Hi, my name is***** will be assisting you.

Based on information I have found through Kohler the replacement will be a CH23S-76528. It is being shown as a direct replacement for you existing engine.

The replacement number you gave me is showing on several websites that it is no longer available.
Customer: replied 1 year ago.
do you know a website that I can view & purchase one from? Kohler website shows this number as being retired.

I found a place that indicates that they have one in stock, but only one as long as no one else places an order before you would there is a chance that you could get it.

http://www.lawnmowerpros.com/detail.asp?id=PA-76528 Told me by phone that they have one left in inventory.

http://www.sourceapart.com/index.php?route=product/product&product_id=1320057 They show it to be discontinued but will still allow you to order.

https://usenginescorp.com/shop/index.php?id_product=320881&controller=product Also indicated last item in stock

See if any of these help you. I am going to continue to work to see if I can find anything else as well and will post back here if I find anything.

I have found three other engines that may work on your machine based on crankshaft size and length. They are all three made for John Deere mowers.

CH640-3134 20HP

CH680-3091 22.5HP

CH730-0169 25HP

Any one of these can be purchased through http://www.smallenginewarehouse.com
