SMTA Lift All

Uncharted waters for me here...

Just spent a LOT of time mounting a #115 mid-mount mower on a SMTA. Have it all set on there and I am ready to go EXCEPT I have connected the one-way cylinder and things are not exactly going well. I had my choice of two outlets on the left side of the hydraulic fluid reservoir. I took the upper one as it was easiest to get to around the clutch pedal. Unlatched the lift-all control rod and pushed it forward and the mower lowered to the ground and the bar extended into cutting position. Lifted up on the control and pulled it back and nothing happened. Re-read the manual...seem to be doing it right. Are there any common/likely mistakes or problems with what I am doing? Any and all help/suggestions appreciated!
 
It should work on that port if the unit is building presure. If you have the remote control valve on tractor it needs to be locked in to have pressure on the liftall.
 
Thanks! I had forgotten about that latch and missed it in the manual. I also see the fluid is low so I will fill that in the AM. Hoping that does it! If no then I will have to look farther. Little bit of a problem as I apparently never ordered a service manual for this tractor. Have them for all the others...don't know why except this was my first old tractor and I have never had to service anything on it. Don't even know where the pump is!!!
 
I gotta pull thru all these manuals and make sure there is no service manual for this tractor then get one ordered. The MTA has two hydraulic systems, lift-all and the remotes. Is there only the front mounted pump or is there another? I see lots of references in the archives (yes, I looked!) to a "belly pump" on the older M's. If the only pump I need to worry about is the front one, then I am just doing something stupid because that pump works fine.
