在农村中拖拉机是一个有力的劳动者,同时也是农民得力的助手。它的力量和速度比牛马大几十倍。它能干轻活也能干重活,能运输也能固定作业。不论是耕翻耙地,播种栽植,中耕除草还是喷粉喷雾、收获脱粒、排灌抽水、开沟筑垅、送粪运货、农村发电等,几乎都用得上它。但是现在的拖拉机重量很大,需要消耗大量钢材,而且功率越大,重量也就越大、消耗的钢材就越多;它的体积愈庞大,转弯抹角愈不灵活,不方便;另
In the countryside, tractors are a powerful laborer and also a helpful assistant for farmers. Its strength and speed are dozens of times greater than cattle and horses. It is able to work lightly but also able to do heavy work. It can transport and fix operations. Whether ploughing land, sowing planting, cultivating weeds or dusting sprays, harvesting threshing, pumping and pumping water, trenching, transporting dung, transporting electricity to rural areas, etc., almost all of them need it. However, the current tractor is very heavy and needs to consume a large amount of steel, and the higher the power, the greater the weight and the more steel it consumes. The larger its volume, the less flexible and inconvenient it is to turn corners.
