As mentioned here the added heat and wear factors with an HST vs just having hydraulic power with NOT-transmission attachments running (a manual transmission) , makes for more frequent hst filter and oil change intervals. The combined HST and implement hydraulics in our Kubota HST tractors makes this necessary. Without the hydrostatic tranny, the hydraulic oil would last that 1000 hours, very likely.If Kubotas Super UDT 2 fluid can last way longer than 400 hrs but there worried about contamination I don’t understand why it’s not more like initial change at 400 hr then second one at 1k and 1k there after have filter changes every 250 hrs is cheaper than dumping oil every 400 hrs.As I’ve stated there behind times in this change intervals 400 hrs ridiculous !!
I would be careful about calling Kubota's recommended change intervals "ridiculous". And really, don't run the oil in your tractor 2 1/2 times the recommended change interval. If it burns out your hydraulic system well before it should, and you want warranty help, be prepared to face the music!
And your initial change comment at 400 hours is incomplete. Yes the fluid and filters are changed, but the HST and sump filter were also changed at 50 hours, and the HST AGAIN at 200 hours. Then all filtrers again at 400h.
