Purchase criteria

Compatibility

The most important criterion when buying a mulching knife is its compatibility with the lawn mower or the mower. Brush cutter. This means you should choose a model that matches the make, serial number and type of your lawnmower. Read the product description carefully, as the corresponding lawnmowers are often listed here. Many lawnmower brands offer original knives, but you can also purchase matching (and cheaper) replicas. An unsuitable mulching knife cannot be installed and therefore cannot be used.

Dimensions

However, the lawnmower models that match the mulching knife are not always specified, especially when it comes to all-purpose replica mulching knives. Here you have to compare the dimensions of the knife, whereby the knife length and width are particularly important. Both sizes cannot be flexibly adjusted with universal knives and must therefore fit your lawnmower exactly.

Hole diameter

In contrast to this, the size of the holes on many universal knives - such as the central hole and the outer holes - can be adjusted, for example using special attachments to reduce the size of the hole. These are often, but not always, supplied with universal mulching knives and are often indispensable. If flexible adjustment is not possible, the diameter of the three holes should fit your lawnmower model exactly.

Knife type

There are different types of mulching knives that must of course fit your lawnmower. Basically, mowing knives and mulching knives are two fundamentally different things that are used for different tasks. You cannot cut the lawn with a mulching knife, only chop the grass. Therefore, you either need a special mulching knife or a combination knife, which can both cut and chop. Wing-shaped mulching knives are ideal for Mulching of short, dry grass. If, on the other hand, your lawn has grown taller and / or is rather damp, other (longer) blades are advisable.

material

So that the mulching knife lasts a long time and does not give up the ghost the first time you use it, you should pay attention to high-quality material. If possible, choose products without any plastic parts, instead a high-quality mulching knife is always made of stainless steel, if possible coated. Also keep in mind that the knives come into contact with moisture and can therefore rust quickly: an appropriate coating and proper care prevent this.
