Front axle takes 4 liters of same oil as the hydrostat.
Lift front of tractor with the loader (if it has one), place stands under front frame. Drain oil, rocking the axle will help drain it.
Hydro takes 11 liters, Kubota SUDT2 personal preference for cost/quality ratio. Due to branding issues, SUDT2 may not be available, Kubota has Premium UDT available in Canada. Check with the parts guy for equivalent.
Engine is 3 liters of Diesel rated oil. Personal preference is Mobil Delvac 0W40 synthetic from Canadian Tire. My tractor gets most of its use snowblowing.
Filters are best from your local MF dealer. Some can be sourced elsewhere, but in Canada it is difficult. I've used Dan R Equipment a couple times for ordering parts.
