What model AC first appeared with both live PTO and live hydraulics?

The first model I acan think of with independent hydraulics and PTO is the D21 in 1963(?) The 180, 190 and 200 all had independent hydraulics but the PTO shut off when you pushed the foot clutch in.

Thanks to John and JMS for your responses. I'm familiar with both the WD and WD45 clutch arrangement and the D17 Power Director, having spent some quality time on both, but don't consider either arrangement live PTO. The model I'm wondering about would have operational PTO regardless of whether the foot clutch was engaged or disengaged. Sounds like that might have been after the 190 series?

What you are wondering about would be termed 'Independent' hydraulics and pto. D17 Series IV had the independent hydraulics, with the pump mounted in the same location as the belt pulley on earlier models. 'Live' hyd and pto started with the WD in 1948. When both were independent, that came much later.

The D-21 we had was live hyd and PTO. In our neck of the woods (upstate NY), because of the hand clutch arrangement, WDs were referred to as "continuous" PTO and hyd, as compared to live. Sort of an interesting nomenclature in that IHC Ms with the M&W hand clutch were advertised as "live", and of course, so were the hand clutch JDs after the letter series. Prejudice delivers some interesting conflicts.

JMS is correct, as long as you both have the same idea as to what LIVE power is. The WD came out in 1948. It had the hand clutch that would stop the tractor movement without stoping the PTO or the hydraulics. The CA came along in 1950. AC used this same arrangement up through the D series tractors and into the 190 series at least. The D-17 series IV was sort of an exception. I believe it had the 2 stage foot clutch in addition to the hand clutch, that by then was called a power director and had a high and low side in addition to neutral.

If someone insists on thinking of live power only via a foot clutch, then I believe the D-17 series IV would be the first.

The simplest definition of live power is exactly what was provided by the 1948 WD. You can stop wheel motion of the tractor while hydraulic and pto operation continues. About a week ago, on this forum, I was insulted and cursed at by people who had other opinions. I have yet to see any AC tractor with a two-stage clutch to provide live power. In the D17, live power was provided by the Power Director, until the Series IV came out with the independent hydraulic pump.

I think that would be the 1948 WD, via the hand clutch. Don't remember when the CA came out, and on early models, you might not find the hand clutch- but it also operated differently than the WD.
