MECHANICAL
The International Harvester D-439 tractor features a two-wheel drive (2WD) chassis, which enhances maneuverability on flat, firm terrains but may struggle in soft or hilly conditions due to reduced traction. Its design prioritizes simplicity and lower maintenance costs, providing advantages in price and ease of repairs. However, the limitations in traction could hinder performance in applications requiring significant weight distribution, such as plowing or heavy hauling on uneven land.
