L3901

2018 l3901. 469hrs. Always inside. Today goin down the road 2500rpm ish. I hear a small knock that becomes quite noticeable. I slow up head back to yard. No codes. Shut off a few times and start still there. After bit of putting around noise fades to only higher rpm’s 2000 plus. Now it seems to be back to normal. Im figuring an injector gremlin ? Any thoughts. Thx for any insight.

Water in fuel?

Any sense of when it started, if the tractor happened to be headed somewhat downhill?

Thx for the guesses Ha Ha. Fuel and oil good. Flat road. I guess the knock wasn't a fast like high speed knock/rattle. It kinda stayed constant but got louder with an rpm increase. until is slowly went away. I'm away from the tractor for a few weeks but when I get back hopefully there is nothing more to ask about. Ha Ha Thx.
