* Compatibility with the size of the engine size of the machine
* Add some additional capacity to meet some business-critical
3 - Compatibility with the farm tractor-drawn machines:
Factors to consider when choosing a tractor for agricultural work, which falls on agricultural machine needed:
* Do not download loads of redundant farm tractor
* Lift the machine as soon as the recommended
* To take the situation and soil conditions and their impact on the performance of the machine
* Plow dump Mtrahi: 1275 kg / m View (power factor)
* Mower: 195 kg / m
* Machine harvest: 562 kg / m
4 - The method of estimating available capacity of the tractor back on the shaftor rod tensile
To determine the required size of the farm tractor is the ability to use a simple relationship to determine the required capacity of the farm tractor to perform some operations on several types of agricultural land:
If the motor power = 86.5 kW
* The ability to rear shaft = 0.86 x86.5 = 74.4 K. W
* Maximum capacity of the tensile bar (the land of concrete) = 0.86 x74.4 = 64 k. Watt
* Maximum capacity of a tensile bar (ground fixed) = 0.86 x64 = 47.3 K. W
* Maximum capacity of the tensile rod (plow) = 0.86 x64 = 40.7 K. W
* Maximum capacity of the tension rod (the land of sand) = 0.86 x40.7 = 35 k. Watt

5 - Determine the number of units of the farm mechanization optimal:
Factors affecting the optimal size of units of agricultural machinery:
* - The nature of the soil
* - The number of tractors and agricultural machinery available
* - The nature of the agricultural exploitation of the farm
* - Compatibility with existing agricultural machinery tractors available
* - Length of time required to finish the process of agricultural
* - The efficiency of existing farm machiner
6 - Estimating need for farm tractors and agricultural machinery
Know the various elements affect the determination of need for the farm:
* Land area
* The nature of agriculture and crop type
* Productivity of the machine
* The time available to complete the process of agricultural
* Types of agricultural operations to be mechanized
* Operating speed

There are several ways to calculate the installation of a unit of agricultural mechanization (agree with the tractor agricultural machine)
1 - experimental methods:
Adopt the recommendations proposed by the manufacturers of machinery, some specialists in this area
Tested the unit on the basis of speed and efficiency of use of the engine
Conducted some tests for optimal operation (speed & Display machine)
2 - calculation method:
Include a different account types to install a unit and its effectiveness is then the optimal choice of form and verification of the experiment and divided this way to:
First / graphic way
This method uses the curves of the tensile properties of the agricultural tractor and which is available from a test farm tractor is an easy way and with appropriate resolution
May not be this way always available due to lack of tensile curves for all machines and under all circumstances
3-analytical method:
It is the most common method by which it is the expense of the unit is installed in accordance with the following steps:
1. After choosing the type of machine involved in the unit determines the speed according to the requirements and characteristics of agricultural machinery
2. Determine the value of tensile strength of the natural agricultural tractor speeds required to work from 2-3 speeds and these values are taken from special tables or curves of tensile properties of the agricultural tractor
3. Calculates the largest display of the unity of machines can be loaded farm tractor engine completely when a certain speed
4. Calculated the number of machines by the largest display of the Unit and the machine selected
5. Calculated resistance of the unit by the total resistance resulting from the machine which is about the weight and hydraulic arms of the clamp and the resulting resistance of the overall width of the unit
6. Calculated the degree of agricultural tractor load of each type of species calculated
After the piece is the expense of productivity and fuel consumption for each type and compare the results for all machines where the selection of the optimal
When similar machines in the production and consumption of fuel is calculated by the degree of loading because the load to achieve optimum productivity increase and economic work
Is verified by experience of the type calculated in the field
