b2650 almost rolled need front wheel spacers

[CalG]

Not sure of your statement, put 3 inch spacers on rear of my GC 1715 and it made a world of difference in its stability.... As for slopes, you can go up a slope and you can go down a slope, NEVER across a slope....

How did you evaluate the pre-spacer instability in order to make the comparison?

 

[CalG]

Adding 3” rear wheel extensions and fluid ballast in rear tires of our B26 made a world of difference in stability and traction on our hillside farm.

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?

You can do some pretty simple math to see what extending the track width does side angles.

For example, if you had a 5' track width and your CoM was 2.5' up off the ground, you can draw a right triangle from the tire to the center of the track and then up to the CoM, and you'll find that's a 45° angle from the tire to the CoM.
To keep the numbers whole, let's say you extend the track by an entire foot so you've got a 6' track width. Now the triangle has a 3' base, and still has a 2.5' height, so that's now a 40° angle, so you'd be good for an extra 5° of hill.

Whether or not it's a great improvement is up to the reader; the numbers are going to be different for different tractors, and the effective angle of a hill will vary with every clod of dirt or grass or gopher hole that you drive over.

For all practical purposes, math is useless for any stability or traction comparison.

There are WAY TOO MANY VARIABLES!

The CG of all the tractors I have, is just about at floor level under the steering column.

After 7 pages, I'm glad both my rear wheels and front wheels are adjustable for track and the rears have cast centers so no ballast needed either.

me: Math shows the direct effect
Cal: "MATH HARD OWWWWWWWWWW MY HEAD"

Math clearly shows that widening the track, via spacers or flipping wheels or adding duals, will reduce the effect of the hill's grade.
What you do with that knowledge, like burying your head in the sand, is up to you.

Some good advice in this thread

You know the comments made were not based upon math. I have done the math, it doesn't provide one bit of reassurance that the tractor will not roll.

Oh, And I have spacers on the rear axle of the B2601. And the Hurlimann is a "low" tractor often termed as an orchard tractor, with many wheel settings that would suffice to keep the mathematical evaluators busy for days.

What does a 7% improvement feel like JUST as the tractor rolls over?

I like the way you chime in for the question posed to others.

Good going....

Please show me that sloping hillside without dip or rise, no grassy bunches , no rocks, and certainly no wet spots. And always carrying the bucket at exactly 3.5 inches above the soil surface. right?

I think I can answer this one. I feels like you had your chance. You ignored your margin of error and you F'ed up. Here's your sign.
