b2650 almost rolled need front wheel spacers

Someone seems triggered

You may be advised, you address a person who has elements of their own design and making, on both Mars rovers and the Hubble Space Telescope.

I am not intimidated by the math you hold as shield.

But the math said it wouldn't tip!

After 30 yrs of operating all types of machinery I can't tell you how much slope is too much and I intend to keep it that way. This is one of those things that takes experience to know how much slope is too much. Unfortunately real experience comes from failure. So, error on the side of safety. Put the spacers on the rear, load the tires, and when you think you may be getting close to tipping stop and find another way to do it. Spacers 3" rear and 2 " front for me - I'm good.

Someone mentioned a front anti-sway bar. That would make a tractor more likely to tip over , not less, on a typical bumpy side slope.

So when it rolls less, It's more likely to roll over ! I'd be real careful on flat ground.

It doesn’t “roll less” or more. The rear axles are ridged to the entire tractor other than the front axle housing. If the tractor is rolling the slightest bit, you’ve already gone too far and have lifted the uphill rear tire off the ground.
Making the front housing unable to freely pivot, which helps keeps all 4 wheels on the ground, adding an anti-sway bar would only increase the likelihood of a ground depression, or hole, being hit by the front wheels, creating a quick rotational torque on the tractor

Bentrim > "Purchase and use a roll bar (ROPS) with a seat belt. If you do roll it will keep the tractor off you, and give you a chance to keep on mowing instead of helping grass to grow."

Many of the after market rollbars are no longer available. My understanding was that lawsuits largely shut that business down due to lack of testing and lost lawsuits. That and the dwindling number of pre-rollbar tractors still out there reducing the consumer base. I could be wrong on the reason.

I've never owned a tractor without ROPS. My first tractor was a MF 30B, then a TEREX 40B, followed by the MX5200. I buckle up on slopes. A friend of mine did not and got a broken back.
I admit I rarely buckle up in the Skid Steer but that would probably be a good idea even with the belly bar in place. I'm hesitant to push the gravitational limits of my machines. I usually find another way to do whatever it is. Call me a chicken but I will be at the dinner table after work.

Same question as post 61.

How are you making these evaluations and comparisons.

A "world of difference" suggests a very great improvement. Is that quantifiable?

I would say that I could physically feel the difference between my tractor having spacers and filled tires versus it not having them. Even on small slopes. My property has damn near 45° in some spots. You almost have to bear crawl up it for those not used to climbing the hills.

So for me it wasn’t chalk board and maths, it was my bubble level and the pucker factor feeling before and after which served as my gauge.

Regardless of the wheel spacing, the tractor "tilt" is exactly the same on any given slope.
Your "pucker factor" remains the same. There is NO part of YOU that can "sense" the center of gravity/ roll center of your tractor.

I wish you well with your feelings. Be careful!

Nope. That's not what tests show. More load transfer on the rear tires means increased lateral grip from tire deflection. So more roll acceleration moment.

Btw: wheel spacers greatly increase spindle length, which increases steering torque. With tractor power steering generally being weak, this means that counter steering attempts to stop the roll initiation are more likely to fail.
