That comparison with rim guard in the rear tires and no 3 point ballast confirms what the other video claims. Loaded tires, while making the rear heavier and more stable, does not remove weight off the front axle.
Yup!
And so many people claim it's all they need to have for loader work, or maybe a lightweight 250 Lb rear blade!
Another false gauge that some use is "the back tires didn't come off the ground" yeah, but if 95% of the total tractor and load is on the front axle, a axle rebuild is right around the corner, besides the tractor can tip over MUCH easier with that mismatched "balance"!
I say that if the tractor comes with a backhoe, or is an option, that's a good starting point for how much weight is needed on the back for front loader work ... While it's possible to add more weight with a BH on, it's not easy, so ... I figure the manufacturer decided that a TLB package is not going to overload the rear axle, but also takes enough load OFF the front axle ... !
