another Kubota UDT vs TSC premium hydro fluid?

[DieselPower]

That's very true. The oil itself only plays a very small part in how well it performs. The major differences come in how it is blended. Higher quality lubricants can have 4 to 5 times the additive package level when compared to a low quality (cheap) lubricating oil.

I just did my 50 hr fluid changes on my GST 3130. Two dealersd said to use only the super UDT for the tranny and rear differential. They said you could use regular gear oil or Regular kubuta UDT for the front axle and that is what i did. Also have to remember the wet brakes....After payiny good money for your tractor what's the difference of a few more bucks for the Super UDT if they say it's really needed. Why take the chance? I had a lot of crap in my hydraulic filter after my 50 hr maintinance.

Hey guys since it is going to get hot soon I thought I would bring a post that was started last summer.

http://www.tractorbynet.com/forums/kubota-owning-operating/83241-b7500-hst-power-steering-3-a.html

There is other good Hydro fluid out there that will protect better in hot weather.

I used to run Super UDT until I figured out what was causing my problems.

My tractor is fine since I got rid of Super UDT.

The larger Kubota's have better oil coolers for the Hydro Fluid Than the B series tractors. I believe this makes a differance and Super UDT seems to work fine in them.

Super UDT and Chevron Synthetic All Weather THF work great in cold weather.

If any of you have steering or lift problems in hot weather spend some time reading the post I posted above.

A while back I recieved emails from two other B series tractor owners that had the same problems I had and thier problems went away when they switched to a full Synthetic Fluid.

I am just want to inform us tractor owners about a problem that could develop in HOT weather.

Just keep this in mind.

Be safe.

The only UTF that meets SUDT specs is the Chevron Synthetic ALL weather UTF.. Believe what you wll but the specs are there for a reason. Don't be cheap and ruin your equipment. Hydro's and Glide Shifts are mostly impacted by not using the correct fluid.

The extra few bucks you spend over the long run should give you a sense of security so to speak. After the initial investment why take a chance with unproven hydro fluid instaed of the hydro of choice, super UDT for the application. If I heard from an owner who used an off brand instead of sudt in his GST for 4000 or so hours and had no problems. Then I'd switch.

Chevron Synthetic All Weather THF is the only Hydro fluid that has a Super UDT spec. and it is good stuff. It fixed my steering and 3 point lift problems. as I wrote in the fourm I started. Take time and read what I went through.

It holds up better to higher temps than Kubota Super UDT.
And works great in cold weather just as Kubota Super UDT fluid.
No problems of any kind.

A proven product in my B7500.

Anyone that has a heat related problem with hydro fluid I would recommend trying Chevron Synthetic All Weather THF.

hwew…
First I would like to thank you for your efforts in ‘testing’ the effective use of Chevron THF. Not many would take the time to do this … even fewer would take the time to post the results.
There are always going to be people that think the manufacture will ALWAYS spec the best product for their application. (not always true).
There are others that get unreasonably defensive when they hear ‘synthetic’.
Then there are others that still think the s in SUDT stands for synthetic, just because the stuff is priced like a synthetic. (actually it is a multi-viscosity fluid, no synthetic).

I am slightly over due for a change of my fluids… I have been considering changing to a full synthetic… Using UDT or TSC premium fluid my trans temp has been in the 190 to 195 degree range. This is mowing with a 7 foot RFM with the air temp in the 90 to 100 degree range. (but with 40 degree air from my AC vents, love this L4200GST cab). I know changing to synthetic lube has dropped all my gear box temps, and I have always ran mobil1 Delvac1, (now available as mobil1 ‘Turbo Diesel truck’) in my diesel engines…
Looking at synthetics for the hydraulic system, you have pushed me in the Chevron direction, so I will check for the availability of 11 gallons or so in the Wichita vicinity… Thanks again, Kenny

fwiw:
i returned the tractor supply fluid and bought 10 gallons of kubota udt today.
got $73.73 for returning 10 gallons at tsc. paid $117.98 for 10 gallons at the kubota dealer. small price to keep from second guessing myself for the next 400 hours.

while at sam's club yesterday I checked out their tractor hydro fluid. it listed the mfg's is was compatable with. it also specificly stated it may not meet some mfg's specifications.

I don't know where you guys buy your Kubota fluid, but I need to find out!

I have an L4400 with about 90 hours on it. When I went to my dealer to buy the filters and hydraulic fluid for the 50 hour change, they quoted me about $42.00 for 2 1/2 gallons!! That's about $170 for fluid alone! I ended up using CO-OP 75 fluid, which says it meets or exceeds standards, for about $85 total!

The tractor seems fine, but I occasionally smell hot fluid when working the FEL hard in hot weather.

I am a synthetic fan, and have it in all the other fluids, but couldn't find the Chevron. But I will look harder next time.

Thanks for the info
Dave

The Amsoil tractor hydraulic/transmission fluid is supposed to be a top notch product. But, at $120.00 per five gallon bucket, it's a bit pricey.
