The foot plough is a type of plough used like a spade with the foot in order to cultivate the ground.

Before the widespread use of metal farm tools from Europe, the Māori people used the kō, a version of the foot plough made entirely of wood.^[1][2]

Prevalent in northwest Scotland, the Scottish Gaelic language contains many terms for the various varieties, for example cas-dhìreach 'straight foot' for the straighter variety and on, but cas-chrom 'bent foot' is the most common variety and refers to the crooked spade. The cas-chrom went out of use in the Hebrides in the early years of the 20th century.

Describing the Scottish Highlands around 1760, Samuel Smiles wrote:

The plough had not yet penetrated into the Highlands; an instrument called the cas-chrom, literally the "crooked foot"- the use of which had been forgotten for hundreds of years in every other country in Europe, was almost the only tool employed in tillage in those parts of the Highlands which were separated by almost impassable mountains from the rest of the United Kingdom. The cas-chrom was a rude combination of a lever for the removal of rocks, a spade to cut the earth, and a foot-plough to turn it. ... It weighed about eighteen pounds.  In working it, the upper part of the handle, to which the left hand was applied, reached the workman's shoulder, and being slightly elevated, the point, shod with iron, was pushed into the ground horizontally; the soil being turned over by inclining the handle to the furrow side, at the same time making the heel act as a fulcrum to raise the point of the instrument.  In turning up unbroken ground, it was first employed with the heel uppermost, with pushing strokes to cut the breadth of the sward to be turned over; after which, it was used horizontally as above described.  We are indebted to a Parliamentary Blue Book for the following representation of this interesting relic of ancient agriculture.  It is given in the appendix to the 'Ninth Report of the Commissioners for Highland Roads and Bridges,' ordered by the House of Commons to be printed,19th April, 1821. ^[3]

It was an implement of tillage peculiar to the Highlands, used for turning the ground where an ordinary plough could not work on account of the rough, stony, uneven ground. It is of great antiquity and is described as follows by Armstrong:

It is inexpeditious in comparison with the plough, eight men being necessary to dig as much with it in one day, as a horse would plough in the same time. It is chiefly used for tillage, and consists of a crooked piece of wood, the lower end somewhat thick, about two-and-a-half feet in length, pretty straight, and armed at the end with iron made thin and square to cut the earth. The upper end of this instrument is called the ‘shaft’, and the lower the ‘head’. The shaft above the crook is pretty straight, being six feet long, and tapering towards the end which is slender. Just below the crook or angle, there must be a hole wherein a straight peg must be fixed, for the workman’s right foot in order to push the instrument into the earth; while in the mean time, standing on his left foot, and holding the shaft firmly with both hands, when he has in this manner driven the head into the earth, with one bend of his body he raises the clod by the iron-headed part of the instrument, making use of the ‘heel’ or hind part of the head as a fulcrum. In so doing, he turns it over, always to the left hand and then proceeds to push for another clod in the same form. To see six or eight men all at work with this instrument, standing on one leg and pushing with the other, would be a curious sight to a stranger. With all of its disadvantages, the cas-chrom is, of all the instruments, fittest for turning up the ground in the country, for among so many rocks, a plough can do little or nothing, and where there are no rocks, the ground is generally so marshy that cattle are not able to pass over it without sinking in deeply.

In the Western Isles, with a foot plough, one man can perhaps do the work of four men with an ordinary spade, and while it is disadvantaged compared to a horse-plough, it is well suited to the country.

The most advanced agricultural tool known in the New World before the coming of the Europeans was the Andean footplough, also known as the Chakitaqlla or simply taklla. It evolved from the digging stick and combined three advantages: metal point, curved handle, and footrest.^[4] No other indigenous tool utilized the pressure of the foot in digging up the sod which made it different from all farming implements known elsewhere in the Americas in pre-Columbian times.^[5] Although Chakitaqlla is a relatively simple instrument, it has persisted long after more sophisticated technology was introduced into the Central Andes, and its enduring presence demonstrates that more advanced innovations do not necessarily displace primitive forms that under certain conditions may be more efficient.

Historic distribution and the current diversity of forms point to the mountainous region of Southern Peru as the likely place of origin of the chakitaqlla.^[4] With the expansion of the Inca Empire, the taklla was carried north to Ecuador and south to Bolivia where early colonial writings confirmed its presence.^[6] It probably never occurred in Southern Chile, either before or after the conquest by the Spaniards.^[7]

It is probable, nevertheless, that agricultural peoples living on the Peruvian coast long before the Incas contributed to the idea of the taklla. Copper-shod digging sticks known by the Mochica culture (c. 500 CE) may have been a forerunner of the taklla.^[8] Pottery representations and remains of proto-taklla tools from the Chimu culture (1300 CE) on the coast verifies its development by at least that time.^[9] However, the friable soils of the coastal desert were easily turned without the taklla, and the incentive to develop such a tool probably came from the adjacent Highlands.

Men wielded the plow, called a chakitaqlla. It was made of a pole about 2 metres (6 ft 7 in) long with a pointed end of wood or bronze, a handle or curvature at the top, and a foot rest lashed near the bottom.^[10]

The Inca Emperor and accompanying provincial lords used foot ploughs in the "opening of the earth" ceremony at the beginning of the agricultural cycle.^[11] Incan agriculture used the chaki taklla or taklla,^[12] a type of foot plough.

Chakitaqllas are still used by peasants farmers of native heritage in some parts of the Peruvian and Bolivian Andes. Modern chakitaqllas have a steel point.
