Tires filled with Beet Juice too heavy for landscaping and field work?

They increase the stability of the tractor but they do not transfer the weight off of the front axle.

I've heard of this mentioned before, but for the life of me I can't see how adding weight to the three point transfers weight off of the front when the bucket is fully loaded. It seems that it would keep the back axle on the ground and allow the bucket and front axle to carry more weight without getting tippy on the front axle pivot. Weight on the 3 point is so close to the other fulcrum point (the center of the back axle) that any weight transferred back from the loader would be marginal.

We have a 5610 Ford 4x4 that weighs 13,600 pounds. It is heavy enough to do something. All four tires filled. Belly Pan, cage, loader, grapple, all add weight.

It has to be a significant amount of weight to do any good.

Wheel weighs, fluid, and an implement on the 3ph all increase what the loader can lift.....and all also increase the load that is gonna be placed on the front axle. Up to the point in which significant weight on the 3ph is added to transfer enough weight.

On an average 40hp sized tractor....no weighs or fluid and a light 350# rear blade is gonna put less weight on the front axle when doing loader work than the same tractor with filled tires and an 800# blade

Wheel weights or fluid in the tires will not transfer weight from the front axle, BUT they will aid in not letting the rear wheels lift when using the FEL.
Weight on the three-point does aid in transferring weight from the front axle, think of the rear axle acting as a fulcrum of a lever consisting of the space between the front axle and the load on the 3-point.

I totally understand the concept of counterweight for lifting a load, it's the claim that counterweight on a tractor 3 point takes stress off the front axle I can't understand.

Well I just did an experiment with dad's 630 Deere to see if it would lift a full icb tote.

With the tote empty....the tractor weighs about 6000# with the forks, empty tote, and wheel weights and I'd guess at least 2000# over the front. Certainly enough weight that I couldn't lift it with my bare hands.

Put 260 gallons in the tote...tractor lifts it....but barley.

I can walk to the front of the tractor and pick the front end up with my bare hands.

What part of the concept still eludes you? Weight BEHIND the rear axle will take weight OFF the front axle. Simple leverage.

How much is a simple calculation. Distance behind rear axle the weight it....how far forward the front axle is, and how much weight.

1000# at 3' behind the rear axle will remove 509# off the front axle if the wheelbase is 6'.

Same simple concept with a loader. Lifting weight forward of the front axle takes weight off the rear axle

Did you ever play on a teeter-totter? You push down on one end and the other end goes up. If the rear axle is the fulcrum, the rear weight is pushing down and thus makes the front end lighter.

For an easy demo lay 2 pencils on a table. They represent the axles. Now lay a ruler across both of the pencils. One pencil at 4 and the other at 8. 1 is the rear ballast and 12 is the bucket. Press down on #1 and #12 goes up. This will shift some, not all of the weight to the rear axle at #4. If you press down on #4, the rear axle, the front axle acts as the fulcrum and must carry the bucket weight.

Works until the load on the loader exceeds the ballast and the the tractor is balanced on the front axle at which point 100% of the weight, tractor, load and ballast is on the front axle. A tractor without ballast won't pick up much at all, front axle never carries more than the weight of the tractor and load. Add ballast and the front axle is carrying the full load on the loader, plus much of the weight of the tractor and ballast. (Ever spin a back wheel with a full load on the loader?) The front axle becomes the primary fulcrum and the load on the loader is further from the fulcrum than the ballast is from the rear axle. If ballast didn't increase the ability of the tractor to lift, then I could accept the concept.

The 3 point ballast does nothing to the capacity. The rear ballast just makes the tractor safer when using the FEL. If you are picking up the rear tires with a ballast on the 3 point then your ballast is not heavy enough. The rear ballast is to keep the rear axle on the ground so it is the fulcrum, and the front axle does not act as the fulcrum.

Remember on most tractors the front axle can tip from side to side. The rear axle does not tip side to side so you need the load on the rear axle for stability.
