Series 3,4 etc D17

Kevin

Here is a summary of one of my previous posts:

1957-60: Series I (orange wheels, orange diamond-mesh grille, round muffler, grille-mounted headlights, oval model decals on side panels; 1959+ models had 3-bar black grille and slightly different decals)

1960-62: Series II (white wheels, white square-mesh grille, round muffler, metal hood decals, square model decal on lower half of gas tank, still had grille-mounted headlights I believe)

1962-64: Series III (white wheels, white square-mesh grille, oval muffler, full-length white hood decals, fender-mounted headlights, mechanical updates, engine updates)

1964-67: Series IV (same appearance as Series III, major mechanical updates such as gear driven hydraulic pump mounted where belt pulley used to be, provided for full-time live dual hydraulics whenever engine was running; Category II 3-point hitch option; external rams on rear lift arms)

These are the major highlights. I am recalling this from memory, so there may be a few things missing. The D19 was produced from 1961 to 1964 - no series designation. The D17 diesel used the 262 diesel throughout production (1957-67), although various design improvements were made to this engine in later models. Ditto on D19. The additional HP of the D19 diesel (66 HP vs. 52 HP on the D17 diesel) was obtained by turbocharging the 262 diesel in the D19. The 262 gas in the D19G achieved 71 HP.

Thanks again for the response. Is there any posted info that provides a detailed summary of the various D17/19 series--like what improvements each one brought and what year models have them?
If I could get that info, then I'll know more about what to look for. The obvious answer is to go for the '64 model--isn't this the last year of the D17/19's with the 262 cu. in. diesel?

Another concern I have about the AC tractors--my Nebraska Test Lab book (1950-1975 tractor test results) indicates that all pre '67 AC tractors used what was called a "snap coupler" instead of a standard 3 Pt hitch. If I get one of these D models, is it a major job to convert to a standard 3 pt hitch? I believe all my implements are cat III.

Thanks for the tech info--that'll help alot. I'll check out your site as well.

To Dave: I ordered the AC book by Norm Swinford on Monday. Looking forward to much reading.

I'm still trying to run down a diesel D17 or 19. Found a decent price on a gas D17, but I'm still considering it.

Thanks for the help.
