The Economics of Excavator Maintenance Excellence
Excavators represent significant capital investments, often ranging from $200,000 to $800,000 or more. However, the true cost of ownership extends far beyond the initial purchase price. Poor maintenance practices can result in catastrophic failures costing $50,000-$150,000 in repairs, while proper maintenance protocols extend machine life from 8,000 to 20,000+ hours of operation. Professional maintenance strategies can reduce total ownership costs by 40-60% while maximizing productivity and uptime.
