When a track comes off the ground, the track will loosen and the track rollers may come off their links.
On hard surfaces the shock forces are larger and have an adverse effect on the undercarriage. Always keep
the correct track tension.
When the machine is operated on muddy ground, the tracks will fill with mud. If the machine travels in this
condition it will cause wear to the tracks. To decrease the wear, lift one track off of the ground at a time and
turn the track to remove the mud.
If the machine travels over obstacles for example tree stumps and rocks, the track shoes may bend and a high
load will be applied to the individual track pins.
If the machine must travel over such obstacles, drive the centre of the track shoes over the obstacles.
