Oldest sources of power in the farm
HUMAN AND ANIMAL POWER
Man used his muscles to walk long distances, hunt animals and till the soil.
Man learned to tame animals he hunted for food to work for him by providing pulling power.
Man learned the use of sleds for transporting cargoes; use of rollers underneath the sleds; and finally the use of wheels.
While fire is considered the greatest discovery of man; the wheel is the considered the greatest invention of man
Today, still considered the major sources of power in the farm because of:
human and animal power
greatest invention of man
wheel
Poor source of power.
Develops only 0.1 hp working continuously under favorable conditions (good health, well fed, and favorable environment).
Considering that there are 3M farms, 12M hectares of agricultural lands, and assuming 5 farmers per farm, human power contribution is about 0.125 hp/ha.
Man is suited to farm operations requiring judgment rather than simple power.

In the Philippines, the Carabao is the major beast of burden.
It can generate 1 hp walking continuously under favorable conditions.
Its work is confined mostly to pulling operations such as plowing, harrowing, cultivating and transport.
There are about 2.7M carabaos in the Philippines and about 70 75% is used for draft work.
The contribution of animal power in the farm is about 0.16 hp/ha.
