What is this for?

Hi I have a question about the vickers  transaxle on my homelite t-16h.

what is the shaft sticking out of the hydro pump for?

That's for leaking..

Seriously though it's called a pintle shaft.  Notorious for leaking on those Vickers hydro units.  @Chris727 & others have had these repaired.  To repair them properly, the casting is line bored & bushed.  I've never owned one of these so others can verify.  But in the later models, there was some type of seal & maybe bushing from the factory.

thanks for the info i will look in to fixing the leak 

does the pintle shaft have a purpose though

Without ever owning one, I would guess that it slides fore & aft when the tractor is moved forward & reverse thus diverting the hydraulic fluid in different directions?

As @ShaunE surmised, it diverts the hydraulic fluid for forward/reverse and speed.  It is rotated by the lever attached to the front of the shaft:

Based on this pic of a 3416 Vickers (latest version) you seem to be missing a bushing or seal on your pintle shaft:

In my experience, the front of the pintle shaft is usually the leaker (lever forces wear the bushing).
