^ As Grandad4 suggests, it may just be normal mechanical noise of engine operation, but it's a good idea to check and see if you can isolate the source, just in case it's something that needs attention. A stitch in time, etc., etc. ...
I had a nickels and dimes in a coffee can sound coming from somewhere in the front of my L3240, but only at higher RPMs - up around PTO speed. It drove me crazy for nearly a week. Then, one day, I put the tractor in neutral, set the parking brake and adjusted the throttle RPMs until I heard the noise. After a few minutes with the hood open I discovered that one of the battery hold down clamps had worked just slightly loose. A quick tightening of the fastener and the noise has not been heard from, since.
The ROPS can also resonate and make some really expen$ive sounds, depending on how tightly it's clamped down. I used cable ties to secure 2 blocks of rubber from a cut up tire to the uprights; near the hinges on both sides, so the part that folds down squeezes them when it's in the lowered position - much less rattling noise from that source.
See if you can set the throttle such that the ticking occurs with the engine running, while the tractor is stopped. Then do a walk around and see if you can pin down where the noise is coming from.
A 2' length of wood broom handle makes a very good stethoscope. Obviously, you have to be careful doing this. Put the rounded end against your ear and put the other end against (static) tractor parts and you will hear all sorts of noises that otherwise get masked out by the general din a healthy engine makes.
Good luck, and let us know if you find the source!
