Could anyone clue me in on what "50 hour service" is? The only thing on the maintenance schedule in the owner's manual at 50 hours is to check the cooling system and grease the fittings... which I've done. The manual also says that the initial engine oil & filter change should be done at 100hours, then every 200.
So as far as what my owner's manual says, it isn't due yet. Maybe the 3535 is different because it's a Mahindra engine and gear trans vs the hydrostat & mitsubishi engine that's common on the other tractors?
I guess I'll give the local dealer a call in the morning and see if they've got any ideas.
