A modern farmer has a different mission than other citizens of this earth! The modern farmer has to feed the growing population without affecting the ecosystem. Taking into consideration the different types of work a farmer has to undertake, he needs a versatile machine; there is no machine which is versatile other than a tractor. With the right type of implements, a good quality tractor can perform agricultural and non-agricultural tasks.
Tractor Size and Style
While looking for a tractor, first do a research and understand all about tractors. You are already there because you are reading this page. Determining the perfect size and style is very important step in buying a tractor because nowadays you could see that we have standard tractors to suit versatile tasks and specialized tractors for specific functions. Let us first understand the type of tractors! Following are the common list of tractors:
1. Normal Tractors
2. Row-Crop Tractors
3. High-Crop Tractors
4. Utility Tractors
5. Garden Tractors
“Standard” tractors are mainly used for wheat or paddy cultivation and used in heavier field applications. Their front wheels are fixed on a wide axle and they have a low center of gravity.
Row-Crop tractors are used for cultivating row crops such as tomatoes, corn. They have adjustable tread width so that they pass over crops without damaging them.
High Crop Tractors
High – crop tractors are used for cultivating tall plants like cotton or vegetables. Their tread width is adjustable and they have very high clearance to help pass over crops without damaging them.
Utility tractors are used for different variety of work, with attachments/implements such as front-end loaders, backhoes, etc . Generally they are small in size with a small turning radius.
These are basically Lawn tractors used for mowing the lawn. They are not high powered and cannot accommodate implements.
So far you have understood about the type of tractors. Now you need to understand the power of a tractor, which is the usable output of a tractor. Normally the power of a tractor is measured in engine horsepower. If you are planning to perform utility tasks using implements or attachments then you need to understand PTO, which is the Power Take Off of any tractor. This is the second horsepower of a tractor you need to notice because the PTO number only corresponds to the true power available to the implements or attachments of a tractor. The tractor’s engine rotates a shaft at the rear of the tractor from which the implements or attachments get the power to operate and perform the desired the farm function. Calculate your type of work you would be performing on your farm and then buy a tractor with little more engine horsepower so that you would not regret in the future when you become an expert in using a tractor.
The three-point linkage or three-point hitch is the point where the implements are attached to an agricultural tractor. The three point look like a triangle or the letter A. By attaching through a three point-linkage or hitch, the orientation of the implement is fixed. When the implement is not in a fixed position the implement is attached through a draw bar.
When the implement exerts a drag force, the linkage or hitch helps to increase the downward force on the rear wheels to make the traction available.
The three-point linkage or hitch utilizes the tractor’s hydraulic system and has attaching points, lifting arms and stabilizers. The two lower arms that help to lift, lower and tilt are controlled by the tractor’s hydraulic system. The upper center arm is movable but not connected to the hydraulic system.
Based on the horsepower of the tractor, categories of three-point linkage or hitch are determined.
Tractors 20 HP: Category Zero (not common)
Tractors 20 to 50 HP: Category One
Tractors 50 to 90 HP: Category Two
