Tractors with a diesel engine have several advantages:
- Torque and Power: Torque refers to the twisting force. For example, the force required to undo a nut on a screw using a spanner is torque. With tractors required for heavy-duty work such as pulling heavy loads and ploughing fields, the torque in the tractor engine is crucial. Diesel engines deliver a high torque output, enabling the efficient performance of these tasks.
- Fuel Efficiency: When compared with petrol engines, diesel engines are more fuel-efficient. Due to their higher compression ratio and ability to operate at a leaner air-to-fuel ratio, a diesel engine has better thermal efficiency. The engine is able to convert a higher percentage of the energy in the fuel into usable power, making them more economical for long hours of tractor operation.
- Durability and Longevity: Tractors are required to work long hours in all types of terrain and weather conditions. Diesel engines are designed to handle these harsh operating conditions and heavy loads. They are built to be robust and durable, making them perfect workhorses for the demanding nature of agricultural work.
- Versatility: Diesel engines are able to run on various types of diesel fuel, including biodiesel and blends, and the fuel can be stored for longer periods without deterioration compared to petrol. Diesel fuel is also easily accessible in rural areas. This versatility, availability and compatibility makes a diesel engine tractor the obvious choice for farmers who benefit from that flexibility no matter what region they work in.
- Low-End Torque: Diesel engines have higher torque at lower RPMs compared to petrol engines, which is referred to as ‘low-end torque’. Tractors need to be able to function in any type of terrain, no matter how challenging, and a diesel engine provides the low-end torque that is able to handle the workload, such as being able to pull heavy loads from a standing start.
- Reliability: Tractors are often worked long hours in rough terrain and in all weather conditions, so they need to be reliable. Diesel engines are known for their reliability. They are able to handle heavy workloads and extended operation dependably without frequent maintenance or refuelling.

Overall, diesel engines offer the necessary torque, power, fuel efficiency, durability, longevity and reliability needed for agricultural applications.
They are well-suited for heavy-duty tasks, long hours of operation and the challenging conditions commonly encountered in farming and tractor operations.
