The hydraulic system on the numbered Cubs is one way. Meaning hydraulic pressure to extend the cylinder(s), implement weight to retract the piston.
If the cylinder(s) are already extended to the max, engine will bog down, and no movement of the cylinder. You will need some type of weight/force to retract the cylinder.
The hydraulic control lever will return to the center/off position when released - if that was your question.
Edit. Check the hydraulic fluid level. If you had/have a hydraulic fluid leak, it will drip all over the shop floor.
2nd edit. Check the hydraulic fluid level with the cylinder(s) retracted.
