In the harvesting operation, it is common for the self-propelled combine harvester to encounter muddy feet (about 200mm) and no hard floor, especially during the summer. It is very difficult for the self-propelled combine harvester to break the track in such a field or to remove the crawler during operation and reinstall the track. So how can we install the track easily and quickly in this deep mud foot field? Now provide some tips to help the operators operate.

In the mud, the two groups of rollers in the center also dig a little (no adhesion or adhesion is small when the track rotates); third, remove the guide wheel brackets and two telescopic tubes to press the guide wheel brackets back to the machine. In the guide trough, fourthly, replace the crawler with guide wheels and drive wheels. Fifth, start the diesel engine and hang a low gear. Pull the separate brake handle without pulling off the track and slowly lower the travel clutch. The track can then be The positive position was quickly installed by the engine.
