harrow, farm implement, consisting of a wooden or metal framework bearing metal disks, teeth, or sharp projecting points, called tines, which is dragged over plowed land to pulverize the clods of earth and level the soil. Harrows are also used to uproot weeds, aerate the soil, and cover seeds. Primitive harrows were twiggy branches drawn over the soil to smooth it; in India a ladderlike device of bamboo is still used. In modern large-scale farming, harrows are of varied types. Some are simply dragged behind a tractor or draft animal; some are suspended on wheels; many have levers to adjust the depth of the cut. There may be one or more gangs (sets) of cutting parts per harrow, and one or more harrows may be drawn at a time. In disk harrows, which next to the plow are the most widely used tillage implements, the saucer-shaped disks are set at angles to the line of pull for maximum pulverization. Spike-tooth harrows have rigid teeth, and spring-tooth harrows have curved tines that adjust to obstacles. The rotary crossharrow has power-driven rotating toothed disks; another type of harrow slices through topsoil and vegetation with curved knives. In general, the harrow is similar to the cultivator, except that it penetrates the soil to a lesser depth.

Harrow is a town in the London Borough of Harrow, North West London. It is a suburb situated 12.2 miles (16.4 km) west northwest of Charing Cross. It is one of the major metropolitan centres identified in the London Plan. Harrow is widely known for Harrow School, attended by Winston Churchill and Indian Prime Minister Nehru, however Harrow County School also had a tradition of noted staff and pupils, e.g. Sir Paul Nurse, Sir Nigel Sheinwald, Michael Portillo, Clive Anderson and Geoffrey Perkins. Harrow is home to a large University of Westminster campus near Northwick Park Hospital (although both these landmarks actually lie within the London Borough of Brent). Harrow was a municipal borough of Middlesex before its inclusion in Greater London in 1965.


Its name came from Old English hearg = "(heathen) temple", which was probably on the hill of Harrow, where St. Mary's Church stands today.

Present day

Harrow features a moderately large shopping area in the town centre. The main shopping district is located near Harrow-on-the-Hill tube station and Harrow Bus Station, and has two shopping centres. The St. Ann's Shopping Centre (formerly the site of Heathfield High School for Girls), opened by Princess Diana in 1987, is the older of the two and contains an extensive food court. St. George's opened by Catherine Zeta Jones is a smaller mall, but features a gym and a 9-screen vue cinema. Complementing the shopping centres are a number of high street shops and a large Debenham's department store.
