That ad does not claim the hours are correct. It says hours shown on the hour meter. I will note that something sounds bit odd in the video of the Deere in question. I can pick up some ticking sounds that likely should be picked up on the camera microphone. I always have to question an add that does not show any close ups that might answer any real questions. Undercarriages should show idler positions, sprocket teeth, bottom rollers and any leakage points like sprocket seals, pivot shafts and equalizer bars. A photo of the cab and close up of the monitor panel with the key on engine running. A photo of the seat and cab upholstery would be nice. Photos of the implements should show the underside corners of the blade, close ups of the blade joints and ripper linkage joints. Photos should also show what is right about the machine as well.
If you want to sell it over the internet and maximize sale price, you need to provide some real information.
