Why the Front Idler Matters
Engineered for Guidance & Tension
The front idler on your Kubota KX057-5 sits at the front of the track frame and is a key part of the tensioning system. As the track adjuster is greased, the idler moves forward to take up slack, keeping the rubber track tight on the undercarriage. A worn, seized, or damaged idler leads to track slap, accelerated track and roller wear, and de-tracking.
Our replacement idlers are manufactured from high-strength cast/forged steel, heat-treated for surface hardness and core toughness, and built with sealed, durable bearings to keep out dirt and moisture for reliable performance in demanding conditions.
Why Choose Our Replacement Front Idler for Your Kubota KX057-5?

Front Idlers & Your Undercarriage System
The front idler guides the track and maintains tension at the front of the undercarriage.
Keep Your Undercarriage Healthy
Undercarriage components account for over half of a machine’s lifetime maintenance cost. Inspect your front idler regularly for wear on the running surface, flange damage, and bearing play. Prompt replacement of a failing idler prevents more expensive damage to your tracks, rollers, and sprocket.
