Why Used Diesel Gensets Hold Their Value
A diesel generator is one of the few pieces of industrial equipment that can outlive the building it powers. Heavy iron engines from Caterpillar, Cummins, MTU, and John Deere are routinely rebuilt two and three times, which keeps a deep resale and export market bidding on used units year-round. When your facility upgrades, downsizes, or decommissions, that market is why the machine on your pad is worth real money — not scrap weight.
We purchase diesel generators in every configuration: open-skid plant units, weather-protective and sound-attenuated enclosures, units on sub-base fuel tanks, and trailer-mounted rental machines. Standby-rated, prime-rated, and continuous-rated units all qualify. If your machine burns diesel and is bigger than 50 kW, it belongs on this page.
What Drives Our Diesel Offers
kW Rating & Engine Model
The engine family (3512, QSK60, Series 4000) sets the market. Bigger iron, bigger numbers.
Emissions Tier
Tier 4F earns domestic premiums; Tier 2–3 sells strong into export and standby markets.
Hours & Service History
Low-hour standby units top the market, but documented high-hour units still sell well.
Enclosure & Tank
Sound-attenuated enclosures and sub-base tanks add resale value — and add to your offer.

From Nameplate to Payment
The fastest path to a number is a photo of the data tag: text it to 954-740-1983 with the hour-meter reading and your city. We research recent comparable sales, come back with a firm offer — usually within one business day — and once you accept, payment is issued before our rigging and freight team touches the unit. The full sequence is laid out on our how it works page, and we buy in all 50 states.
Diesel Generator FAQs
Does emissions tier affect what my diesel generator is worth?
Significantly. Tier 4 Final units command premium pricing for domestic resale, while Tier 2 and Tier 3 machines remain strong sellers into export and standby-only applications. Either way, the tier is on the nameplate — send it and we'll price accordingly.
How much do run hours matter on a diesel genset?
Less than sellers fear. A well-maintained diesel with 20,000 prime-power hours still has decades of life. Hours set the price bracket, but maintenance records, oil samples, and load-bank history can move a unit up a bracket.
Do you buy diesel generators with wet-stacking or smoke issues?
Yes. Wet-stacking from chronic light loading is common on oversized standby units and is usually recoverable. Describe the symptoms honestly and we'll factor a load-bank service into our offer instead of rejecting the unit.
