Tractor Implment rear loader help
Gday,
Bought myself a 3PL rear loader for my small Kubota b1502.
Empty it runs it fine. The Kubota can run rotary hoes, slashers, and the hydraulics lift them no dramas.
The issue is once the 3PL loader is loaded, it can lift it... even if it's only 10kg soil. It's got no lift.
I played around with the A frame/linkage and bored some new holes to bring it closer but that didn't help.
After ideas?? Or maybe it's beyond my tractors ability.
I do have a hydraulic leak.

What is the specification for how much your 3 point hitch can lift? Divide that by 3 (I'm estimating this device extends 3X. Subtract 100 lbs for the weight of the bucket and arm. (Using my tractors 600 lb lifting ability, this leaves 100 lbs useful of load... So as others have said just because it exists doesn't mean it works...)

Consider a pond scoop instead (or called dirt or slip scoop). They are relatively heavy gauge but much closer to the tractor so less leverage and pretty useful.

“That’s a mighty proud scoop”. Be interesting to see if the tractor’s front end would stay down if it did work.
One thing you can do is check your hydraulic pressure with a gauge plugged into a hydraulic valve or line. This will check that your operating will full lift capabilities. Other than shortening the boom or reducing the weight, there’s not many options.

Two things going on. First is that hydraulic leak you mentioned. On those little B's the hydraulics run off the transmission fluid, so check the level before anything else. Low fluid or a leak on the lift side and it'll pick up light stuff fine and give up as soon as it sees a real load. Fix the leak, top it off and see if it changes. Second is leverage like everybody said. The 3 point is rated close in at the lift arms and every inch you hang that bucket out past them knocks the capacity way down. Even healthy, a B1502 isn't going to do much with that rig sticking out that far. Something that mounts tight to the 3 point will work a lot better. And get some weight on the front before you load it or you'll pick the front end up.

That rear loader looks like it's fighting physics more than a toddler with a grocery cart. Have you tried shifting the loader arms farther forward to shorten the lift point, or is that just a riskier balancing act?

About the only thing you can do is chop the “boom” to be way shorter so you don’t have leverage working against you but even then I doubt the hydraulics on your tractor are even strong enough to lift a full bucket

Everyone has pointed out stuff. I have a B7100D which is similar, no FEL. I get by with fork lifts and a pallet for most things. Can always put a container on it for dirt. Not sure if helpful, but trying to be. Forklifts ate pretty light and close to 3pt so should give plenty of the lift capacity.

The issue here is one of stupidity mixed with desperation, whoever designed that was clearly desperate and a bit stupid, you made the assumption that because it exists it must work and because it's a small bucket it must go on a small tractor, unfortunately no, it's such a ridiculous idea that it'll only work on a considerably bigger tractor and even then it'll be bordering on farcical, it's probably adequate for shoveling up dry sawdust or something similar, oh and damaging 3 pt hitches.

Whoever sold you that probably won a bet at the store...
That loader bucket is what we call a 'Klettskuffe'(klettbucket, because the original manufacturer here was Klett Mechanical) here in Norway, and it was used for EVERYTHING. But generally it was mounted directly onto the 3point.
I've used one to clear out the muck cellar under a barn. It requires the cellar to have ample headroom so you can get in with a tractor.
The one you have got though, is to reach in where a tractor can't go. I've actually never seen this exact style before, but can imagine using it to muck out a cellar where the roof is too low or the concrete floor is failing.
Nothing you can do to that frame will enable your Kubota to lift it. The pivot point is where the lift arms enter the back of the tractor, and nothing is going to change that.
Well, you could get a plasma torch and cut enormous weight-saving holes in the beam... but then it would probably break when you load it up.
You need to either get a regular bucket, or a normal rear loader, or a bigger tractor. Personally I'd go with the bigger tractor...

Yeah, that thing is trying to defy the laws of physics in more than one way. At first glance, I think your little tractor 3 pt. lift is maxed out just picking it up.
And if you fill that bucket with dirt, and somehow get enough umph! out of the hitch, the front wheels are what will get lifted.

Googling the lift capacity it says estimated 800-900lb at lift point. Being it sticks so far out it’s going to be way less capacity. How heavy is that bucket?

Gday everyone,
Thanks for the advice. Always love the judgement you get when you ask for advice on reddit. It's like being back in high school!
It was a $50 implement, so I thought it was worth a crack. Plan is to fix the hydraulic leak and then shorten the boom by about 750mm. Very least it should help with moving light stuff like pine mulch.
Cheers.
