    Do any of you have this problem? On cold mornings sometimes when I try to engage the blades the mowers bogs and goes dead. If I let it warm for around 3-4 minutes it engages fine. Is this something I shoud worry about or just blame it on the cold? By the way Im in North Carolina so its not that cold yet.

    Thanks and Happy Holidays!!

    that happens sometimes with me. I usually let the engine warm up a bit, and then engage them. After a while they are fine.

    Probably just a cold natured Kohler paired with a low hp to deck ratio. What RPM are you engaging at?

    Yup, they are going to do it, the belts are cold, fluid is cold, and the engine is not at operating temperature.
    it is harder on a engine to put a load on it before it is at proper operating temp.

    Thanks, I engage the blades at full throttle and it is a 20 hp kohler with a 52 deck. I will have to let it warm from now on. Thanks for the quick reply.

    Personally, I can't engage in much work:sleeping: until I've warmed up to a few cups of coffee. :laugh:

    Try starting the mower at home before you leave and letting it run for 5 minutes while you get other stuff ready to go. That way when you get to the jobsites, you won't have as much downtime waiting for the mower to warm up.

    20 HP Kohler is a lot of engine for your deck size.


    It is really hard on the clutch and belts. Similar to dumping the clutch in a car at high rpm, in my opinion.

    Try a little throttle, about 1/3, then put the choke on about 1/2 way, then hit the blade switch, then take the choke back off.

    This trick works on my Kohlers. On our Kawasaki, same trick, just use idle throttle and full choke.

    Play around with it, the find the amount of choke that works best, and use as little throttle as possible to preserve belts and that expensive electric clutch.

    that is exactly what I do to. After that first start while loading, and letting it run for a good 5 mins, each job site there after starts on the first pull and is ready to go
