Art, back it up! The example I gave above are both liquid cooled and as close to apples to apples as I think you will find. Philip.
Lets try to compare apples to apples. Both Kubota engines. Both naturally aspirated. Both nearly same displacement.
Kubota WG972-G-E3 gasoline engine. 962cc. 32.5 peak hp @ 3600 rpm. 55 peak ft-lb @ 2300 rpm.
Kubota D1005-E3B diesel engine. 1001cc. 24.8 peak hp @ 3600 rpm. 41 peak ft-lb @ 2400 rpm.
Fact, same displacement, gasoline makes more torque and horsepower. Peaks are about same rpm.
You have to add a turbo to make a diesel a torque monster.

Ok everyone, thanks for all the good advice and feedback. Now down to the purchase. I have decided to go with the bx2360 60"MMM and front mounted blower with hydraulic rotating chute. Price quoted from dealer is $15,000 any thoughts?

I think if you looked at torque curves at lower RPM's, this is where you will find a diesel outperforms a similar gas engine. When you overload a gas engine, say when mowing grass that is too long and your going to fast, it will drag down, get below its torque peak, and start to die out. With a diesel engine, it will drag down also, but still have good torque and continue to lug along and not die out as easy.
Look at the torque of both a gas engine and diesel engine at say 1500 rpm, and this is where a diesel will outperform a gasser.
From personal experience, I had a gas mower, about 700 or 750cc in size, 25 hp, 54" mower deck. I now have a Kubota, 900cc engine size, 25 hp, 60" mower deck. There is just no comparision between the two, the diesel pulls much better, but it is also a larger displacement to make the same horsepower.
The truth is, its tough to compare a diesel and gas engines, its the proverbial apples to oranges comparision.
