Therefore, agricultural machinery operating units must reasonably select the supporting agricultural tools of the tractor to give full play to the role of the tractor.

8. Construction tractor

The durability and engine power of the tractor make it the most suitable for engineering tasks. Some engineering tools are often installed on tractors, such as bulldozers, bulldozers, reloading equipment, buckets, cultivating equipment, harvesters, etc. Bulldozers and buckets are often installed in front of the tractor. After the tractor is installed with engineering tools, it is usually named as an engineering vehicle.

The bulldozer is usually a crawler tractor with blades at the front and a rope winch at the back. A bulldozer is a very powerful tractor, and it has very good contact with the ground. Its main task is to push or pull things.

Bulldozers have been constantly developing, with more and more new products, and have functions that the previous tractors did not have. A loader is an example. He replaces the original blade with a large bucket, and uses a hydraulic arm to raise or lower the bucket, so it is easy to pick up dirt, rocks and soft materials and load them on the truck.

The front-loading loader and the loader are tractors with engineering tools. They have two hydraulically powered arms, which are installed on both sides of the front cabin. There is also a dumping device, which is actually a bucket with a larger opening. The flat fork or baler is installed.
