I have a D-17 Series 2. My question is when I depress the clutch i can lower a implement but unable to lift it while the clutch is engaged. I have to take it out of gear and release the clutch to raise implements. All of this is while stopped. Is this normal?
 

Clutch is disengaged when you push the pedal, engaged when the clutch pedal is not pushed. The short explanation is the hydraulic pump is driven by the shaft from the clutch going to the transmission. So pushing/disengaging the clutch stops the pump turning. You can stop the travel of the tractor using the power director clutch, without using the foot clutch, to keep the hydraulic pump turning.

Here is some info from a D14 Operator's Manual, I expect the D17 manual will be similar.

Is this tractor new to you? I would recommend you get a set of manuals (Operator's and Service for sure, Parts optional) for it. You should be able to find good used OEM manuals on eBay, they are usually better quality than most of the new reprints. AGCOpubs.com is where new Allis Chalmers manuals are sold. If I remember right series 1through 3 are pretty much the same and use the same manuals. Series 4 had most if not all three manuals of its own due to changes made for Series 4.

Here is a link that will get you to the AGCO on line parts books and it has a link to the publications site.

Normal. The pump is after the engine clutch. As others have said, use the neutral of the hand clutch to stay in gear and use the hydraulics.

Allis was way ahead of a lot of tractors with their traction booster, and fuel economy, also the toughness of the over all tractor, and the early application of power adjust wheels. I realize that they wanted to sell, proprietary equipment, so forego a good 3 point hitch, for years, have to wonder, why they stayed so many years with the hand clutch, or the power director, instead of independent PTO being as Cockshut , had shown the way!
 
I agree Ralph. They were way, way late getting an independent PTO setup. Oliver had it for sure on the Super series in 1954. Maybe earlier. When did Cockshut come out with it?
