Heavy Equipment Diagnostics
Comprehensive mobile heavy equipment diagnostics Utah. Onsite health checks for engines, hydraulics, and electrical systems. Know the truth about your iron.

Full Machine Diagnostics: A Complete Health Check for Your Fleet
Not sure what's wrong with your machine? Sometimes a rig just 'doesn't feel right'-it's lost its punch, it's running hot, or the controls feel mushy. You need an expert eye to tell you why before you commit to an expensive repair. At Iron Horse Field Service, we perform complete machine health checks from the engine to the hydraulics and the electrical systems. We give you a clear, honest path to repair right there on your jobsite.
We check your pressures, read your historical codes, and inspect the mechanical wear points to give you a full picture of your machine's condition. I've helped dozens of contractors in Utah decide whether to 'fix or flip' a machine based on a professional diagnostic report. Knowledge is power, and in this industry, knowledge is profit! Don't just keep throwing parts at a problem-let us find the truth so you can make an informed decision for your business.
Whether you're buying a used machine and want a pre-purchase inspection, or you're planning a major project and need to know your fleet is ready for the stress, we're here to help. We're a licensed contractor with over 25 years of experience in the Intermountain West. We don't work for the dealers; we work for you. Let's get a professional diagnostic plan in place for your iron today. Rugged, honest, and high-tech-that's how we keep Utah moving!
Pre-Purchase Inspections: Know What You're Buying Before You Bid
Nothing hurts worse than dropping fifty grand on a 'low-hour' machine from an auction only to discover it needs a twenty-grand transmission rebuild. We offer comprehensive pre-purchase inspections for contractors and equipment buyers across Utah. We'll go through the machine with a fine-toothed comb—checking engine hours against wear patterns, testing hydraulic pressures, scanning for hidden fault codes, and inspecting the undercarriage for hidden damage. Our detailed inspection report gives you the negotiating power to avoid buying someone else's problem.
I've saved clients tens of thousands of dollars by identifying machines with cracked frames, failed accumulators, and doctored hour meters. A two-hour diagnostic investment can prevent a six-figure mistake. We don't work for sellers or dealers; we work for you, the buyer. If you're considering a used excavator, dozer, or loader, let us put it through a full health assessment before you commit. We also provide fleet condition audits to help you plan your maintenance budget for the next season. Knowledge is profit—call Iron Horse for a professional diagnostic evaluation.
