AC D17 Tractor What's it worth??

I usually post on the Farmall Board, as I am and International Guy. However, I've been looking for an inexpensive loader tractor and found this Allis D17. I can buy the tractor for $5800 with two new Good Year tires on the back. The tractor is a 1962 model (gasoline) which I think makes is a series II. The loader is an AC model 400. It runs perfect and everythink works, good oil pressure and there does not seem to be any leaks. It has power steering. The loader has a separate hydaulic pump on the front of the engine and there is a set of remotes on the back that seem to be connected to the loader hydraulics. There is another remote that seems to be connected to the tractor system that runs the rear lift. I think this would be a high pressure AC connection. All the fluids look good and everything is full. Looks like tractor fluid everywhere. The tach shows about 2000 hrs, but it is not working. The only thing I see wrong is that the power director seems to need adjustment as I believe the tractor is supposed to stop when in the middle position. You can stop it, but you have to hold the brakes and it sounds like there is a load on the engine when you do that, so something must be dragging. Works good in both high and low range.
So.... is the $5800 a good price??

In my area that would be more like a $3000 tractor maybe a tad bit more due to the new rear tires.
 
I'll go somewhere between Old and the asking price. If that tractor were a series 4 set up exactly the same, it'd be close to a $5,800 tractor. I would still think she'd be worth all of $4,000. I'd love to own it's twin sister, but I'm somewhere between $3,000 and $5,800 short .

The D17 appears to be a nice looking old tractor but your description of the power director clutch causes me to have some concerns.

It’s not a matter of a simple adjustment shims must be properly removed and added to get proper clearance for the high and low part of the clutch..

Because of the Power director issues I personally would not want to pay $5800.

I’m thinking $3500-$4000 tops; for my money I wouldn’t want to go over $3500

If the power director clutch needs work it could be $500-$2000 to fix it depending on what it needs. The tractor would need to be split which isn’t a bad job.

Problem is once you get it apart you may find more trouble.

On the good side The D17 can have a 3pt made for it and a separate valve 2 or 3 spool open center valve with 1 one way spool (for the rear lift) and the other spool or spools can be 2 way.

This valve can be plumbed in to allow for 2 way hydraulics.

PS. Where does the hydraulics for the pump get its oil?

If its from a separate tank your ok but if its from the reservoir of the tractor maybe not so good because you cant add a spool to the current tractor hydraulics
 
The loader has it's own reservoir in the loader frame. The tractor already has a three point hitch on it. There is a two way hydraulic remote valve and connections on the back tied into the loader hydraulic system.
 
Everything you have said is a plus to the value of the tractor.

Personally i still question the Power director Clutch.

There is a chance it was miss-adjusted and all that is needed is a proper shim job.

The value maybe a tough call.
 
I have a series 1 D-17 I'd sell you for $2500 and it has a 3 point set up. Easy start to boot but but ugly LOL
 
Ya this one I have is on ruff shape when it comes to the sheet metal but runs good. Pulled it out of a fence row where it had been parked for years and the engine was full of mouse nest stuff. Purrs like a kitten now and I use it for odd jobs. Brush hogging raking hay etc
 
Some info given if off base a bit. Hard the say if anything is wrong with the power director, somebody experienced with a D-17 could tell you in an instant if it is dragging more than it should. They all drag some in neutral and you will have to hold it with the brakes. With cold oil they all will load the engine just a bit and you will need to use brakes more than slightly to hold it from moving depending on what gear you have it in. With hot oil the drag should be negligible. Move the lever either side of neutral a bit and see if it eases the drag. If so it has been shimmed incorrectly. If it has been used hard and or run without oil the plates may be warped and it will drag real hard.
 
After talking with some of my Allis Chalmers friends, I concluded there is nothing wrong with the power director. I wiggled that lever around all over and there was no place where the drag was less plus it was in low gear and cold when I was messing with it.
 
D17 are good little tractors, I still own one and my family still has a D19 and a WD.

I have split D17’s, over-hauled the engines and rebuilt both the Power director clutch and the plunger pump.

Normally a properly functioning Power Director clutch will not cause a noticeable heavy load on the engine.

From the original description you gave it sounded like a miss adjusted power director clutch or has one post said it could also be a warped plate.

But…
If you’re satisfied with the condition of the tractor then it comes down to price. After-all you’re the man buying the tractor and its hard to diagnosis a problem setting at a key board.

P.S>
D17’s are very unique in the fact that a kit used to be available that allowed a 2 or 3 spool hydraulic valve to be plumbed into the circuit of the plunger pump very similar to that of a D19. (Most people don’t know this fact)

The only draw back to the kits was the lever had to be in the raise position to make the hydraulic valve function and you would lose the tractors Traction boost feature.

Good luck…
