installation.
Size and Practical Fit
The only measurable figure provided is an approximate product weight of 183g. That weight applies to the clutch itself and is close to the mass of a typical unit in this class, though no comparison figures are supplied. There are no stated dimensions for the outer diameter, centre bore, shoe width or spring height, so fitment should be checked against your original part. The clutch is listed as universal for the model numbers shown, which gives a starting point for matching, but the model code on your machine remains the most reliable reference.
Uses and Placement
A clutch of this type is used where a petrol engine drives a cutting head through a centrifugal engagement mechanism. On brush cutters and lawn mowers, it allows the head to stay still at idle and then engage as engine speed rises. This replacement is aimed at the models listed in the source text and is suited to both two-stroke and four-stroke versions within that group.
Event or Professional Use
For grounds maintenance, verge cutting and similar work, a worn clutch can cause the cutting head to slip or stop turning altogether. This part is intended to restore that drive on the stated models. It is supplied as a single unit, so it suits a repair rather than a bulk order. If you run several machines with the same engine code, check each one against the fitment list before ordering. No professional certification or commercial-use rating is claimed in the source text.
Everyday Home Use
For home gardeners using a brush cutter or lawn mower with one of the listed engines, this clutch offers a way to replace a failed unit without changing the whole machine. It fits the 139, 140, 150, GX35, 40-5 and 430 fitments as stated. The 183g weight makes it manageable during a DIY repair. As with any engine part, take care with fuel and ignition systems before starting work, and refit the cutting guard and safety equipment afterwards.
Benefits and Buying Value
The main value of this listing is a direct replacement clutch for a spread of common small engine model numbers, supplied as one unit. It avoids the need to replace an otherwise serviceable machine when only the clutch has failed. Because the source data is limited, the benefits are practical rather than performance-based.
Reuse and Low Maintenance
Replacing the clutch allows the existing brush cutter or lawn mower to be put back into use, provided the rest of the machine is in working order. This keeps the original tool in service rather than sending it for scrap. No maintenance interval, service life or lubrication schedule is stated in the source text, so no such guidance is offered here. Keep the part clean before fitting and store it in a dry place if it is not installed straight away.
Why Choose This Product
This clutch is worth considering when your machine matches one of the listed models and the existing clutch has stopped engaging the cutting head. It covers 139, 140, 150, GX35, 40-5 and 430 fitments and works with both two-stroke and four-stroke engines in that group. The approximate 183g weight is the only confirmed physical figure. If your model is not on the list, or you need exact dimensions, the source text does not provide enough detail to confirm fitment, so check against your original part first.
