Background

The crawler harvester is a widely used agricultural machinery equipment, and is a common machine for harvesting grains in agriculture. When the crawler harvester works, the crawler harvester often needs to turn to adjust the working path to harvest new crops. It is important that the steering operation be smooth, convenient, and accurate. If the angle of the crawler harvester is wrong when the crawler harvester turns, rolling is easy to generate on the operation, and loss is caused. And the crawler may not be able to accurately harvest the crop.

The crawler harvester needs to keep a correct angle with the crops, so that the harvesting mechanism can harvest the crops, and once the steering angle of the crawler harvester is incorrect, the harvesting mechanism cannot be aligned with the crops, so that the crops are difficult to harvest and can be lost.
