It’s a 2653a John Deere. I am thinking it’s possibly trash because with the throttle fully open, it runs like it’s half open. No sputtering or anything just sounds like it’s in a bind when I try to go foward wide open or put reels down and on trying to mow. It’s like a load makes it lose power.

It's a fuel supply issue. Change fuel filters first.

Not going to dig way into this but with a diesel, it's either lack of air, lack of fuel, or lack of throttle. If it's lack of air, it will black smoke it's arse off. If it's lack of fuel, it has no power. Yours isn't getting fuel.

That's an interesting looking mower, I've never seen a 3 wheeled version like that before not to mention diesel. I'm curious why they were diesel and not gas? I don't have a damn thing for help sorry. I would check your fuel lines though I've had connections go loose and bad lines before and it seems like a carb (I know not on diesel) or fuel supply issue.

Put a load on it by driving up a hill or pulling your truck down the driveway.

If it doesn't bog down, there's something binding up between the engine and the blades.

If it does bog down, it's fuel related as others have stayed.
