Mower types
The cutting mechanism in a mower may be one of several different designs:
Sickle mower
![Eicher Mähbalken](https://upload.wikimedia.org/wikipedia/commons/9/9b/Eicher_M%C3%A4hbalken.jpg)
''Sickle mowers'', also called ''reciprocating mowers'', ''bar mowers'', ''sickle-bar mowers'', or ''finger-bar mowers'', have a long (typically six to seven and a half feet) bar on which are mounted fingers with stationary guardplates. In a channel on the bar there is a reciprocating sickle with very sharp sickle sections (triangular blades). The sickle bar is driven back and forth along the channel. The grass, or other plant matter, is cut between the sharp edges of the sickle sections and the finger-plates (this action can be likened to an electric hair clipper).
The bar rides on the ground, supported on a skid at the inner end, and it can be tilted to adjust the height of the cut. A spring-loaded board at the outer end of the bar guides the cut hay away from the uncut hay. The so-formed channel, between cut and uncut material, allows the mower skid to ride in the channel and cut only uncut grass cleanly on the next swath. These were the first successful horse-drawn mowers on farms and the general principles still guide the design of modern mowers.
Rotary mower
Rotary mowers, also called ''drum mowers'', have a rapidly rotating bar, or disks mounted on a bar, with sharpened edges that cut the crop. When these mowers are tractor-mounted they are easily capable of mowing grass at up to 10 miles per hour (16 km/h) in optimal conditions. Some models are designed to be mounted in double and triple sets on a tractor, one in the front and one at each side, thus able to cut up to 20 foot (6 metre) swaths.
In rough cutting conditions, the blades attached to the disks are swivelled to absorb blows from obstructions. Mostly these are rear-mounted units and in some countries are called ''scrub cutters''. Self-powered mowers of this type are used for rougher grass in gardening and other land maintenance.
Reel mower
![Rusted reel mower](https://upload.wikimedia.org/wikipedia/commons/6/63/Rusted_reel_mower.JPG)
''Reel mowers'', also called ''cylinder mowers'' (familiar as the hand-pushed or self-powered cylinder
lawn mower), have a horizontally rotating cylindrical reel composed of helical blades, each of which in turn runs past a horizontal cutter-bar, producing a continuous scissor action. The bar is held at an adjustable level just above the ground and the reel runs at a speed dependent on the forward movement speed of the machine, driven by wheels running on the ground (or in self-powered applications by a motor). The cut grass may be gathered in a collection bin.
This type of mower is used to produce consistently short and even grass on bowling greens, lawns, parks and sports grounds. When pulled by a tractor (or formerly by a horse), these mowers are often ganged into sets of three, five or more, to form a ''gang mower''. A well-designed reel mower can cut quite tangled and thick tall grass, but this type works best on fairly short, upright vegetation, as taller vegetation tends to be rolled flat rather than cut.
Home reel mowers have certain benefits over motor-powered mowers as they are quieter and not dependent on any extra form of power besides the person doing the mowing. This is useful not only to lessen dependence on other types of power which may have availability issues, but also lessens the impact on the environment.
Flail mower
Flail mowers have a number of small blades on the end of chains attached to a horizontal axis. The cutting is carried out by the ax-like heads striking the grass at speed. These types are used on rough ground, where the blades may frequently be fouled by other objects, or on tougher vegetation than grass, such as brush (scrub). Due to the length of the chains and the higher weight of the blades, they are better at cutting thick brush than other mowers, because of the relatively high inertia of the blades. In some types the cut material may be gathered in a collection bin. As a boom mower (see above), a flail mower may be used in an upright position for trimming the sides of hedges, when it is often called a ''hedge-cutter''.
Drum mower
![Fella Radon Drum Mower](https://upload.wikimedia.org/wikipedia/commons/7/70/Fella_Radon_Drum_Mower.jpg)
Drum mowers are known for their simplicity and robustness. They consist of two large drums, each containing three to four spinning blades that chop down the grass or crop as they move over it. This straightforward design makes them easier to maintain, often leading to a longer lifespan.
Drum mowers are particularly effective in tall and dense grass, where their powerful cutting action can make quick work of the task. However, they may struggle on uneven terrain, and their cutting speed may be slower compared to more modern designs. Their affordability and sturdy build make them an attractive option for smaller farms or those working on a budget.
