An excavator track adjuster is a device that is used to adjust the tension of the tracks on an excavator. It is designed to keep the tension in the tracks at the correct level, as too little tension can cause the tracks to slip, while too much tension can cause wear and tear. 
The track adjuster works by applying tension to the tracks.The track adjuster can be adjusted and guidance will be given in the machines operator manual. This will ensure that the tracks are at the correct tension and will last longer.The track adjuster is located at the rear of the excavator and is usually operated by a hydraulic system.
An excavator track adjuster is important for keeping your excavator running smoothly. If the tension in the tracks is too low, the tracks can slip and cause damage to the excavator. Too much tension can also cause wear and tear on the tracks, leading to a shortened lifespan. Keeping the tension in the tracks at the correct level ensures that your excavator runs smoothly and lasts longer. Weak or broken track adjuster springs and poorly functioning adjusters can cause detracking issues and lead to shortened track and idler life.
