My John Deere LT155 is over 10 years old and I have tried to maintain it. I have two questions.

First quite simple: The front lens on the lights pops out while mowing, how have others secured this lens, so it does not fall out while you are mowing.

Two: What is the best (easiest ) way to clean the underneath of the tractor. The the underside of the channel that forms the main structure of the tractor. The area of the main drive belt from the motor to the transmission. I have taken the mower deck off and can get some with a putty knife and a screw drive, it seems there must be a better way that I am overlooking.
