I am assuming this is new problem. But did it happen all at once or slowly get worse?
The only simple thing I can think of is the fluid is low or you have a control that is not set right. Check to be sure nothing is bumping the lift lever or is not slipping down on it's own. Past those would think issue in the lift itself. ....

Well, some general troubleshooting.
If you pick up on the arms, do they push down?
If so then the depth control may be on.
did something bump the arms up then they crashed down hard?
The I would suspect the arm or rod that goes to the piston may have punched through or cracked the piston (happened on a ford 8n I fixed.) Would have to take it apart to see.
If you lift, does it lift smoothly? If jumpy, could be that your pick up line has a pin hole and is sucking air.
This shows up as if the hydraulic fluid has water in it, but if you put the same fluid in a sealed jar, will turn clear and the level will drop when the air gets out of the oil.
The release control valve may be stuck open or open too much. This is the valve that slows the drop of the arms.
