Einhell 3405660 replacement lawn mower blade, 51 cm metal rotary blade

Choosing a replacement blade is about keeping your existing mower ready for the next cut, rather than changing your whole set-up. The Einhell 3405660 is a metal rotary blade with a 51 cm blade length. It is designed for specified Einhell petrol mower models, making compatibility the key point when choosing it.

Key takeaways

This replacement blade is suitable for the Einhell GC-PM 51/2 S HW, GC-PM 51/2 HW SE and GC-PM 51/2 S HW B&S petrol lawn mowers. Its 51 cm length gives you a clear measurement to match against the blade required for your mower, while the metal construction and rotary style identify the type of replacement part. The product is supplied as one replacement blade, so it is a straightforward choice when you are looking for this particular part rather than a mower accessory with a different function.

For a compatible mower, choosing the specified replacement blade offers a direct way to renew the cutting component while keeping the existing machine in use. If you are comparing this with buying a complete mower, the blade is the more targeted option when your current mower is one of the named models and you need its replacement cutting part.

Size & fit

The blade measures 51 cm in length and is intended for three Einhell petrol mower models: GC-PM 51/2 S HW, GC-PM 51/2 HW SE and GC-PM 51/2 S HW B&S. Match the model name on your mower with this list before selecting the blade. This helps ensure that the replacement is chosen for the stated mower family, rather than relying on blade length alone. The product’s model number is 3405660, useful when identifying this specific Einhell spare part.

Everyday use

A replacement blade is relevant when maintaining a compatible petrol mower and preparing it for regular lawn cutting. For example, if you are replacing the cutting blade on one of the listed GC-PM models, this part gives you a defined 51 cm size and the rotary format associated with the mower. Its metal construction makes it a practical match for buyers seeking the specified replacement component, rather than a general-purpose lawn care accessory.

When planning a replacement, identify your mower by its model name and use the blade’s 51 cm length as an additional reference. The fit information is particularly useful if you are comparing spare parts that look similar: the named mower compatibility and product number provide a more precise way to select this blade. Follow the mower’s instructions when carrying out fitting or maintenance, and make sure the mower is safely prepared before handling the blade.
