18hp Mini Tractor With Gear Transmission

The factors influencing tractor field operation performance include productivity, economy, and unit compatibility.

Factors affecting productivity: The actual working speed, width, and working time of the tractor are the main factors determining productivity. With a fixed engine power, increasing the working speed is more advantageous than increasing the width; narrow width and high speed are superior to wide width and low speed, especially in small fields where narrow turning radius is advantageous; reducing idle time during turns is also beneficial. Minimizing time spent on field transfers, field maintenance, and troubleshooting is an effective way to improve productivity.

Factors affecting economy: Economy mainly refers to the consumption of fuel and lubricants during operation. Fuel consumption during operation can be divided into fuel consumption under load, fuel consumption during turning, and fuel consumption during idle time. The fuel consumption actually used for work is fuel consumption under load. Therefore, field planning should be suitable for tractor operation, and reasonable field travel methods should be adopted to minimize the number of turns and idle time during field transfers. Furthermore, the operator's skill level is also closely related to fuel consumption.

The proper matching of the power unit and implements is crucial for maximizing the power performance of the tractor, which is key to improving productivity and economy in tractor operation. This requires that the traction force be compatible with the resistance of the implements. Whether the driving force can be fully utilized, even with sufficient traction, depends on soil conditions. In firm soil with sufficient traction, the driving force depends on the engine power. In loose soil with insufficient traction, the engine power cannot be fully utilized. Therefore, the driving force is determined by the adhesion between the wheels and the soil. This necessitates improving the walking mechanism and creating suitable tillage conditions. For example, four-wheel tractors should use anti-slip wheels and high-tread tires in the field, and the soil moisture content should be moderate. Muddy fields will cause the wheels to stick to the mud and slip, reducing traction. The resistance generated by the implements is related to the type of work, the type of implement, the working conditions, and the operational requirements. Before working in the field, the driver should estimate the appropriate speed based on the tractor's traction force and the width of the implements.
