Hydraulics question

[koolNAA]

Ever since i got my NAA back. when i go to use the loader, it acts funny. I can raise it fine, but when i go to lower it there is no resistance to the loader it seems. Whatever i have in my bucket as i lower the bucket it will just slam it to the ground there is no control. Like it doesn't have a controlled release pressure. Is this the way my loader was designed? Its a freeman loader. the cylinders are leaking a little bit but I didn't think that would cause the issue but i could be wrong. I know there are some draft settings and some other things i haven't tried to mess with. I just don't wanna go turning screws or adjusting things i shouldn't..Any help would be appreciated to lead me in the right direction. I was trying to go through the manual i just not sure what it may be

don't know what those tractor/loader are supposed to have, but I have a Farmall which has a one-way restrictor, that allows full flow in lift, but has a small orifice in the drop direction (think leaky check valve).

Does it have its own external pump & control valve or does it run off the tractor hydraulics and control valve?

TOH

It runs off the tractors hydraulic system. It has hoses that run to the back of the tractor that "T" into the factory setup

Do you have a control valve under the seat something like this , with your loader lift cylinders teed into one of the valve output hoses?
