Massey Ferguson 375

[massey_man]

Hi all. i'm new to this site, and i'm not sure what goes on. but i've already got a question for you. On my massey ferguson 375, there are two settings for the PTO. There is the 540, which i know about, but then there is the 540E. Could anyone tell me what the purpose of the 540E is? Also, some of the lights on the dash (such as the High and Medium box lights) don't work and i can't find how to remove the cover to get at the bulbs. could anyone tell me how to do this?
