We had a nice Saturday here in Wa, so I decided to mow the yard. While checking the oil and visually inspecting the engine of my JD LT133 I saw a mouse run out from under the shroud, then I could see mouse droppings about. I took the plastic shroud as well the metal one in front of the piston and WOW what a mess! Along with grass that was stuck between the cooling fins there was shreds of my shop rags, paper and even cat food. I put on a paper mask and safety goggles and blew it out with compressed air. What a mess. I could only imagine the results had I not seen that mouse, so just a word to the wise this spring when you begin mowing.
