I have used both kubota filters and wix. They both work fine but the price is not much different The biggest savings can come from your fluid. Tractor supply sells their premium udt that meets kubota, deere, new holland specs. You can get 5 gallons for $39. Neither deere nore kubota makes their own oil and as long as meets the warranty specs you will be fine. I have used their fluid in my 2 kubotas, massey and new holland tractors for the last 6 years with 0 problems.
I believe Ashland does Kubota fluids/lubricants.
I forget who it is, but its not Ashland. Kubota sued Ashland for claiming compatibility with SUDT and won.
I don't think engine oil filters are much of an issue, as very high quality oil filters are made by FleetGuard, Hastings/Baldwin, Wix etc. I'd never be concerned about those. They are likely better than a Kubota, frankly.
But the trans filters are so "custom" and I've never found any other option than the Kubota. That's fine, because it doesn't get changed THAT often and it seems to be quite unique, often times with magnetic rings, etc.
They're kind of niche and there isn't likely a big enough segment for the big filter companies to bother with.
OK i got the filters from Napa today and the oil from my dealer. They gave me UDT oil When i check the owners manual it says to use UDT when I look at the shop service manual it said to use Super UDT.
Then I look at the engine oil requirements the owners manual said to use 15w-40 the shop manual said to use 10w-40 . witch one is right ? Will the shell Rotela T oil be ok?
Then the question of oil type there are different ratings in the manual for a external egr valve versus a internal egr valve .
This is a M7040HD-1 Tractor the engine has a turbocharger .
Thanks for any input the owners manual and shop manual have different requirements on every thing
This is the 50 Hr service The hydraulic was just as clean as new some sludge on the magnets , the engine oil was a little dark but the front differential oil was very dark. I will replace this again in 50 hrs to keep a eye on it .
Thanks for all the replies and recommendations

The hydraulic oil will generally look clean even after a long period of use. Sometimes the wet brakes will add color but not much. There is no carbon from ignition to darken it.
Engine oil in a diesel gets dark almost immediately. Trust the hours rather than the appearance. The special additives extend the service if good oil is used.
The front differential oil shouldn't be that dark. Kubota puts in UDT but most folks in the know replace it with 80-90 gear oil in the lower 48 (maybe not Minnesota).
The manual way overstates the amount of oil to use in the front differential. I think they list the gear case and the differential as separate units. In fact, it is all one reservoir. Two gallons of gear oil will be plenty with some left over. Then you'll be good for another 600 hrs. No need to change it again in another 50 hrs.
