Loader lift capacity and ballast

[CobyRupert]

Have you tested your hydraulic pressure?
Kubota's have frequently been delivered with the hydro pressure set low. But usually it's only a few shims or twisting a screw to change it.

lots of links

^This. :thumbsup:

Find out what you're working with, then go from there. (Technique, ballast, etc...)

I keep reading about the stress and strain on front axles and FEL use...I would think front axles on non commercial tractors would be designed to support whatever the load capacity of an OEM FEL is...
Rear ballast is for stability

It's not about what the axle is designed for. Is more about longevity.

A tractor with no loader may last 6000 hrs without touching the front end.

A tractor with a loader that uses it to the MAX every day...might need attention after 800hrs.

And it could be anything in-between.

There is no denying that lessening the stresses on joints, bearings, seals, etc will make them last longer.

Pickup truck plows need front ends rebuilt much more frequently than non-plow trucks. All about longevity

This is why they make commercial/industrial machines...the typical CUT/SCUT is not meant for MAX use every day...!

Irrelivant how frequently or infrequently it is used. If you minimize the stress....things just don't wear out as quick. That along with stability is what proper counterweighting is all about.

It seemed relevant in your previous post...just sayin..

No. I was just illustrating two extremes.

On the light end is a tractor with no loader
On the heavy end is a loader used at max everyday.

Reality is somewhere in between for most of us. But we are all different in our uses and habits.

The point was, quite simply, the harder you work the front end, the more frequent you are going to be replacing parts.

So no, your comment, and parsing my out of context...not relavent

Do the base ballast on the tractor for what you do 90 percent of the time! Sometimes a less then full bucket is the best answer! Otherwisse remove the safety decals and live with what is left!

You don't have to have a plow truck to wear out pickup front ends. Heavy and frequent use of a winch will do the trick too. Just ask me how I know. Boy do I hate changing ball joints.

I've been moving rocks around (SWMBO is landscaping) and getting used to my new EA Wicked grapple. My dealer loaded all four tires for my hilly property, and my FEL is pretty small, but I can easily get the rears off the ground with a bucket full of gravel. The larger rocks in the grapple are even worse - curling the grapple changes the moment on the FEL, effectively increasing the load on the front. My 440 lb box blade was enough for the bucket, but the grapple with a large rock (pretty much at capacity for the FEL) requires the 800 lb flail mower. The extra weight makes a huge difference.

Almost an aside; Consider the load on your front tires and their rating, not just the axle.

For the arithmetic assume the weight of the bucket is out there at about its pivot, typically 4 ft or so and LEVERED on the front tires.
If you are into the "lift all you can and raise the rear tires off the ground" mind set you can assume that ALL the weight of the whole tractor, ballast and load is on those front tires.
Even if you are just a bit short of that think about carrying so much weight on the front TIRES and having one of them blow out.
Just ONE of them, say the one on the down slope.

Are you running at full throttle? Are the relief valves set correctly? :confused3:

I adjusted my new loader valve, it was bypassing at 1950 psi, now it's at 2250 psi, so more than 10% greater lift (2250 is what my dealer said it should be at.)

Considering it takes near 400 psi just to lift an empty bucket, you added another 20-25% to your lift capacity, not 10 %

PS
You can go another 5-10% on the pressure, (2,400 psi) just make sure you use a gauge and do not exceed the main pump relive pressure.
My loaders more than match the capacity of the tractors.
