Brake steering?

[RobertN]

The Turning brake function on my Kubota is useless, and yes sometimes it would be handy.

I think the turning brakes are really a left over. They just did not design two brake systems, one for gear and one for HST. I think it's the $$$ of stocking and building two systems.

The other factor I think, is that with power steering and all, they probably don't think we need turning brakes. You figure the old tractors with no power steering and heavy implements were hard to steer, so turning brakes were a great thing.

Another factor is probably that you don't want turning brakes with a 4x4 anyways; it'll tear up the drivetrain. If you hit just one brake, it'll stress the whole drivetrain.

Kevin,
I decided on a JD 4700.[[[ what JD did you purchase? Can't find a profile for you! ]]]

Will have profile, etc. soon, w/pix & info about my tractor which is a little bit "different". may get it this weekend or next, ...watch for "Superbaby" post /w3tcompact/icons/laugh.gif

RobertN,

I haven't seen any mention of this: [[[Another factor is probably that you don't want turning brakes with a 4x4 anyways; it'll tear up the drivetrain. ]]]

How bout it guys, ...any "torn-up" 4X4 drivetrains out there? Would the mfgrs. not warn of such damage, if use actually means "mis-use"? Seems like they'd be asking for trouble w/customers with such "problems". /w3tcompact/icons/crazy.gif

I used my brake steering quite extensively when discing last fall as I was going up and down in rows. I did use the 4wd, but honestly cannot now remember if I disengaged it or not. I remember being very busy at the end of each row between lifting the disc, releasing the diff lock, throttling back a bit (I was discing pretty fast) and executing the turn with the steering and brake. It is very possible that one of my other tasks was to disengage the 4wd and it certainly turns tighter in 2wd anyway. In any event, the brake steering made all the difference for me in saving time not having to back up and realign with the row. It is pretty hard on the ground though, and I wouldn't consider it for finish or even semi-finish turf (though I've got R1s). Hope this helps /w3tcompact/icons/smile.gif

I wouldn't think hitting the brakes would do any more damage then having one wheel in a slipping condition and one wheel not, which can be very often. Granted it doesn't work very well in 4WD to use the turning brakes, but most of the time I'm using them when the front wheels are off the ground or just about off the ground.

<font color=blue>. Such an obvious screw-up made me wonder what ELSE (maybe-not-so-apparent) was designed using the same "thinking". </font color=blue>

Why the inflamatory statements? This board does a great job of answering questions in an honest, unbiased fashion... the implications of shooting off at the mouth really hurt what the board is all about.

<font color=blue>concerning this "turning-brake" issue, I'm still waiting for ANYONE to make "good sense" of it!? </font color=blue>

If you refer to the American Society of Agricultural Engineers, part of the definition of a farm tractor is that the clutch is located on the left while two brakes are located on the right. Kubota wants to keep the classification of farm tractor so until the ASAE changes its standards, the brakes will be on the right.

<font color=blue>like the poorly designed "old-style"front axles on the JD 4000 series, that have been changed.</font color=blue>

There is a big difference between a tractor that is designed incorrectly and needs major modifications and those that have been designed to meet standards. I don't even see how the two compare.

<font color=blue>I suspect that the reason the engineers (or the bean counters) designed them that way is to save money,</font color=blue>

It costs no more money, no engineering feat, no extra parts to put the brake on the left. Just a shaft under the transmission. Kubota did have the brakes on the left of their front mowers, but by no stretch of the imagination would that of been considered a farm tractor.

Turning brakes were designed to make a tight turn at the end of the field with a two wheel drive tractor pulling implements. If you have the tractor in 4WD with a front loader, you will only be dragging the rear tires around. The front axle will turn at its intended speed and make little difference in the turning radius. You are much better using the forward and reverse of the hydrostat to put you in position.

A little off the topic, those of you that saw the JD comparison video, please note that Kubota was not even mentioned (due to the fact it has a tighter turning radius then the JD's comparable tractors) and with the NH SuperSteer, they had the bucket down... even if just in the float position (who knows if there was down pressure applied)... you are negating the intention of SS by lifting pressure off the front wheels.

