Tractors for the Humankind
Tractors are self-propelled unit having wheels or trucks for operating agricultural implements and machines including trailers. This are farm machines that makes work easy and less tedious for humans. It also saves time and per tractor is measured on the capacity per horsepower of the engine. Moreover, the higher the engine power the greater consumption of fuels. These are iconic symbols of farmers which makes it popular as the rise of farmers in the industrial age of the world. Also, Prime mover is the tractor engine for agricultural tools and stationery from machinery through power take off shalt (PTO) or belt play.
Power Units our Ancestors in Our Modern World
Our early ancestors only do hunting at that time. Until, they realized their tools weren’t that effective and it was too tiresome. So these people began trapping animals and even fishes. Furthermore, they also gathered fruits from different fruit bearing plants. It was the discovery age of humankind. Then, they begin building communities and elected leaders. Then, this communities, begins to increase in population thus the need for more food. So, the elders of the organized society developed a system that they could grow food and breed animals.
Indeed, agriculture is center of humankind that we should protect. It is our history and it is our identity as human beings.Long before tractors came, agriculture is already present in the society. Since, it is because of agriculture human life has flourished. It has been the back bone of the economy since then of large empires. Even in Egypt, where the Pyramids of Giza was stood place agriculture was the driving force in their economy. Moreover, civilization were established near rivers because of irrigation, rich soil and transportation of good which were essentials of farming. Farming is a way of life, even our ancestors only use tools for farming.
Why tractors are important?
As the population of the society exploded, the demand for food also grew and supply must cope up to suffice the demand. True enough, human labor and animal draft weren’t enough to feed the society. Thus, engineers and scientist were able to find ways to mechanize the world. As the discoveries of diesel engine and fossil fuels, people tilled the land day and night. The production was high and not tilled lands were now filled with different crops. In addition, the human population continually grew until now. Medicines were also developed because agriculture. Indeed, life became easier because of agriculture.
Classifications of Tractors
Classification based on structural design
• Wheels tractor – Three (3) or Four (4) pneumatic wheels in the tractor.
• Crawler tractor – Track type or chain type tractor endless chain or track in the replace of a rubber pneumatic wheels.
• Walking tractor/ hand tractor – Power filler fitted with two wheels the directions of travel did its controls for field operations which is controlled by a single operator.
Classification based on purpose
• General purpose tractor – It is used in farm operations: plowing, harrowing, sowing, harvesting and transporting work.
• Row crop tractor – It is used for crops cultivations.
• Special purpose tractor –It is used for special jobs in marshy lands, hillsides and garden etc.

Factors in Selecting a Tractor
1. Land Holding – One (1) horsepower for every 1 hectare, thus a 20 to 25 horsepower tractor is suitable for 20 hectares.
2. Cropping pattern – It should be less than 1.0 horsepower/hectare for adequate irrigation facilities with more than one crop is taken, thus 30 – 35 horsepower tractor is suitable for 25 hectares.
3. Soil Conditions– A tractor with less wheel base, high ground clearance and low overall weight will successfully in higher soil will not give sufficient depths in black cotton.
4. Climate condition- For very hot zones and desert areas, air cooler engine are preferred on water cooled engine. Similarly,for higher altitudes, air cooled engine are preferred because water will freeze at higher altitude.
5. Repairing Facilities– The purchased tractors should have dealers nearby and technical skills are available for repair and maintenance.
6. Running cost – Tractors with less specific fuel consumption should be preferred over the others so running cost will be less.
7. Initial cost and resale value– While keeping the resale valve high initials cost should not be very high, otherwise higher amount at interest will be paid.
8. Test report – Test report for tractors rebated form farm machinery testing stations should be consulted for guidance.
Think twice farmer!
