You can get down pressure, but you'll have to make a solid flat bar to replace the loose chain, it's an easy alteration but worth it:
Here's a response from Garry in Canada on the measurements for this part:

From my notes.
Lift link 7706 1/4"x1-1/4" flat stock 12-1/2" OL 3/8" pins 11-1/2" c/c, Pins stick out 5/8"
You remove the mower lift arm and chain and install the long link to the lift arm on the lift.
I think I made one of these. Drilled holes in the bar for 3/8" bolts about 2" long. Cut the threads off and drilled small holes for quick pins. Welded the heads of the bolts to the back side of the flat stock with each facing opposite directions. This way you do not need a large offset in the bar to line it up vertically. The small pin holes are 90 degrees to the bar with a good chamfer on each hole so the pin easily finds the hole. That way I know where the pin holes are and can install the pins blind.
