re-positioning cast wheels farther out on rear Super M axles

To increase stability, I would like to re-position my rear cast wheels so they are 4 inches from the outer end of the rear axles on my Super M loader tractor. I"ve seen several M"s with the cast wheels close to the edge of the axle, but my Super M axles are obviously longer - by setting the cast wheels farther out, would I significantly risk damaging (bending) the axles if I am lifting/moving 1100 pound round bales with my 3 point? I don"t want to find out the hard way so I thought I"d ask.
 
I used to have the wheels set out on my 560 loader tractor and carried many bales with the fast hitch and never broke anything. Did it for years.
 
I don't have a manual for a SM but one manual I have shows how much weight can be carried safely with the wheels at different spacings.

well to mount a corn picker you have to slide the wheels way out and pickers aren't light. but to move heavy round bales I would not move the wheels out, with that heavy bale a foot off the ground you have a low enough center of gravity that its not goin anywhere. I would think you would be better off to add more wheel weights for stability than to move the wheels out on the axles.
 
I personally would not set them out as far as you are saying.

I live in a way "hilly" area that I mow,My rears "dished out" and measuring between the edge of the cap on the axle housing(thing with a grease zerk on it) to the edge of the cast wheel center, I run about 4" on both the right and left side maximum. I have never felt "un stable"while on hill sides. I can still get it on my "deck over" trailer with out any tire "over hang" off of the deck.
 
Yes, they slid the axles way out to attach mounted corn pickers... They also had a LOT of broken axles caused by mounted corn pickers.

If you set the width so the tires measure about 8' to 8'6" from outside to outside, you'll have plenty of stability for anywhere you should be going, and you won't compromise the axle strength.
 
you could add a set of clamp on duals too. that would give you a wider footprint in the back, add some weight and give you a little more stability. keep an eye out at any auctions in your area. a set of duals with fair tires can be had for anywhere from 50 to 150 dollars. i have 3 sets i bought at auctions, the cheapest set were peterson bolt on duals with pretty nice tires for 15 dollars. other sets were 25 and 55 dollars.
 
Errr, they don't just snap off. The process starts with rotating bending fatigue and the final fracture area is where most people look at it and say "it chrystalized and broke". The final fracture area finally became small enough that it could no longer carry the load and it "snapped" off.
 
Thanks everybody, pro and con.

I have decided to move the wheels 5 inches from the axle housing, which should give me a wider stance without compromising axle strength.
