I have the 3040, the bigger brother to yours. It recomends oil and filter every 100 hrs, fuel every 400, hydraulic filter only at 200 and every oil at 400. I personally change the oil and filter every 50, the fuel filter at 100 and follow recomendations for everything else. I find that while brush hogging I need to change my air filter every 50. There are few 2740 and their farmtrac equals on this board, hopefully they will chime in.
