Fernbank,
That's an interesting question and I never could find an
answer from Kubota or ANY dealer.
It's all opinions.
I have a
L35 with GST trans. Book says use SUPER UDT.
Many dealers use UDT saying SUPER is not necessary in my
climate (mostly 40-80).
A few dealers (I called around) said use only SUPER because that is what Kubota says to use.
Kubota would only say USE WHAT THE BOOK SAYS and not discuss
why their own dealers are not advising that. I also brought
up the warranty issue using the wrong oil and they said CONSULT YOUR DEALER...DUH.
Technically the UDT is useable in a GST in my climate as it
is rated for these temps I think UDT predates SUPER.
I found my own answer in the fact that my loader operates
noticeably slower with the UDT then the SUPER.
I also figured that with my frequency of short jobs, even
though air temp outside was not too cold, the unit would
shift and operate the hydraulics better with the SUPER
which is what I am back to using. (speaking of short jobs,
I ran into one fellow that uses a dipstick heater in his
tractor so it's always closer to being ready to go)
Actually for all around use I'd like to mix SUPER and REG
50/50 but I don't think that's advised. I haven't asked
dealers or Kubota, I don't have my mind right at the moment
for the variety of answers I'll probably get.
As to work done yourself I'd suggest keeping your receipts
for your filters and oil at least, and a good logbook. Be
specific in your listings on what happened at what hours,
it will make you look like you're obsessive-compulsive about
your tractor if they start to argue with you and they'll
back off /forums/images/graemlins/wink.gif
How can they possibly fight you on any warranty issues when
their own dealers don't follow their (Kubota's) oil specifications and change intervals?/forums/images/graemlins/crazy.gif
I've spent time on the other side of the parts and service
counter in my life and under a few cars on hoists so I like
to think I'm open minded about this but it seems to be getting
harder and harder to find a mechanic I'd trust. They're out
there but they are hard to find.
I hardly ever let anyone work on my stuff, sometimes wife
gets on me to do something I don't have time to do or hoist
is blocked. My record letting stuff get done is not too good.
Careless mechanic dropped Tahoe off of hoist at GM dealer.
I was rather amazed at how fast he got it positioned on the
hoist, takes me about 10+ minutes to be happy in how something
is mounted, and this is my own stuff I do all the time.
Was really cool seeing our brand new vehicle come off one
corner and have the front end 20 feet in the air.
The most shocking part... I swear on a stack...When it fell
NOT ONE OF THE OTHER MECHANICS EVEN LOOKED OVER! Huge noise
and no one stopped what they were doing. Must have been an
everyday happening!/forums/images/graemlins/frown.gif
A Ford dealer mechanic let all the intake manifold gasket
material go down into the oil pan which of course filled
the oil pickup screen and pump and lunched the engine.
Then the simple things, finding an oil drain plug has been
rounded off by pliers, seeing my daughter drive in with the
skidplate on her truck hanging down...
Even if you aren't doing the work yourself, try to become as
educated as you can about what should be done and check it,
or ask a friend for help.
I don't profess to know everything or even anything but I
can sure tell when a grease fitting hasn't been touched.
dig on...
