When sourcing a farm truck, you must prioritize engine displacement and torque to ensure the vehicle can handle heavy loads on uneven terrain. Look for 4WD (Four-Wheel Drive) capabilities and high ground clearance (minimum 200mm) for off-road stability. Additionally, verify the payload capacity and towing weight limits to match your specific agricultural needs, such as transporting grain, livestock, or machinery. For durability, ensure the chassis is made of reinforced high-strength steel with anti-corrosion coating to withstand exposure to fertilizers and moisture.
