That series of Kohler was basically a good engine, so I would take a serious look at rebuilding, depending on what parts you will need and their cost. This manual will help you decide if you think you can do the work yourself. I would price out the parts you figure you need and add $100, in case you forget something. Might mean a tear down before deciding. http://resources.kohler.com/power/k...45.1658754340.1601335970-986432130.1601335970

The only issue is the labor. I just went through this with my CV15S when I considered having the valve work done. A head gasket job is $20-50 in parts but $360 in labor. The extent of the damage described sounds like minimum 6 billable hours plus parts which will near $800.

With the KT-725 engine, can you easily change the head gasket and push rods without removing the engine? I assume that is a pretty easy repair, especially if you don't have to remove the engine. I assume you need to remove the muffler. How hard or easy is that?

If I am going to repair, I will do it myself. Also, if I have to replace with a new (rebuilt) motor, I would do that myself. That appears to be almost trivial since I think there are only 4 bolts mounting the motor on the mower. I think I can get the motor, myself, for about $1300. The shop wants almost $1600 for the motor and about 4 hours of labor.

Most likely it's an AIR Cooled engine.... The flywheel has a fan that blows air over the cooling fins on the heads, if enough grass and debris gets built up it will hold heat and/or block air flow.
Think I've heard of this before.

Funny how a 10 minute yearly cleaning procedure can later cost thousands of dollars.
