Wear Parts Cost — Excavator Undercarriage
Per-hour accrual for excavator undercarriage from set cost, life and severity.
Undercarriage is ~20% of an excavator's operating cost and 100% measurable: track gauges convert bushing and grouser wear into percent-consumed. Side-hill work, sharp rock and high travel speed are the three multipliers that halve the life this calculator assumes.
