Komatsu's PC series mini excavators are worksite staples from residential landscaping to heavy commercial excavation. These machines demand tracks that can handle the digging forces, ground conditions, and daily abuse that come with excavation work.
Komatsu PC Series Track Specifications
Komatsu mini excavators span a wide range of operating weights, and track sizes vary accordingly. Here's the breakdown by model class:
PC15/PC18 Class (1.5-2 ton): These compact units typically run 230x96x36 or 250x72x45 tracks depending on configuration. The narrow width allows access to tight residential spaces while maintaining adequate ground pressure for soft soil conditions.
PC25/PC27/PC28 Class (2.5-3 ton): Moving up in size, you'll find 300x52.5x80 or 300x52.5x84 track configurations. The 52.5mm pitch is standard across most Komatsu mini excavators in this weight class.
PC30/PC35 Class (3-4 ton): These machines commonly use 300x52.5x84 or 350x52.5x86 tracks. The wider 350mm option provides better flotation for softer ground conditions.
PC45/PC50/PC55 Class (4.5-6 ton): Larger mini excavators require proportionally wider tracks — typically 400x72.5x72 or 400x72.5x74 configurations. The 72.5mm pitch handles the increased machine weight and digging forces.
PC60/PC78 Class (6-8 ton): The largest Komatsu mini excavators run 450mm wide tracks with 71-76 links depending on the specific model year and configuration.
Understanding Komatsu Track Patterns
Komatsu excavators use several different guide patterns depending on the undercarriage design. The most common configurations are offset block guides and center-mounted guides. Identifying your machine's guide pattern is critical for proper fitment — installing the wrong guide type can cause derailment, premature wear, and undercarriage damage.
Check the inside of your existing tracks to identify the guide configuration before ordering replacements. TrackTECH can verify your exact requirements if you provide your machine's model and serial number.
Maximizing Track Life on Excavators
Excavators are harder on tracks than most other compact equipment due to the constant pivoting, repositioning, and exposure to abrasive materials. A few practices will extend your track life significantly:
Minimize counter-rotation — turning the machine by spinning one track forward and one backward causes maximum track stress. Use wider turns when possible. Keep tracks clean of mud and debris that can pack into the undercarriage and accelerate wear. Maintain proper track tension — excavators with over-tensioned tracks see dramatically reduced service life.