I get excited when anyone purchases a compact tractor... no matter the color. Everyone finds their own perfect fit. Remember..."we're all in this together". I'm impressed how level headed everyone remains although I am sure there is much bias out there (I'm probably at the top of the list). Keep on tractoring...

Hi Snell,

Wasn't trying to be inflammatory, ...should have said "WHAT SEEMED TO ME an obvious screw-up (after getting no reasonable explanation from anyone), made me wonder ...etc," .

With this "correction"I'm simply making a statement of fact; it DID "make me wonder, etc." If my "uncorrected" statement constituted "shooting-off-at-the-mouth", ...I apologise! /w3tcompact/icons/blush.gif

Remember, your "explanation", if indeed you can speak for Kubota, is the FIRST one other than "you don't need it anyway!", that I have heard from anyone, over the last year spent talking to Kubota dealers and seeing the question discussed (not just this-time) on TBN. Seems the dealers would know/say what you have said, if that is in fact "the answer".

As to the ASAE definition issue making "good" sense, I'll leave that to someone else to decide. (One of my hobbies is small-boat-design, and many a design has been "warped" away from "performance" goals, to make it "fit" some class restrictions, Such artificial design-considerations have always seemed inappropriate, TO ME, when the fundamental "honesty" of the sea's requirements are considered. The "open-class" design world is the one where people can do their best to meet the requirements of moving a form safely-and-efficiently through the various states of the waters surface, rather than their best to meet some other PERSON'S "definition" or standard. That is the way I want MY boat designed. That is the way I want MY tractor designed.

In other words; design it to DO-THE-JOB, not to fit some "definition". /w3tcompact/icons/frown.gif

I am a little surprised that my (repeated) observation that Kubota "makes great tractors (as evidenced by the many happy owners reporting on TBN,)" apparently did little to keep you from being "inflamed" by my other statements.

[[[There is a big difference between a tractor that is designed incorrectly and needs major modifications and those that have been designed to meet standards. I don't even see how the two compare.]]]
If both "paths" lead to a tractor that doesn't do-the-job in the best way, it seems TO ME that THAT is "how the two compare".

[The "bean-counter" quote was not from my post, so I won't comment on that.]

[[[Turning brakes were designed to make a tight turn at the end of the field with a two wheel drive tractor pulling implements.

Okay. So if I want to make tight turns, pulling implements, with my (now-in-2WD-so-I-can-MAKE-tight-turns)tractor, I will use my turning brakes (right?). Now, as I was saying, ...about that pedal placement...!!! /w3tcompact/icons/wink.gif

I hope that honest opinion, even strongly-differing or plainly-stated, IS what the board is all about.

Respectfully, /w3tcompact/icons/smile.gif

Snell,

...sorry, I meant to include;

Regarding "bias" effects; I was "shopping", trying to decide the wisest-use of limited funds, having NO tractor experience or "brand-loyalty", and actually having been influenced somewhat TOWARDS KUBOTA by the enthusiastic owners on TBN, ...when I formed the impressions I have referred to here in this thread. The closest dealer to me is a Kubota dealer. So I don't think bias was a factor (at least not consciously,) in my thinking.

My TC33D is a 2000 model.I kinda agree that brakes are on the right both because of cost and on the non-hydrostat model it would be the most logical place to have them. Of course for the extra money that the D model cost, and they had to add go pedal any way, they could have put the brakes on the left side. But then, maybe none of them use the FEL for back dragging dirt/w3tcompact/icons/wink.gif

With all due respect, I'm not sure the discription given, of what makes a farm tractor (required clutch posistion?), is valid. New Holland TC35D, TC40D, and TC45D certainly meet "farm tractor" status here in KY. OK, small farm tractor... All have standard, very useable turning/steering brake pedals on the LEFT and two seperate Hydrostat pedals on the right (forward & reverse). This arrangement is one of the several deciding factors in my purchase of a NH TC35D. Also, I don't believe many consider the hydrostat to be, or have a clutch. IMHO the issue is manufacturing $, additional parts/part #/stocking inventory... , to modify tractor models that are seldom used in the type of situations requiring brake steering. Remember, keep your ROPS up and at least two of those tires on the ground.
