They all have a float. Press the boom down pedal hard with you toe and it should stick in this position. If it does not stick the detent in worn out (parts cheap but no easy to work on) When you push the pedal fully with your toe you will hear the engine stop labouring trying to pull it down.
I'm not sure you would need the float for the rake the only real weight on the front of a 743 is the attachment, just take it off and see how easy it will wheelie.

The detent is actually part of the control block. It uses 2 metal balls with a spring to hold it in position. I have had this not work before due to wear in the linkages. If they are very sloppy you don't have enough travel to push the spool far enough out for the balls to lock in the groove on the housing.
As Ken said, use your left toe and push all the way forward, you will hear the oil going over the relief and then it should click and lock forward. Tilt the bucket down and the arms should lift up. This is float position.

I wasn't going to complicate it :) but yes there are 4 balls and 2 springs but you only need to worry about 2 balls and one spring, the others are just used as a guide and never seem to be a problem.
