When selecting a tractor, horsepower is a critical factor. Small-scale farmers often opt for tractors within the 20-30 HP range, while large-scale operations require more than 50 HP. Indian tractor manufacturers like Mahindra, TAFE, and Sonalika offer models with various horsepower levels, ensuring that farmers can choose the right machine for their specific needs. Fuel efficiency and performance are key considerations, making these brands top choices for Indian farmers.
