    The Briggs will suck fuel compared to the Kohler EFI. I have a 26EFI and a 28EFI. They are both smooth running engines that sip fuel (< 1gal per hour). The EFI makes them incredibly responsive. The engine reacts instantly to load, unlike a carbureted engine that will have a lag as the governor tries to open the throttle on the carb. Once you have an EFI engine on a mower, you won't go back to a carb. Given a choice, would you go back to a car with a carburetor? I certainly would not, and this is no different. My 26EFI has well over 2500 hours without so much as a hicup. The 28EFI is much lower hours at <1000, but also trouble free. No choke to fiddle with, just turn the key and go. The Bosch fuel injection system is very similar to that used on many cars.

    So I agree with an earlier poster who said this is a no brainer - go with the EFI. You will never look back.

    Those who say EFI are complicated and hard to work on, have obviously never owned one. Remember all those who said fuel injected cars were bad, complicated and hard to work on? Yup, that's right, they are all driving them now, and the cars couldn't be more reliable!

    I believe the Briggs would seem much more powerful because of the sheer displacement and torque. It would be handy on 10-14 day accounts or other heavy growth. The 28 efi would probably pay for its self in a few hundred hours with more than adequate power for most. Just my 2 cents. About 50% of my accounts can be very heavy and the 27 Kohler can handle them but there are times when I could use the extra hp/torque of the Briggs. Both the 28 efi and 31 are available on the 07 regular Lazer jfmx345. I sure can't see either going for less than about $9,000+ but I've been wrong before.

    That's a tough choice. I've used the Briggs and it's a beast. I would have to say go with the 28 EFI just simply because of the great fuel efficiency of them.

    Get ALL the facts....

    Something is wrong with the info your getting.

    The 28EFI is a standard Lazer.

    IF the other DOES have a 31hp BVG, it IS an XS.

    You get a heavier-duty frame, bigger pumps and wheel motors, faster speed, and with all that, higher price.

    These two models were never close enough on price to be equal.


    Report back and tell us what he is really offering.

    According to the dealer, there was no acual "XS" in 2005. He said that both of these mowers would be equivalent to the current XS model.(larger pumps etc...)

    I may have to take a run over and look at these units to see whats what...

    For 07 the 31 will be on the standard Lazer and the 28 always has been. I guess your refering to the guy that thought the 28 was on an XS. It would be a hard decision for me to choose the 28 efi or the 31 on the standard Lazer. Extra power, torque, cubic inches or good power and fuel economy. I think the list price on a 31 regular Lazer starts at about $10,300. So you should be able to get it in the 9's.
    Here are the engine combo's for the 07 regular Lazer (not XS)

    LZ23KC605
    23 KOH
    60" Triton (152 cm)
    LZ27KC605
    27 KOH
    60" Triton (152 cm)
    LZ28KA605
    28 KAW
    60" Triton (152 cm)
    LZ28KA665
    28 KAW
    66" Triton (168 cm)
    LZ28KC605
    28 KOH EFI
    60" Triton (152 cm)
    LZ28KC665
    28 KOH EFI
    66" Triton (168 cm)
    LZ31BV605
    31 BVG
    60" Triton (152 cm)
    LZ31BV665
    31 BVG
    66" Triton (168 cm)
    LZ31BV725
    31 BVG
    72" Triton (183 cm)

    The 31 Briggs will not be offered on the XS for 07. Not sure if we are on the same page or not TLS. First year the 31 has been offered on a regular Lazer so any previous 31 Briggs would have been and XS.

    OK, here is the real story...

    The Briggs engine Z is the XS model...
    The EFI is a regular Z.

    So here is the deal
    '05 Lazer Z
    28efi/60
    Ultracut

    or

    '05 Lazer Z XS
    BVG 31/60
    Ultra cut

    Both same price.
    Which do you buy?

    Thanks for the help
