I have a Cub Cadet RZT S50 with a Kohler engine. It is about four years old and my yard is about four acres. It has been overheating so yesterday I pulled the shroud and the fins were clogged. They were so bad I had to remove the four metal shrouds that wrap the cylinders and use degreaser and a hose to remove the accumulated debris. I also have two Murray riders with Briggs engines that I bought in 1992 and think I have only had to remove shrouds once or twice for cleaning on them. I mow where there is a lot of cotton in the air from cottonwood trees. Is this about normal, are there any solutions? Thanks

There is no way to prevent it.

I don’t have a ZT mower but I blow mine out after each use. It’s amazing where grass clippings and tree seeds get. I have two acres and also maintain a cemetery. My tractors are a Sabre 17/42 riding and a New Holland TZ22 diesel.

My Kubota ZD-21 has a pre-filter screen, thankfully. It stops the big stuff from getting to the radiator. I just pull it out and blow the crud out of it after each use.

Here is a tip for a quick check of air flow across the head(s) and it can be done often.


The air pump and shroud system is designed to direct air across the head and discharges it downward. With the air path clean and the engine running full throttle hold your hand below each head and the ground and you'll feel the air flow coming down between the head and deflector heat shield metal. This will give you a good base standard for later checking. And it's always a good idea to remove shrouds in the spring of the season to check for mouse wintering quarters. They can be real sneaky.
