The Ranger 225 on this listing is powered by a Kohler OHV Command CH730 gasoline engine, 23 HP @ 3600 RPM. Kohler engines in this line are gasoline or LP-Gas — there is no Kohler diesel in the Lincoln engine-drive range. Lincoln’s current engine-warranty document brands Kohler as Rehlko (formerly Kohler).

Yes — this is a factory demo or low-hour unit directly from Lincoln Electric. Units may show light cosmetic marks from display use but are mechanically sound. The warranty on this unit is the same as on a new machine. Lincoln’s Industrial Limited Warranty (form IMWS1, Apr-2026) lists a 3-year warranty period for “All Lincoln welding machines, wirefeeders & plasma cutting machines”, and Lincoln states: “Lincoln will assume both the parts and labor expense of correcting defects during the warranty period.” As on a new machine, the engine is not covered by Lincoln’s warranty — Lincoln states: “All engines and engine accessories are warranted by the engine or engine accessory manufacturer and are not covered by this warranty.” This machine’s Kohler OHV Command CH730 engine is warranted by Rehlko (formerly Kohler): “Three Years”, and that term “BEGINS ON DATE OF PURCHASE BY END USER.” Lincoln footnotes the Rehlko (formerly Kohler) three-year term “First owner only.” Lincoln directs buyers to the engine maker — WWW.ENGINES.REHLKO.COM / 1-800-544-2444 Rehlko Service Department.
