Parts just have not been an issue for me. Perhaps we're lucky or perhaps they just don't break. Other then oil filters for my tractors, I can't think of anything other then a hydraulic hose that sprung a leak. An engine oil filter for my Kubota L48 was $8.25. NAPA auto parts sells a Gold filter for my tractor for $9.00. I have heard someone say that they got a JD engine oil filter for $4.50. Not enough of a difference for that matter for most folks to make a decision on. If you go hydrostatic, you will pay quite a bit for a Kubota hydrostatic filter, but look at it, its a high pressure, machined aluminum flange that after the first initial change at 50 hours, does not get changed again until 400 hours. I recall mine was $45 but the dealer gave me the engine oil, fuel, air, air secondary, two hydraulic (the L48 takes 2 hydraulic filters, most take 1), and a HST at no extra cost. If you live in a cold climate, Super UDT will cost you about $25 to $35 for a 2.5 gallon container. Regular UDT is a fraction of that and you can in fact use most any hydraulic fluid provided it mentions it can in fact be used for the particular application. A few folks have used Amsoil synthetic hydraulic oil. Again, after the initial change at 50 hours, you won't do it again until 400 hours. You can squawk about the difference in price for filters and oil between various manufactuers, but bear in mind, the part may often times warrant the extra cost. Super UDT exceeds most all of the characteristics of Amsoil's synthetic hydraulic fluid. The HST filter is heavy and obviously, very well made. If I was replacing this filter every 25 hours of use, it might be a concern, but since you definitely don't, I'm not concerned. Rat...
