Is there a way to engage the differential lock without keeping my foot on it? My leg is killing me from holding the lever down all day. Also the flange is loose holding the lever so it lays to one side ever so slightly. There isnt a way I can see to adjust it. If I disconnect the spring can I engage and disengage at will?
And is there a front axle lock?
Tks

I believe the differential lock is to be used occasionally, when needed for extra traction. I don't think it is intended to be locked all of the time. It is very difficult to get the tractor to turn, with the rear differential locked. I only engage mine when I need a little extra traction.

Like he said, you shouldn't need the diff lock engaged all the time, If your spinning one wheel that much you have a problem, either the lack of weight, wrong tires for the job, or to large of an implement demanding too much.

No you can not override it without doing damage to the tractor.
No smaller tractors do not have front diff locks.

The reason you're having pains keeping you foot on the peddle is because the use of the lock is a temporary function of using the tractor.

As mentioned, you can not steer your tractor if the peddle is in fact engaged. So if you have the differential locked and can steer your tractor you really do not have it engaged. You're just getting tired of holding the lever down with nothing locking in.

I neglected to mention I was plowing long straight rows of virgin ground. The tire on the new dirt never slipped but the one on the sod and mud kept slipping. When one tire slips the rest quit spinning. Makes no sense to me. So any time a tire slips, I either shift, hit the dif lock, or raise the implement till I gain momentum. Kinda isnt really 4x4...
Help me understand what Im doing wrong.
Tks guys

Do you have the rear tires loaded?
And you might need wheel weights too.

Plowing ground is one of the most taxing jobs a tractor can do.

Is it a single bottom plow?

There are threads about installing a lighter spring on the diff lock pedal. I never did the mod, but before trading the B8200 I did seriously wrench my lower back while using the diff lock. That was when I was young and indestructible!

The diff lock on my B9200 is a real pain (literally) to engage and hold in the engaged position. I suppose they use a stiff spring to discourage use or perhaps encourage only temporary use to get out of a tight spot.
The ergonomics of having to use your heel while bending the knee is ludicrous. Very much like trying to walk comfortably on thy heels. Thy Achilles doth protest vehemently. :)

Same thread sort of same question. How do I disengage front four wheel drive? The pto engage lever and seemingly the 4x4 lever move together. Ive tried everything I canbthink of.

It is hard to imagine that a differential on a Kubota would be anything less than indestructable but they need to be treated with respect or serious expensive damage can be done.

A while back there was a discussion regarding a Kubota with tracks seen at at dealer.



Tughill Tom posted the following regarding the use of tracks:

It's been tried here, it didn't turn out well for Kubota's, they were breaking the Rear Diffs out of them, just a bit to light for duty they were being used for. Most clubs this way went up to either DJ or Case with tracks and over a 140HP. I'm hoping to go back to OLD School and go with a Pistenbully for our next Groomer. Currently running 2 over 28 years old on 30 miles of trails and still getting it done.

There are big tractors with tracks. Designed from the beginning with tracks and steered like a bulldozer by slowing one track or speeding up the other.
The differential is designed for the expected loads.
