what oil to use?

[jerrell]

I got the B6200E with a tiller about a month ago and i used it to till up about 1/3 acre, ran like a champ no noises and did an excellent job, i got me a manual and changed oil, hydraulic fluid, and changed oil in tiller. i have two questions, what oil do you use for the hydraulic oil and what oil for the tiller. i ussed 80/90 oil in tiller, and used TSC premium hydraulic oil for tractor, while tilling today the gears was more noise than it did the first time i tilled, and the oil i drained from tiller was so thick it took 30 min to drain and i had it upside down to completely drain, . I'm just wondering if the oil i used in the hydro and the oil in tiller was thick enough, both looked sorta thin for the job they do.

If its a hydrostatic transmission, use Kubota UDT or equivalent in the trans. If its gear driven, use 80w90 gear oil unless it has external hydraulics added to it, then use the UDT. Use 80w90 in the tiller.

Even with no external hydraulics (like FEL, backhoe, rear controls), there is still the 3 point, which uses the trans as a holding tank for the fluid. So shouldn't it always be hydraulic fluid in the trans? And my impression (from reading, not experience) is UDT for HST, and any good brand hydraulic for gear drive.

My L275FL 4x4 standard trans, (8 forward & 8 rev), calls for UDT. My HST's call for UDT. That keeps it simple for me, just keep UDT on hand for all my tranys.

I do not know if UDT is called for in all standards but I believe it is.

If in doubt call your local Kubota dealer.

I use 85W-140W in all my implement gear boxes and have never had a problem. I also use it in the front axle of the L275.

Hope this helps.

I know how everybody gets sensitive when it comes to oils on this site but I'm only going by what Service Dept Vic says in one of his videos about Trans oil changes that is posted on here. Basically he states that if you don't have a FEL, then you don't need to use UDT in a standard trans, but its not going to hurt if you do, its just unnecessary. Also, you wouldn't want to put a straight hydraulic oil in the trans, you would have to use either gear oil or a combination (TDH trans, diff, hydraulic) fluid such as UDT. I'll try to post a link to the video.

Wow. I'm not one of the hyper sensitive guys, but I never would have thought 80W90 in the trans given that it feeds the hydraulic pump for the 3 point lift. I know there is not that much difference, but just as he says in the video, there are differences, so I just went along with the "always use a rated hydraulic oil" school of thought. Doesn't matter for me personally because the number one reason I bought a tractor was the loader, so I need normal hydro fluid anyway.

Also, much thanks for the video. I had been pondering whether that inexpensive hydro flui from Wally's would be ok for my aging (and growing apparently ) fleet. Looks like according to him it is, and that's good enough for me, so that will save a few dollars.

Just remember cheap oil is cheap for a reason, low quality. Not saying it won't work but don't expect in to perform like a high quality lubricant does.

I always used 80/90 gear oil in the trans of geared tractors with no FEL. My newer rigs w/FEL get Kubota UDT2.

In some cases, I completely agree. But in these days of MBA "branding" and such, it's not uncommon for the generic (whatever) to be from the same batch as a high priced "branded" product with no difference but the label. The problem is, identifying them to start with, and it may change when names (brands) get bought, or when another bidder undercuts. I just can't see paying to the high priced Kubota fluid in my beat old gear drive (I would for HST), particularly when there is no hard evidence supporting the value. I would also pony up if it were something I based my livelihood on, or even something I planned on spending a lot of time working. But that doesn't apply to my use on my little property I've been wrong before, and I'll be wrong again, and I've changed my mind over time on many things, but I doubt I'll ever see any evidence on my tractor that proves one way or the other on this topic.

Your tiller may have had 0,00,000 "pourable grease" I dont know what brand of tiller you have but King Kutter does not use 80-90.

The universal oil is known as HT its meant for trans and hydos ,Regular hydo fluid is strictly for hydos and not tractors that have one reservoir for everything.

 

[jerrell]

I just hope i didn't mess up, I used TSC's top quality 80/90 in the tiller, it doesn't have a sight hole nor dip stick (has chain drive on R side, Mashio brand) so i filled it up to about an inch from the top, about 2 gallons,

i used TSC top quality hydraulic oil for the tractor's transmission and 3 pt lift, took 14 quarts, on the 5 gal bucket it stated for Kaubota and many others. i have a Belarus that uses 30 w oil for tranlny and 3 lift.

It just seemed the oil for the tranny for the Kaubota was a little thin to me. i used premium diesel oil for the engine . i just hope the oil for the tranny is thick enough, it makes a squeal when i lift the tiller, would it be wise to put a little 30 w in the tranny to thicken it up, or do i need to change to all heavy weight for the tranny, i sure don't want to mess up the gears. the little tractor and tiller is a real workhorse.

 

[Bluegill]

You are probably fine, but I would have gone to Kubota for the trans oil.
Any good diesel engine oil will be fine.

I have no idea about the tiller. My first thought would be 80/90?

You keep saying you used TSCs hydraulic oil in the trans. If its a straight hydraulic fluid, drain it out and replace it with either a universal TDH (trans, diff, hydraulics) fluid or 80w90 gear oil. You don't want to use straight hydraulic oil in the trans.

Yes to that!

 

[BadDog]

Sorry, I'm new to this. Earlier when I said hydraulic, I meant the TDH as recommended in the video.

I would ask your kubota dealer when in doubt, I recently changed all fluids on my L3800DT (gear drive w/FEL) and the dealer recommended kubota UDT for the trans/hydraulics. They said if it was hydrostat then run the UDT super. I would think the 80/90 for the tiller would be fine. Is there a manual for the tiller?

I run Super UDT 2 in mine and I have gear drive. That is some very good oil!

 

[jerrell]

OK , called Kubota dealer, and was told the oil i used , Premium Hydraulic lil from TSC would work, explained the situation to him and he insured me the oil was safe and since i live so far from a dealer , gonna try it , works good so far, used the tiller again yesterday to run over the garden area and everything working OK/ thanks for all the info, if i ever get close to a Kubota dealer will pick up some from them for next change out.

 

[Kubota Newbie]

Your Kubota could be as early as a 1983 model. At that time they were using SAE 80 gear oil for the shared gear drive/hydraulic systems (from my M4500 operators manual circa 1985). Later rec is for a multipurpose hy-tran fluid like UDT.
There will be more gear noise with the thinner oil no matter how much you pay for it or who makes it.
Down side of a gear oil in a hyd unit??? It foams and traps air bubbles with extended use making the hydraulics seem spongy and slow.
Down side of using UDT or a compatible (of any brand) in an older gear drive tranny??? More noise (but it won't hurt anything).
