The main components of the undercarriage are the following components: pivot shaft (5), equalizer bar,, front track roller frame (4), rear track roller frame (2), track rollers (6), front idler (7), rear idler (4), recoil and track adjuster group (inside front roller frame) and tracks (1) .
Pivot shaft (5) connects the roller frames to the tractor main frame. Each track roller frame can oscillate at the pivot shaft.
The equalizer bar connects the two roller frames at the front of the tractor. The oscillation of the roller frames is controlled by the equalizer bar.
The track roller frames consist of front frame (3) and rear frame (2) . Front idler (7) is installed on the front frame. Rear idler (4) and track rollers (6) are installed on the rear frame. A track adjuster and recoil group that is installed in front roller frame (3) protects the undercarriage and the final drives from overloads. This also keeps the tracks adjusted.
Tracks (1) are sealed and lubricated for increased wear.
