Study on the Plowing Capacity of the 4 Wheel Tractor (XII)

Capacity by the Rotary

Abstract

We made rotary-plowing by tractors in table 1, table 2 indicates turning time which effects efficiency, and in direct plowing it does little more than calculative value, while in rotational plowing little less.
It is thinkable of this difference than standard of calculations was taken at directly under the rear wheel, but in actual working directly under the work machine.
Every tractor indicated maximum in alternated plowing method, second in succesible plowing method and third in rotational plowing method by efficiciency curve on three plowing methods in figure 1. And on type of tractors, A-tractor which has few turning time is great, B-tractor comes after and C-tractor is least.
Figure 2 is the capacity curve of multiplying plowing width and plowing speed by these efficiency value. On the plowing method, each tractor has a tendency to bear a resemblance to the efficiency like indication of the figure, which type of tractors, C-tractor which has lowest efficiency has best field capacity, and A-tractor which has highest efficiency has least. In brief, the capacity will have much influenced because the varience of plowing width is more than efficiency.
Next, the value of capacity of B-tractor compared with plow-plowing is indicated in table 3. We judge by this table that rotary-plowing is superior to in alternated plowing method, and in rotational plowing method, plow-plowing is slightly better.
In the last analysis, development of plowing capacity and reduction of working time need the large sized tractor of powerful HP and use it which plowing width is increased, more over it is good to manage the field by alternated plowing method.
