Ballast AG tires ballast

[BobG_in_VA]

Beet juice is non-corrosive and heavier than water...hence the 50%...Windshield washer/water may be corrosive so you need to cover the rim...which is approx. 75%...ie. to the top of the rim itself...I do the windshield washer stuff....as I'm not gonna fool with oozzing/stickiness of the beet juice if I have a flat...Shrps74

Power hop is corrected by adjusting inflation pressure and axle weight (ballasting) to the needs of specific applications. Blanket statements concerning tire fill levels having a linear effect on power hop are incorrect.

Correct. Some ballasting to alleviate requires less than 40% fill and further differentiates whether the tractor is mfwd or 4wd.
All and all, not applicable to the way I use my tractor as probably for a lot of others here.. They should have filled them to 75% as their blanket "theory" doesn't effect my skidding logs out as much as weight.

I didn't "power hop" once while pulling this stem out nor with the other 100 stems.. Must have been the 50% tire fill

Wonder why they are saying only 50%?

That's what I'm wondering. Our son has 2 tractors over 100hp and both have loaded rears to the top of the rim or about 75%. It's never caused a problem. One runs 18.4 x 38's and the other is running 16.9 x 38's. His L3940 with R4's is also filled to the top of the rim. His JD 5065M has enough weight in the rear that it's never needed filled tires or weights.

Just a guess but it may have more to do with the harmonic syncopation of 4wd tractors moving at speed tilling certain soils. I think Rick B is correct is that tire filling companies grabbed onto the "latest findings" and using that as a blanket excuse to use less fill for the same money. I've read that some larger 4wd tractors are recommended to fill tires at only 38% full.

This is like saying that everyone should be doing the same thing even if it has "zero" pertinence to others because it's advantageous to whomever has a stake in the matter..such as mandated ethanol use for inner city pollution but mandating it also for places like Vermont or Idaho.
