Manual Extract Track Tension Adjustment

Loose track chains tend to climb sprocket teeth and will jump under heavy pulls. Track chains that are kept too tight will cause undue wear on pins, bushings and front idler bearings.
To check the track tension adjustment:

1. Check on hard surface.
2. Drive unit to remove slack from under machine.
Place a straight edge across the sag in the track between the drive sprocket and the top rear roller. Measure the distance between the bottom of the straight edge to the top of the track at its lowest point.
