Hydraulics on Oliver were first used on the Fleetline 66, 77 & 88 tractors. Three point hitches were available for those tractors.

Sure and it was a live PTO, but it was an option.
We were recently presented with some possibly conflicting information. The Cockshutt site claims that the Cockshutt Model 30 sold starting in 1946 was available with Live Power Take Off (LPTO).
Melvin Goodknight of the [email protected] pointed out that some Hart-Parrs of the 1920s had LPTO. The critical difference was that dangerous external shafts were used to get power from the front of the engine or the belt sheave back to the hitch area. At least one of these had a hand clutch to engage it.
I do not know if an official name exists but I would use the term "Rear Exit PTO" for a PTO shaft that comes out of the rear tractor housing in the vicinity of the hitch. We are still fishing around for which brand first had a Rear Exit Live Power Take Off.
We know the 1939 Ford-Ferguson 9N had a rear exit PTO but it was not live. Its sons, the Ford 8N and Ferguson TE20 as well as the TO20, and TO30 did not have LPTO either. Its cousin, the David Brown VAK1 had a rear exit PTO but as far as I know it was not LPTO. The 9N's grandson, the Ford NAA, had LPTO. I do not yet know the first Massey Ferguson model to have LPTO.
In YTMag, JSchiebert posted that the Oliver Fleetline Series (1947 - 1954) 66, 77, and 88 came standard without PTO but had rear exit LPTO as an option. The same tractors had three point hitch as an option also. This still gives Cockshutt the edge on the rear exit LPTO. This Oliver site shows an Oliver 66 with three point hitch.
It's looking to me like the Harry Ferguson design team were not doing the best possible job of keeping up with improvements being made by competitors.

"Independent" PTO, actually- PTO is a lever that turns on PTO regardless of what you're doing with the tractor clutch. "Live" PTO generally refers to the rigs that have a two stage foot clutch- depress it partway, and forward progress of tractor stops; depress the rest of the way, and PTO stops. Independent is considered by most to be superior (especially for hay baling), but either will work fine for most purposes.
S55 also had "live" hydraulics (PTO need not be engaged for hydraulics to work).

My dad was an Oil Pull man. He had a piece of literature on where you go order a PTO for some models. Also the Cockshutt 30 was first introduced in 1946 a little ahead of the introduction of the Oliver 88. Some literatue used to say Oliver had the first live PTO on an American built tractor. The 30 being built in Canada. The Nebraska test of the Cockshutt 30 made two first. The first tractor with a live PTO and the first tractor tested made in Canada.
Was the PTO on the Cockshutt 30 a two stage clutch or an independent PTO type?
Did the cockshutt 30 have an optional 3 point hitch, auxiliary hydraulics, and/or live hydraulics?
Is the Cockshutt 30 PTO shaft located in a standard location?
Since the Oliver 88 had optional 3 point hitch I am assuming that the PTO shaft location was in what became the standard location.
I am inpressed by the Oliver 55. I used to know some people who owned one.
Was the Rumely rear PTO an aftermarket kit?
