拖拉机大修：从拆卸到组装，重获新生

她拆卸了拖拉机，把它们分解成几个基本部件，比如发动机、变速箱、传动系统和车架。为了确保拖拉机能够正常运转，她还必须检查发动机、更换机油和润滑油，检查变速箱、更换滤清器、检查传动系统、更换活塞环、检查车架以及更换底盘。完成这一切后，她又重新装上了拖拉机，并进行了试验，最后把它放在原来的位置上。

After disassembling the tractor, she broke it down into several basic components such as the engine, transmission, drivetrain and frame. To ensure that the tractor would work properly, she had to inspect the engine, change the oil and lubricants, check the transmission, replace the filter, inspect the drivetrain, replace the piston rings, inspect the frame, and replace the chassis. After completing all of this, she then reassembled the tractor and tested it, before putting it back into its original position.
