I know is an air cooled maybe for a walk behind or even a stand on mower maybe some of you guys might say is china garbage I was quoted 850 for a 20 hp I think their horsepower ranges are between 14hp and up 25hp what do you guys think?

Turbocharged too!

You wouldn't have the first diesel WB, Dieutz (SP?) made one some years ago. I'd heard that it was heavy and the oil pan was too shallow to allow it to handle slopes.

I don't know a thing about the motor you pictured. I'd really be interested in your evaluation. I've always wanted a good diesel WB to round out my fleet of mowers.

I wouldn't dismiss it immediately as China crap. However, no way I would buy it. Too much worry of the availability of replacement parts. I spoke with
Mr. Wright himself of Wright Mower at the expo in Louisville in October. Yanmar made a two cylinder diesel engine for a limited time and Wright was gonna put it on a stander. However, Yanmar discontinued the engine before he could get it rolling. I am a huge fan of a diesel engine. If I could find a stander with a diesel engine, I could sell three mowers and buy one.:walking:

I see you have a 2002 60" Kubota ZD-21 diesel how do you like it?

I am thinking in buying a Grasshopper 321D-48:cool2: witch I believe it has the same Kubota Engine. is that right?
I have never had to do any work to either one of my Kubota engines.

Grasshopper uses the "industrial" duty versions of Kubota engines. Kubota was using the "farm tractor" version of their engines. I am not sure if Kubota is still doing this or not. The industrial versions are just a little heavier-built engines, that are used primarily on construction equipment.

Does the Diesel fuel have crap in it? or why every Diesel Engine out there have these nice fuel filters?
A fuel filter for my Duramax is $45 while a set of injectors is $6,000

It ain't hard to get dirty fuel, especially when you buy it where we do like at gas stations with a diesil pump out back.

Your signature is kind of funny, "Don't buy air cooled crap, get diesel." Then your thread talks about air cooled diesel.
The leader in air cooled diesel is Dieutz. Mounted to their tractors they're not too noisy. But I tried out a 72" Gravely with a Dieutz motor. They didn't use isolating motor mounts, sound baffels or Dieutz muffler. The noise was literally unbearable! Something like combining a rock chrusher and a jack hammer! Especially when you got it between two buildings.

That's what I'm wondering about your Chinese diesel. Does it clatter like a Yanmar? We have to take this equipment to customers properties and some ain't going to like the noise.

diesel's have such fine injectors and operate at extremely high pressures, especially the newer common rail motors. mine runs upwards of 25k psi fuel rail pressure. it doesn't take much at those pressures to damage something. filtering down to about 3 micron absolute is cheap insurance against injector and pump wear, as stated above injectors are very expensive.

I am aware about the common rails, with pleasure around 2,000 bar (36,000 psi) and five injections per combustion cycle helps with fuel economy. I know kohler KDI have these cool little things these 3 and 4 cylinder diesel Engines with a common rail and a turbocharger up 56 horsepower with a 3 cylinder
