FWIW, I just purchased a new Kubota 3700su with FEL, Box Blade, Rotary Cutter, and PHD. Nice package deal from my local dealer. Anyway, the manual says that the 50hr service is to replace engine oil, oil filter and HST Transmission oil filter only. The fluid change out is at 400hr. Just thought I would add my little bit of knowledge to the discussion. Thanks and have a great week!
