I can't believe it. My old grasshopper 720K with a Kohler CH 20 S finally died with 2460 hrs on it. The problem is Kohler is not making this engine for at least 3 more weeks, or longer. No engines are available anywhere with this spec number accept Grasshopper. This engine normally retails for $1400. But Grasshopper will sell it to me for ONLY Get This .....$2300. plus shipping. What a rip off. So anyway I said No Way ! I found a new 25 HP Kohler that will work with just a few modifications by a reputable Kohler dealer. But it will still cost about $1900 an change, but they are providing the labor to remove and replace the engine. They have already done this to another Grasshopper this yr with great results. Has anyone else run into this? Sorry for the long post just needed to blow off some steam!!!
