    Just curious how come none of the MFG's use this engine on a Z?

    I believe Deere used this engine in the 355 lawn and garden tractor @ 18 h.p. It would be nice to see it show up in some of the smaller Z's

    Dixie Chopper used to run the Yanmar diesel. i don't think they use the Yanmar anymore. Wonder why?

    The 2V78 is used in the JD F-735
    That engine is an orphan. It has been discontinued and never really took off.

    When my Kohler 25 motors on my Gravely 260 Mowers got tired I looked at these as a replacement. I called Yanmar distributors...THE ENGINE IS DISCONTINUED.

    The engine is VERTICAL SHAFT. The radiator is on top. It theoretically would replace a gasser 2cyl aircooled.

    I have gotten the impression from the distributors I talked to that Yanmar is on the skids right now (the whole Japan economy is).

    They had a good product but did not follow through with the proper marketing and support for the engine.

    If you look through the Yanmar website it just gives you the feeling something is wrong. There is a lot of out of date information. It looks like Yanmar is rather disconnected and out of touch, sort of swooning, just getting by these days.

    Dixie Chopper is reported to be having problems on warranty issues with Yanmar. I understand that is one reason they phased out production of the smaller, 26HP, diesel machine.:confused:

    Yanmar's site has ALWAYS been a boondoggle.

    I don't think they're hurting.

    I do think the V-Twin is an oddball, and will or already is discontinued.

    DC modifies Yanmar diesels to run higher RPM's then they come from the factory. Matter of fact DC has done that for years on all their engines.

    The 26 hp was a DOG when if came to power. It's hp listing was no where near 26hp as stated by Yanmar. Just like the 50hp isn't really 50 hp.

    I really think the future is in Diesel powerplants. Things have come a LONG way over the years. The major problem is weight. Most diesel engine blocks are cast iron, where MOST gas engined mower blocks are aluminum. BIG difference in weight.

    Yeah, that's what made me think of it actually. Every week I see this little ol' lady just a whizzing around her yard on a diesel Deere.

    Lastnight I was flipping through some of the old literature I collected, looking at different brands of 60" ZTR's and ran across something. Bob-Cat actually does use the Yanmar Twin as their diesel engine. I missed that detail before.

    I had that diesel Bobcat for a demo one time a couple of years ago. I thought it was underpowered with the 60" deck. It was also VERY loud. It was so loud, that even hearing protection eas not doing a good job deadening the noise. I was not impressed with that Yanmar.:(

    Rumor mill is that we will see the Kubota line show up in the Dixie's in the near future.. This was from a very good source--Local rep.

    The Yanmar V-twin should have been a great engine. Yanmar tests their new engines to extremes and the engineering was state of the art for small diesels. I agree that they failed to market the engine properly. I have wondered if the lightweight construction--about 125 pounds with radiator--was pushing the limits for weight reduction.
