x500 or x534 your preferrence?

[IH3444]

Would someone please tell me which Tufftorq rear transmission these 500 series tractors have. Are they K72s? I can't find any info on the Deere site. Thanks!

Just found the answer, Congrats on the purchase! I forgot to mention it earlier, but the X500 has a very robust transmission (TuffTorq/Kanzaki K72)

I think the limit of the lift (approx. 4") is limited to how much of an angle the belt can take before being thrown off not the hydraulic stroke.

The soft cab was changed a year or so ago to a full 4 sided enclosure with a hinged door. The previous model was 3 sided (open in the back) and you had to climb in under the side flap if I remember correctly. The new cab still takes some time to install however I wouldn't be without it. Here is a video of my X530 with the blower and cab.

Well i'm glad they improved the enclosure, I just wish they would give me half what i wasted on my 3-sided POC toward what you have.

I would hold the comparison of the turning radius suspect. Just to satisfy my curiosity I see that the x749 I have shows a 21" radius while the x748 shows a 25" radius. Both with the 48" decks which are the smallest available on these mowers. When I bought the x749 I remember that equipped with the widest deck a 62" it was listed with a 6" uncut radius.

So I would expect the 4ws mower to have a smaller turning radius than the 2ws mower. Using a wider deck can reduce the uncut radius but has no bearing on the mowers turning radius.

Actually, I could see how a 4ws might Actually have a larger turning radius than a regular steer simply because of how that is measured. I would even venture a guess that while the 4ws might have a larger turning radius, it might actually have a tighter OUTSIDE turning radius than the 2ws. Again, it's all about the pivot point.

Would the number 1 and number 3 signify a non 4 wheel steer?

To me that is like saying my car is 6' wide on the inside but is only 5' wide on the outside.

Years ago most people who wrote manuals or specifications were trained technical writers. Today with the tremendous increase in the printed word there are lots of people copying and posting without checking for clarity or accuracy. Hence the term "read it on the internet".

1 is the turning radius of the shown 4ws tractor. I'm not really sure what they are trying to show with 3 but it does look like possibly the outside radius of a 2ws.

I understand the confusion here, but it isn't just the width of the car that comes into play when discussing this. When you add steering to the rear wheels, the length of the tractor becomes less of a factor. Ever watch one of those old ladder trucks with the guy steering the back go around a corner? That will help visualize what I'm trying to say in a very exaggerated way.

OK, the number 3 circle would signify a X500(2 wheel steer) turning radius?
The number 1 circle would also signify the uncut radius of said X500?

That makes sense.

OK, if that makes sense, go read post number 7 on down a few.

I would expect the solid lines to show the 4ws cutting radius and the dotted lines to represent the 2ws cutting radius.

Probably best to just ask a question or make a point as I'm not sure where you are going with this.

Pretty simple, the 4ws turns sharper than a 2ws. The 4ws has a smaller uncut radius than the 2ws. The 4ws turns inside a smaller outside turning circle than a 2ws.

The numbers were entered incorrectly in the specifications and some people take these things too literally.

 

[rjwerth]

Nobody is denying any of that. What that diagram does NOT show is the specified turning radius that you are having problems with. And that is because it would confuse people and ultimately is not as important as uncut radius. What they probably SHOULD spec is the outside turning radius that is depicted on the diagram.

See post 10 where it mentions the 2014 specs corrected.

About the fire truck, I wanted to drive one of those ladder trucks real bad when I was a kid.

Consider this, the wheel base is the same, the axle and tire width is the same and more importantly the decks of a given size extend out the same distance. Only way the 4ws can cut a tighter circle is if it turns tighter period.

Post 10 says the 534 has a larger turning radius than the 500. So I'm still confused here...

Nope. I'll give it one last shot using the most extreme example as I can: Take a 2x4 of any length you'd like. Lay it on a table twice as long as the board. Drive a screw as close to one corner of it as you can and spin the board. You will note that you have a turning radius of nearly 0 but an outside turning radius of nearly the length of the diagonal of the board. That represents 2ws. Now take that screw out and put it back in the table. Add another in the middle of the board but not all the way into the table. Take a string that is about 1/4 the length of the board (not crucial, but if it is too long, you will not get a good model) and attach it to the two screws. You now have a larger inside turning radius and a significantly smaller outside radius. This is what 4ws does. It changes the pivot point! Can't think of any other way to help you visualize it.

You may well be correct about the X534 I could not check the specifications on Deere's web site.

I was able to determine the x749 with 4ws has a 21" turning radius and the x748 with 2ws has a 25" turning radius.
I can tell you this much, my x749 turns a lot sharper between fences and trees than my L130 with 2ws, no doubt about that.

I understand what you are saying about the pivot point I get that. What is happening is that the 4ws with all wheels turning results in a tighter turning angle when eye balling the tires on my mower the wheel cut is about 75 to 80 degrees.
