Answer:
Tractors are mechanical and they can break down; you must have access to repair parts, tools, and knowledge on how to effect the repairs. They also require routine maintenance and clean fuel. Tractors burn fossil fuels (some engines may run ok on biodiesel) and cause air pollution and waste products such as used oil and filters that must be properly disposed of to avoid contaminating ground water.
It must be noted, however, that farm animals also generate methane gas and their waste can contaminate water sources as well, and beasts of burden also require fuel (hay, grass, grain, etc.).
On the other hand, tractors can dramatically improve the productivity of farming by increasing the amount of land that one person can effectively farm.
