    We had a ferris with this motor on demo for a few days (61in deck) and it felt a little underpowered (in comparison with a 28hp kubota on a grasshopper).
    I don't know that I'd pay extra for it over the 25hp kubota currently offered.

    We do have the bigger brother cat motor in a skid loader---31.5hp with an extra 500cc or so and it does ok. Probably great on a 60-72 inch mower.

    The problem with the cat, is that the yellow paint makes it more expensive than it really needs to be. I also wonder how easy a scag dealer can get parts for a cat engine... KLC99's right in that a 28HP Kubota on a grasshopper will out perform just about any diesel on any other mower. Grasshopper dealers will tell you that Grasshopper is not a "parts line". This means that they don't make tons of money selling replacement parts for the machines. Look in any after market catalog in the Scag section... They haven't done any improvements to their hydro systems.

    Buying any brand mower equipped with a CAT engine, is just asking for trouble. I don't think I am wrong when I say that NO mower dealer selling these CAT engines is allowed to do warranty work on the engine. Nor are they trained/qualified to do anything with the Cat engines, other than an oil change.
    You will have to take your mower to a Cat dealer to have the engine repaired if needed. How close do most folks live to a Cat dealer? The Cat dealers nationwide, as a rule of thumb, are very busy repairing the construction machines they sell. They could care less about getting around to fixing the engine on a little old mower they did not sell. Ferris is having trouble getting engines fixed on their Cat-powered machines in some places. Notice how Hustler is NOT offering Cat engines anymore? There is a reason for that decision. Part of that reason is lack of support from Cat
    I would not even consider buying a mower with a Cat engine. You really need to check out mowers using Kubota diesels. There are lots of Kubota dealers to fix the engine if needed,and, many dealers selling Kubota-powered machines are authorized service centers for those Kubota engines.
    Kubota is by far the best choice of diesels for use on commercial ZTR's.

    Mowingman is right. Besides, a diesel engine on a ZTR is overkill anyhow. Pay too much for what little fuel efficiency you will get over a gas engine. Of course the diesel will last forever, but how long will the rest of the machine last you? There is a point around 1200-1500 hours when it is no longer viable to run a ZTR commercially and that won't change with a diesel engine. Unless you really need a lot of power, I would just go gas and forget diesel.
