    Well I am going to the more crew friendly Exmark type mower... Hustler. What would you guys buy a 27 carberated kholer, 28 efi kholer, or 27 liquid cooled kawasaki? I am planning on keeping it for two years or 1000hrs and selling it or retiring it. What engine would you get? BTW I have already done a search, just want more input.

    They have more torque and run cooler. That EFI sounds like a good idea with better fuel consumption but i dont know much about it and i don't know anyone with one.

    I have the 28efi, and demoed both before buying the 28efi. The liquid cooled would be better for the long haul (more hours) but if your selling at 1000 hours. You would be fine with the 28efi, the efi also uses about 35-40% less gas than a carborated 27. The efi pays for it self very fast. My vote is for the 28 efi.

    The extra electronics with the EFI worry me in the dusty environment in which these mowers live in. Same with the radiator on the liquid cooled 27. Also the liquid cooled 27 has that many more parts and things to check for a crew to be using. My vote is with the carburated 27 kohler. I have one on my Exmark and it has plenty of power. I feel it is the most reliable.

    I had a 25 kaw for a year and sold it with 475 hrs. Loved the motor till I tried a 27 kohler. Kohler has more torque by far. Only 100 bucks more. EFI really wont pay for itself in only 1000 hrs. All are good motors but have heard alot of bad about efi on all mowers, not only hustler.

    Alright so the liquid cooled will last longer. The EFI will get better gas mileage. Anybody have an idea what the difference in gas per hour is? Is the liquid cooled easier on gas than a regular carburated engine?

    The estimates I heard were about a gallonp/hr efi and 1.2 carb but that was a 25 carb vs. 26 efi before kohler jumped up the hp. As far as efi's not being reliable, I am on my third and fourth efi mowers (had two 26's ,just bought two new 28's) and have NEVER had a efi related problem. Espesially if you will trade every thousand hours or two seasons reliability shouldn't be an issue. I absolutely love my fuelies, even tried going back to a carb a little while back, sold it after only 255 hours, it would sit on the trailer while the efi got racked the hours up. I haven't had a liquid so I can't give a fair comparison but I think you can tell what my vote is.

    eXmark and Walker had "problems" with early ( '97 or '98) EFI engines because the MOWER manufacturer grounded the engine's electronics over paint, not to bare metal. Once they corrected this screw up, they had no other 'common' "problems".

    The problems were never with the Kohler EFI engines, but were installation problems.

    Go with the EFI. 2nd choice the 27 Kohler.

    My Hustler SuperZ 28EFI is great on fuel, 3/4 gallon an hour. But even without the fuel economy it's worth having. The engine has the smoothest, most efficient power output imaginable. You just won't have the bogging, or RPM loss when it encounters heavy grass, it adjusts instantly! It really is an amazing engine.

    The liquid cooled involves a whole lot of things to go wrong ( radiator, hoses, pump, leaks, clogs, leaks, BREAK downs!). If your mowers will run 5 hours without stopping (such as highway right-of-way mowing), it may be of value. Still, I ain't a believer in liquid cooling on a ztr, too much to go wrong.
