Best Tractors

Best Tractors

For example, in an extensively farmed area of Africa where hoe cultivation is used yields may be low, while in an intensively farmed tractorized region of India yields may be much higher. The yield differences may be caused in part by differences in other inputs, such as fertilizers or seeds. They could also be caused by better tillage in India-but this does not mean that good tillage is achieved only by tractors and cannot be achieved by hand. Examples from Java show that cultivation by hand can be as thorough as by ox or tractor.
It is thus no accident that rental markets for threshing machines were well established in the nineteenth century in the United States and are now common all over Asia (Gardezi and others 1979; Walker and Kshirsagar 1981). The contract-hire system for combines in the United States illustrates the problem of synchronized timing. The contractors achieve higher rates of machinery utilization by migrating to follow the harvest from the TexasOklahoma area to the northern states, where harvesting takes place months later.
