My compact 4wd tractor loader has weak lifting power. I've owned other tractors, and they lifted much more. The bucket can tilt and lift double what the arms will lift. I've opened the knob that slows the flow to the loader. Any ideas? I have several items needing moving that it won't lift.

Which John Deere model is this and which "knob" did you open?

Yeah, model number would help us but the JD compacts are not known for having good loader lift capacity. Almost all other compacts will have hundreds more pounds of lift.

Have not noticed lack of lifting power with my JD 4300. Have significant ballast and rear wheel fluid, and still can lift enough with the loader to bring the rear wheels off the ground.
Had a couple occasions to operate similar size hp New Holland and Kubota loader tractors without near the lift power in the loader as my 4300. Don't remember the model numbers, and it isn't important. But left me quite pleased with my JD 4300. No good comes from bad mouthing other brands.

Not bad mouthing, that's why I asked a model number. The 1 and 2 series sub compact and compact tractors are known for poor lift capacity compared to simular sized machines from other brands.

I've got a 1025R and am easily able to lift the back wheels off the ground with the loader if I don't have enough weight on my 3 point.

The tractor he lists is the Iseki TL2300, no mention of JD.
OP - get the hydraulics tested, you might be able to add a shim or so for more power.

It’s in the John Deere sub section

I looked at the specs of your tractor and the loader is rated at 700 pounds at the pins. Of course you don’t lift things at the pins so a load in the bucket is less. Forks will make it even less. I own a newer JD 2025r and put a pressure gauge on it, it was on the low end of spec so I turned it up. I’m not sure if you can do that with yours or not.
Buy a bigger tractor if you need to lift more
This is an operator issue with unrealistic expectations for a SCUT
I shimmed the pressure relief valve under the seat on my 790 Compact Tractor 15 or more years ago and am very happy with the additional lift capacity. It's not IMO unsafe or beyond the capacity of rams, pins, or the frame. Here's a post I found with the link to the thread: "
Had very good luck installing the shim kit on my 790. It's part number AM875169. Others have tested it and it increases the pressure to 2500 psi.
I don't know the exact lift capacity, but I have a disk that weighs just under 1200 pounds and it handles it well now. It would not lift it before. That makes the tractor plenty light on the front end, even with the loader attached. I have had no problems so far, nor has anyone else I've heard of.
To install the shims slide the seat forward and open the cap on the far right. It's the taller cap and is under spring tension. Pay attention to how you put them in, if I remember correctly, they go right underneath the cap. What you're doing is setting the spring tighter on the relief valve so that the pressure is allowed to build higher before the oil by passes."

790 Lift Capacity / Shims to increase hydraulics
I haven't found the procedure listed for this. Supposedly you can buy shims from the dealer and increase lift capacity of 3pt hitch from 815 lbs up to over 1200; can someone whos done this describe where the shims go and how to do it? Why didn't John Deere sell it with more capacity?

I mean, 700lbs at the pins is probably 500lbs realistically? Can it lift that?
A CUT will lift 2500-3000 at the pins. A very big difference

Yes, shimming the relief valve will increase lifting power at *all* hydraulic implement attachment points. I did the same on my baby x595 because the loader was not much help at all. I think it could get 300ish pounds up originally. It was running 800 psi as I received it. I shimmed the implement relief valve to get about 2,000 psi and it's *much* better now. Just be *absolutely sure* to use proper ballast - it's *very* important on smaller machines - and keep any heavy load as low as possible to the ground.

Older thread.
Did the OP ever get it figured out? Test hydraulics?
Bad advice to say that a loader leaking down is seals and bypassing internally. (for anyone else in the future that reads this) So I wanted to make that correction
