4WD 拖拉机（四轮驱动拖拉机）

概述

A 4WD tractor is a tractor that delivers engine power to all four wheels. Unlike a 2WD tractor, which mainly relies on the rear wheels for traction, a 4WD tractor provides greater traction, pulling capacity, and stability. It is especially useful in wet, muddy, sandy, or hilly conditions. Modern 4WD tractors often come with power steering, differential locks, hydraulic systems, three-point hitches, and comfortable cabs. They are widely used for heavy tillage, plowing, seeding, harvesting, transport, and other demanding farm operations. In short, a 4WD tractor is a powerful and versatile machine designed for efficient performance in difficult working conditions.
