Default Smoking 3204

My 2002 cub 3204 has a kohler 20hp motor. Hour meter shows 570 but thinking it may be 1570 not sure.

Smokes at initial start up. After I mow an acre and idle down it smokes really bad and continues to smoke at idle.

Any ideas and help would be much appreciated.

What color is the smoke? Are you saying it does not smoke at all at WOT, only at idle?

I guess SOP in that situation is to pull the heads and check for ring wear and blown head gaskets. I'm not familiar with the Command engines but I remember reading somewhere once about a valve that can clog and cause oil to go into the cylinders through the carburetor or something like that. Maybe someone more experienced with these engines can chime in. But with that many hours on it you may want to pull the heads and remove some of the carbon deposits, check the valves and put in a fresh set of head gaskets anyway.

No compression or leak down test. Was reading about the breather reed causing oil burn. Thought that just let air out of the crank case.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
