Knives are key parts in lawn mowers, responsible for effectively cutting grass or other vegetation. There are many types of knives, adapted to different types of mowers and working conditions. Cutting knives used in most lawn mowers for cutting grass. They may have different lengths and shapes, depending on the mower model. Flail knives used in flail (mulching) mowers. They have a special shape that makes it easier to chop the mown grass into small fragments, which are then spread on the soil as a natural fertilizer.

Nuts are one of the basic elements of assembly mechanisms that play a key role in many mechanical devices, including lawn mowers. Nuts are used to connect and fasten various elements in mowers. They can be used to attach cutting knives, covers, wheels, and other mechanical components.

Screws are an indispensable structural element in many machines, including lawn mowers. Bolts are used to connect various mechanical elements in mowers. They can be used to attach cutting knives, covers, drive elements and other structural components.

Bearings are key components in lawn mower mechanisms that allow the machine's components to rotate with minimal friction. Bearings are components that enable the rotation of shafts, rollers and other moving parts in lawn mowers. Their main function is to reduce friction and mechanical wear by ensuring smooth movement.

The Pulley is a key component in lawn mowers that transfers energy from one shaft to another via a drive belt. A pulley is used to transfer power from one shaft to another using a drive belt. It is an element that allows the transfer of mechanical energy between various parts of the mower, such as the engine, drive shaft or other drive elements.

A conical wedge, also called an arch wedge, is a mechanical element used to connect two parts, especially in cases requiring a strong and durable connection. A conical wedge is used to provide a permanent connection between two elements by forcing them together by pressing the wedge into the gap between them. The tapered key is most commonly used to secure implements to power take-off shafts (PTOs), but can also be used in other applications where a strong connection is required.

A bevel gear, also called a bevel gear or a bevel gear, is a type of mechanism used to change the direction and rotational speed of power transmission between two shafts that are at an angle to each other. The bevel gear allows you to transmit power and change the direction of rotation between two shafts that are set at different angles. It is used where it is required to transmit torque in planes other than straight ones, for example in lawn mowers, agricultural machines, mechanical transmissions, or in various industrial devices.
