    How much longer does a liquid cool last more than an air cooled? Is it worth the price difference?

    don't have figures, but liquid is the way to go , for sure.
    heat is the enemy of HP. You can have a much more reliable and higher performance engine with liquid cooling.

    I have a LC Lazer Z. The longevity is pretty substantial... as mention above the run much cooler than the Air Cooled. They also are a lot quieter than the Air cooled....

    From what I have heard they last at least double that of an air-cooled. Then jumping to diesel doubles that. That's why I bought a diesel.

    I got into the same conversation with sales reps from various manufacturers when i made my last mower purchase. A few years ago the liquids beat the air's hands down. With todays engine technology the airs are lasting much longer and the liquids haven't changed much. I personally went with air cooled on the last few scags i bought. They all have the kohlers on them. I also like the kawasaki's, i believe they are both good long lasting hard working engines. I will save the extra $1000 i would pay for a liquid and add it to another new mower next year.

    The numbers I've heard are 300 hrs. for a air cooled and 6000 for a liquid. I have a liquid Kawi and I don't think I would buy another one. I just think for the extra money it wasn't worth it, plus I like rotating mowers out of the fleet about every 2000 hrs. And also here in Minnesota we don't get the extreme heat so there is not as much need for the liquid. Don't get me wrong it has been a great machine. I just don't think I would get another.

    a good point that JK makes is thatwhile they do last long in order to reap that benefit you would need to keep it a long time....

    I bought a LC because I got a leftover 04 for a little less than a 05 air cooled.. I wouldnt have paid the extra money for the LC I just got a good deal.... They are considerably quieter which is a nice feature

    All the engines we get are air cooled Kohlers and we have had excellent results from them and thats all we'll be buying from now on. We don't put enough hours on our machines to need a liquid cooled.

    I run my Scag for 9 hrs straight on some days. I've had it for 4 yrs now. I don't know if it would still be as good if it were air cooled. I'd go liquid cooled if you can afford it.

    The weight and cost of liquid is not worth it to me, just use mobile one and don't worry about the heat and put the money you saved in your pocket!
