The average life of a tractor is 8-10 years. However, tractors that are maintained properly and have not been used in highly extreme conditions can easily last up to 12-15 years.
but also the life of a tractor in years depends on its built quality, usage, power, and climatic conditions of the regions where they are used. Generally, a tractor's life expectancy is estimated in terms of hours of operation rather than years since the number of hours it operates is a more accurate representation of its wear and tear.
and in terms of hours, a tractor's lifespan is at least 4000 hours and goes up to 10,000 hours.
