A mower is a person or machine that cuts (mows) grass or other plants that grow on the ground. Usually mowing is distinguished from reaping, which uses similar implements, but is the traditional term for harvesting grain crops, e.g. with reapers and combines.

Contents

A smaller mower used for lawns and sports grounds (playing fields) is called a lawn mower or grounds mower, which is often self-powered, or may also be small enough to be pushed by the operator. Grounds mowers have reel or rotary cutters. Larger mowers or mower-conditioners are mainly used to cut grass (or other crops) for hay or silage and often place the cut material into rows, which are referred to as windrows . Swathers (or windrowers) are also used to cut grass (and grain crops). Prior to the invention and adoption of mechanized mowers, (and today in places where use a mower is impractical or uneconomical), grass and grain crops were cut by hand using scythes or sickles.

Larger mowers are usually ganged (equipped with a number or gang of similar cutting units), so they can adapt individually to ground contours. They may be powered and drawn by a tractor or draft animals. The cutting units can be mounted underneath the tractor between the front and rear wheels, mounted on the back with a three-point hitch or pulled behind the tractor as a trailer. There are also dedicated self-propelled cutting machines, which often have the mower units mounted at the front and sides for easy visibility by the driver. Boom or side-arm mowers are mounted on long hydraulic arms, similar to a backhoe arm, which allows the tractor to mow steep banks or around objects while remaining on a safer surface.

Mower types

The cutting mechanism in a mower may be one of several different designs:

Sickle mower

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

Reel mowers, also called cylinder mowers [2] (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. [3]

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

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. [4]

<span class="mw-page-title-main">Tractor</span> Engineering vehicle specifically designed to deliver a high tractive effort

A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.

<span class="mw-page-title-main">Scythe</span> Agricultural reaping hand tool

A scythe is an agricultural hand tool for mowing grass or harvesting crops. It is historically used to cut down or reap edible grains, before the process of threshing. The scythe has been largely replaced by horse-drawn and then tractor machinery, but is still used in some areas of Europe and Asia. Reapers are bladed machines that automate the cutting of the scythe, and sometimes subsequent steps in preparing the grain or the straw or hay.

<span class="mw-page-title-main">Lawn mower</span> Grass cutting device

A lawn mower is a device utilizing one or more revolving blades to cut a grass surface to an even height. The height of the cut grass may be fixed by the design of the mower but generally is adjustable by the operator, typically by a single master lever or by a mechanism on each of the machine's wheels. The blades may be powered by manual force, with wheels mechanically connected to the cutting blades so that the blades spin when the mower is pushed forward, or the machine may have a battery-powered or plug-in electric motor. The most common self-contained power source for lawn mowers is a small internal combustion engine. Smaller mowers often lack any form of self-propulsion, requiring human power to move over a surface; "walk-behind" mowers are self-propelled, requiring a human only to walk behind and guide them. Larger lawn mowers are usually either self-propelled "walk-behind" types or, more often, are "ride-on" mowers that the operator can sit on and control. A robotic lawn mower is designed to operate either entirely on its own or less commonly by an operator on a remote control.

A reaper is a farm implement or person that reaps crops at harvest when they are ripe. Usually the crop involved is a cereal grass. The first documented reaping machines were Gallic reapers that were used in Roman times in what would become modern-day France. The Gallic reaper involved a comb which collected the heads, with an operator knocking the grain into a box for later threshing.

A string trimmer, also known by the portmanteau strimmer and the trademarks Weedwacker, Weed Eater and Whipper Snipper, is a garden tool for cutting grass, small weeds, and groundcover. It uses a whirling monofilament line instead of a blade, which protrudes from a rotating spindle at the end of a long shaft topped by a gasoline engine or electric motor.

<span class="mw-page-title-main">Conditioner (farming)</span>

A conditioner is a farm implement that crimps and crushes newly cut hay to promote faster and more even drying. Drying the hay efficiently is most important for first cutting of the hay crop, which consists of coarse stalks that take a longer period of time to draw out moisture than finer-textured hays, such as second and subsequent cuttings.

<span class="mw-page-title-main">Brush hog</span> Powered vegetation cutter

A bush hog or "brush hog" is a type of rotary mower. Typically these mowers attach to the back of a farm tractor using the three-point hitch and are driven via the power take-off (PTO). It has blades that are not rigidly attached to the drive like a lawnmower blade, but are on hinges so if the blade hits a rock or stump, it bounces backward and inward, and then centrifugal force makes it go outwards again.

<span class="mw-page-title-main">Flail mower</span> Powered vegetation cutter

A flail mower is a type of powered garden/agricultural equipment which is used to deal with heavier grass/scrub which a normal lawn mower could not cope with. Some smaller models are self-powered, but many are PTO driven implements, which can attach to the three-point hitches found on the rear of most tractors. This type of mower is best used to provide a rough cut to long grass and even brambles in locations such as roadsides, where contact with loose debris may be possible.

<span class="mw-page-title-main">Swathe</span>

A swathe is the strip of cut crop made by a scythe or a mowing-machine. A mower with a scythe cuts a swathe along the mowing-edge leaving the uncut grass to the right and the cut grass laid in a windrow to the left on the previously mown land. The swathe width depends on the blade length, the nature of the crop, and the mower, but for grass is usually about 1.5 metres (4.9 ft) wide. When mowing in a team the mowers start at the edge of a meadow in a staggered line, then proceed clockwise, leaving a series of swathes with windrows and finishing in the middle.

The GE Elec-Trak was the first commercially produced all-electric garden tractor, made mostly between 1969 and 1975 at GE's Outdoor Power Equipment Operation under Bruce R. Laumeister. The previous work of Laumeister at GE on the experimental Delta electric car that debuted in 1968 helped pave the way for the production of the Elec-Trak. Despite the limited production and availability of the electric tractors, many Elec-Traks are still in use today and have a cult following among tractor and electric vehicle enthusiasts. They are an archetypal or seminal design that has influenced all later electric tractors.
