What maintence should I do on my tractor after the initial break in? I am planning on changing the oil, checking air filter, greasing all the zerks. The manual says to change the hydraulic/transmission fluid and filter as well as the front axle fluid but my dealer said not to worry about that and just change the oil. Should I change these as well or just worry about the oil? I don't mind changing these if need be but don't want to bother and buy 10 gallons of fluid if not necessary.
