Sources Of Farm Power
# There are different source of farm power available in Nepal which are:
- Human power
- Animal power
- Mechanical power (Tractors & Powertillers + oil engine)
- Electrical power
- Renewable energy (Biogas, solar energy + wind energy)
Human power:
→Human Power is the main sources for operating small implements and tools at the farm.
→ Stationary work like chaff cutting, lifting, winnowing etc are also done by manual labor. An average man can develop maximum power of about 0.1 hp for doing farm work.

→Besides bullocks other animal, like camels, buffaloes, horse, donkeys, mules, and elephants are also used at some places.
→The average force a draft animal can exert One-tenth of its body weight.
# Mechanical power p → Broadly speaking, mechanical power includes stations -dry oil engines, tractors, Power tillers, and self
Propelled combines.
