How do you value a used machine by its hours?

The hour meter tells you how much, not how

The hour meter counts hours with the engine running. It's the easiest figure to read and that's why it weighs so much in a negotiation, but it's only the starting point. Two machines of the same model with the same hours can be in very different shape: one loaded loose material with on-time service; the other broke rock with a hammer and skipped oil changes.

That's why there's no serious «at so many hours it's worth so much» table. What does exist is a method to put the hours in context, and it's the one every experienced buyer uses.

First calculation: hours per year

Divide the hour-meter hours by the years since the machine was built. The result tells you how intense its life was. Two units published on Constru Usados in October 2026 show it well: a 2023 Komatsu PC200-10M0 excavator with 5,592.6 hours worked about 1,860 hours a year; a 2016 Link-Belt 290X2 excavator with 4,461.1 hours, about 450 a year. The newer one has more hours; the older one spent more time parked.

Neither reading is good or bad on its own. Many hours a year usually come from fleets that work every day with scheduled service. Few hours a year on an old machine call for checking what deteriorates with time rather than use: dried-out seals and hoses, batteries, corrosion and stale fuel in the tank.

Condition weighs more than hours

What really defines a used machine's value is how much life its major components have left and what it would cost to replace them. Each wears at its own pace, depending on the work and the maintenance, and not all at once. Ask about each one: is it original or has it been repaired or rebuilt? When, and with what paperwork?

• Engine: the most expensive component; a rebuilt engine with invoice and date changes how you read the hours.
• Hydraulic system: pumps, swing and travel motors, cylinders.
• Transmission and final drives, on wheeled and tracked machines.
• Undercarriage or tracks: on a tracked machine it's one of the biggest items; its wear is measured, not worked out from hours.
• Structure: boom, arm and frame free of cracks or poor repairs.

History gives the hours their value

Credible hours are the ones that match a history: services with dates and hour-meter readings, filter and oil changes, repairs with invoices. If services follow the manufacturer's interval, the hours tell a story of care; if there are long gaps, they tell another.

On a Komatsu with KOMTRAX, the telematics history adds what paper doesn't: real hours, idle time, hours per operating mode (for example, in hammer mode) and alerts. Ask for it before negotiating. On Bobcat, Machine IQ keeps hours and maintenance records.

What it worked on: same hours, different wear

A thousand hours don't wear the same everywhere. Quarries, rock, hydraulic hammers, salty air or water and mud speed up wear on pins, undercarriage, structure and seals. Loading loose material, urban work or yard work is gentler. A rental-fleet machine usually has many hours, but with scheduled maintenance and several operators; a single-owner machine usually has one regular operator and steadier use.

Always ask what the machine worked on and ask for photos or a site visit. If it logged many hours in hammer mode, check the structure and pins more carefully.

Check that the hours are real

An hour meter can be replaced after a failure, and that's normal if it's documented. What isn't normal is hours that don't match anything. Compare the reading with the service history and, if available, with telematics. If the wear on pedals, seat, steps, pins and undercarriage looks like many more hours, ask for an explanation before going further.

If you're selling or trading in yours

What you look for as a buyer is what you need to show as a seller. Gather the hour-meter reading with a photo, the dated service history, invoices for major repairs and, if it's a Komatsu, the KOMTRAX report. A machine with organized paperwork is valued better and faster. At Grupo ConstruMarket you can offer it for sale on Constru Usados or hand it over as part of the payment for a new one with the trade-in plan; its value comes from a technical inspection of the unit.

How it works at Constru Usados

Constru Usados units are inspected and published with their hour meter, their year when known and their condition, and are sold as is. If you want repairs or maintenance before delivery, they're quoted separately and reviewed with you before closing. You can inspect the unit at the yard before buying. The inventory rotates; each unit's listing says which country it's in.
