Hi all - New poster and this might be a stupid question, but.....I致e got a New Holland TC30 with hydrostatic transmission. According to the manual, the hydraulics, transmission and rear axle share a common sump for fluid, and in fact, there appears to be only one fill port and dipstick for hydraulic oil. Based on this, I知 assuming that to some extent they also share some common mechanics and plumbing. If this is true, why are two filters necessary an HST filter and a hydraulic oil filter?
