Just bought this. Found it about 10 minutes from home. Lady asked us to plow her a garden spot and this was in the yard across the street. Runs, drives,and bush hog works. Won't lift though. Odd plumbing job.Any idea why that hose is running to the side of transmission?? Will figure it out, I guess. Odd front tires!

I am guessing that line is a return, but I can't really see where it's going. It looks like a homemade 3pt hitch, so if that line comes off the hydraulic lift cylinder, then it is most likely a return line.

If it is set up so the factory hyd pump does the lifting the PTO has to be engaged for the hyds to work. Also the hyds fluid comes from the transmission so the fluid lever needs to be full or no hyds. My 1946 C has both a front snow plow lift and a home made 3 point. The front lift I have is a copy of a picture someone sent me years ago and fits both the B and C tractors and if handy for lifting things and moving them around
 
The hydraulic system uses the PTO housing as the sump, and has small high pressure cylinders. The gasket between the PTO housing and trans has a dam to pin fluid in the PTO for the pump to draw on. When using larger cylinders, there is not enough fluid in that area, so people remove the dam and slightly overfill the dam to insure fluid at the pump.
Original cylinders are something like 1 x 16 if I remember right. A 3x 12 uses a lot more fluid and needs a much larger line for returning fluid quickly.

My B solved that with live hydraulics via a GM power steering pump driven by the crankshaft.
