Mitsubishi 2000 has no power

I am posting for my brother in FL. He bought a little Mitsubishi 2000 diesel with a 6ft finishing mower and it barely has enough power to run it when you drop it to the grass. It's a 2 cylinder rated at about 25 hp he said. Has 3pt and pto and starts easily with a bit of ether but lacks power. Anyone ever have one of these and had a better experience? The fuel filter is like an old gas tractor with the screw on sediment bowl on the bottom of the tank and no real filter like most diesels have so changing that doesn't seem like the answer. Any help will be appreciated.
 
Do you think that these little tractors can produce enough power to run a mower if everything is right? Or is the lack of power a normal feature for them? Thanks for the reply.

For one thing, I wouldn't trust a sediment bowl alone for filtering with a diesel. Injector pumps and injectors are tight tolerance devices, and even small bits of contaminants can play havoc, but you probably already knew that. I find it hard to believe that it doesn't have a real filter (or two), somewhere.

Second, at what temperature does it require ether? We're talking Florida, right? If it can't develop enough compression to heat diesel to ignition at 40*, it's probably worn out. That "25hp" is more like 15, and that split between the mower and the rear wheels.

As a reference, my beat nearly to death Massey with a Perkins diesel, will start at 20*, without glow coil, block heater, or ether. A neighbor's Ford 4000 needs half an hour with a block heater below 35*, but it's about fit for pulling hay wagons, in low range. Their 6600 will start at ~20.
 
Thanks for your detailed reply. That's sort of what I was thinking too. I didn't hear it run but when my brother said he had to give it a little shot of ether that led me to think it must be weak on compression. I did follow the diesel line though back from the little injection pump to the sediment bowl that is screwed right into the bottom of the tank. I thought that seemed very odd so unless it has some place inside the pump itself, (which I think is highly unlikely) then it has no "normal" type of filter on it. I was expecting either a screw on filter or one with a bleed screw on top of a canister or something but it isn't set up that way. Maybe some idiot removed it before he bought it. It looks like a nice clean little tractor and he says it sounds like a little John Deere with that 2cy engine but just can't power that big mower so I told him to advertise it here and maybe find something big enough to run that nice finishing mower.
