Tires Moved tires in rear to wide position.

My Kubota manual states to not reverse front wheels, but I don't know about JD. My Son reversed his front wheels on his 4300 with R1s. It "plows" real bad when turning.

I also agree with previous post, you gain little stability when reversing fronts. By the time the front axle is what's holding you upright, it will be too late for reversed wheels to offer much hope.

On my Kubota I moved the rears out until the inside of my front tires and rear tires are an equal distance apart. This turned out to be the second from widest position. Changed the stability of the tractor considerably.

You may already be here, but the best thing you can do is weight the rears with fluid or bolt-on weights to gain stability.

I moved my rear tires into the wider position. I didn't just swap sides because that was too wide. I removed the centers and reattached them in the middle postion.. I have not used it yet but it definetly moved them out and made a wider stance. I am not sure I am going to like it that wide. Do any of you guys use yours in a wider position and also do they make wheel spacer where you can leave them on the narrow position and just space them out a few inches? Thanks

What size tractor did you do this on?

Do you have any pics before and after?

I like this idea. I'll have to see how mine measures out. I may do the same if it is not already that way.

Changing the fronts also gains almost nothing in stability as the front axle pivots in the center.
.

From my personal experience I found that moving the front tires to the wide position did improve the stability when carrying a loaded bucket. The front axle may pivot in the center but the travel is limited by the bump stops.

Sorry I didn't put it in the post, the tractor is a jd 4520 with backhoe. I used it today to pull out my dump trailer when I got it stuck with a load of wood. The wider position really improved stability but the tires rub the inside of my fenders on my gooseneck trailer when I load it.

So you are tipping the tractor up onto the axle stops? As OVRSZD says,
it may be too late to avoid a rollover by then. On my tractors, one rear
wheel is quite a bit off the ground when the front axle tips enough to hit
the stops....not a fun place to be with a full load in the bkt!

I've never seen this in any John Deere manual. Can you provide a link?

I stand corrected. My 4300 OM says you can reverse the front wheels
(see page 75). My other two tractors and my previous Kubotas and JDs
said don't do it without saying why. The OM also talks about having
wheels with some tire options that allow you to put your wheel mounting
flange on either side of the hub, doubling the combos to 8 widths. I have
never seen CUT wheels that could do that. My 4300 R4s allow 2 widths,
and my Bobcat R1s allow four.

Yeah, Richard, that's the scrub radius "talking to you". If you project an
imaginary line thru the kingpin (the steering pivot axis) toward the ground,
it should intersect the ground approximate in the middle of the tire tread.

I experimented with my old JD955 reversing the fronts (with new AG tires)
and it really ripped up the ground, even in 2WD. That tractor had pretty
small front axles and a strong loader, so I see why JD wants you to keep
the wheels at the narrow setting. The 4300 is a much bigger tractor with
much bigger axles.

Apparently, on my JD 3520 with Ag tires there are two positions for front wheels and eight positions for rear wheels. This is what the manual says :


Changing Wheel Spacing and Tread Width

The front and rear wheels can be mounted in wide or narrow positions to increase or decrease wheel spacing. To provide best stability, operate machine with rear wheels mounted in the wide tread position whenever possible.


Front Wheel Positions:
Wide position - Install wheel with valve stem to the inside.

Narrow position - Install wheel with valve stem to the outside.

Rear Wheel Positions:

For 8 position wheels, the mounting flanges on the rear rims are closer to one edge of the rim than the other, allowing the inner wheels to be mounted in different positions. By changing this position of the wheel on the rim, up to eight different tread widths can be achieved.

Do the king pins really have that much angle to them? I never noticed that.
