    Hi everyone, I need a new machine to add for this season and have decided on a Walker. I have previously ran Scag & Exmark ZTRs w/ baggers, but plan on a Walker GHS and my 52" Scag TC to side discharge for regular setup for me and my helper.

    Is it worth ~$13,000 for the MT26EFI or is a MT20 or MT23 sufficient. Price difference is a concern but I am more concerned with EFI issues (check engine lights etc) where most everyone can work on carburetors in the field if needed.

    Thanks for your input

    If you are only going to mow, the MT20 or 23 is is fine.

    I found the 20hp a little lacking on some of the attachments and bigger decks

    But if you want to run a 74" SD deck occasionally or the broom or snow blower, or want an engine that will last past 2500 hours and you are going to use this machine day in day out, 26efi is worth the extra investment.

    Carb vs. efi.

    Fuel, air mixture is hardly ever the problem with a small engine.
    you just won't find your self constantly tinkering with a carb to "make it work"
    so your worry about being able to work on a carb is moot.

    I now 2 days a week about 20 accounts. I'd eventually get maybe a 60" SD when my Scag gets too old. I have never changed decks out but hear it is quick and easy. I think I'll just go EFI seeing the 23 isn't much a savings.

    We had a 99 MT 48 GHS 25 Koehler. Bought it brand new. Last yr it turn 4500 hrs on the original motor before it blew up. If you take care of your equipment and do regular maintenance then there is no reason why the motor won't last. I found the 25 hp to be just fine when running a big side discharge deck. We have a 54" deck that we use to mow cemeteries with.
    I haven't run a EFI machine so I can't comment on any saving in fuel. I personal am not a fan of all the electrical crap on the mowers now a days so I personal will stick with carb machines.

    I have a 26-27 hp efi Kohler on a Vantage and a 23 hp Kawi on a Turf Tracer. The efi engine seems to use about 10-15% less fuel even though the mower is 300 lbs heavier and the engine has 3-4 more hp.

    One thing though, when I got the Vantage the engine was running 3400 rpm. After I had it adjusted to 3600 the fuel consumption increased several tenths of a gallon per hour.

    EFI rules harder than Roddy Roddy Piper!!!!!!!

    Oh yeah, I am obsessed with Walker too!

    Go with the T25i.... You will not be let down...

    The new T25i's have the Delphi system now, closed loop..... no worries

    Now I have heard mixed info about the Delphi. I kinda want to buy one of the last Bosch just because it is proven but I need to sleep on it some more.

    Other than the power plant are the MTs all the same machine just with a choice of motors?
