How tight should a rubber track be on a mini excavator?

Expert_Answer

A rubber track on a mini excavator should be tight enough to stay engaged with the sprocket and rollers, but not so tight that it creates excessive drag or premature wear. As a general check, with the machine lifted and the undercarriage supported, there should usually be a small amount of sag at the center of the track, according to the manufacturer’s specification for that model. Too much tension can overload the drive motor, idlers, and rollers; too little can cause the track to derail. The correct setting depends on the machine weight, track design, and working conditions, so always follow the OEM manual.
