So the D14 was designed to replace the WD45. So in the real world how do they compare? I'm betting a lot of you have both or have had both. I have a WD45 and D17's but I've never run a 14 or 15.

The D17 replaced the WD45 .(226 cu in) A few years ago we had 450 bu wagon loaded with corn and hooked our D15 series II to the wagon. Put the tractor in 2 nd and let the clutch out
and it just spun. Unhooked and hooked our WD45 gas to the wagon. Put 45 in 2 nd gear pulled back on the hand clutch and the tractor took off moving the load.
The D14 is a nice tractor with the high low range but the WD and WD45 will out pull it.

We replaced a WC with a D14 and the 14 handled combine with pto better than the WC but the WD45 is a lot bigger tractor and i would compare it with a D 17.

I guess you could say the D14 replaced the CA. That would be a better comparison than a WD45 and a D14.

The D14 was not meant to replace the WD45. The 35 hpD14 never had the weight or power of a 45. The 46 hp D15 II is a better comparison, but most believe it was not as strong as a WD45.

I stand corrected. But I thought AC's advertising said the new D14 was the replacement for the WD45 and the D14 was introduced before the D17. Also I thought the CA was sold along with the D14 before the D10 and D12 were released. Don't have any books here though and my memory isn't what I remember it to have been. Our WD45 was never close to a match for the power of a D17 even with a D17 kit in it, or the comfort level of the D17... well the 45 doesn't really have a "comfort" level. LOL I like the 45 but I love my D17's, theres been quite a few posts recently about D14's and that's what got me thinking about this. I keep thinking a D15 or a D14 might be a nice addition to the collection.

If I remember correctly, Norm Swinford's book says that the D 14 replaced the CA, and the D 17 replaced the Wd 45

Did AC consider the D14 a "three plow" tractor like the 45 was? I thought AC called the D17 a four plow tractor. This might be the cause of my confusion...

Dave, they did not consider the 14 a 3 plow tractor, the exact terminology was that it was to say, not quite a 3 plow tractor. That is why it was short lived, and was quickly replaced by the D15. I do have a D14 and a D15 and like em both. Darrel

Actually the WD45 was called a 3-4 tractor, and the D17 a 4-5. There is literature showing the WD45 pulling 4-14s and a D17 with 5-14's. I pull a mounted #64 4-14 most places with a balasted WD45 that dynos 43 HP. Dennis Anderson from Ridott, IL has plowed with 5-14's behind a D17. A properly adjusted and bright plow, and a working traction booster system allows you to add the extra bottom.

Most problems can be solved with the proper application of high explosives.

The new "replacement" model always had more power than the model it replaced. That's why you see the up in plow size between models.
The experimental models that led up to the D14 look a lot like a CA.

D-14 vs WD-45
My brother, Warren, bought a D-14 new. The salesman told him that it was
at least equal to a WD and probably as good as a WD-45. The D-14 was a
very nice tractor, but if you started to lug it, you had better be reaching for
the hand clutch. So. Warren was never really happy with the D-14, even
though it never had any problems. After a few years, Warren traded it for
a 450 Gas(hog). He finally got the 450 weaned down to 4 gallons an hour.
A personal story, I was home from the Air Force on leave, and plowed
almost all night with the D-14 and a 3-14's A-C mounted plow. I finally
had to quit when I would wake up when the tractor started to bounce
on the end rows. (I would turn the front wheel slightly against the furrow
wall and then could take a little snooze, when I was going across the field.)
We do take some chances sometimes, especially when we are young and
invincible. I thought that when I got old, I would get old and wise, but I just got old.

According to Norm Swinfords book "AC Farm Equipment 1914-1985".
The B was replaced by the D-10,the CA by the D-12. The D-14 replaced the experimental model CA30,and model 101. Also he said in the book, "that the D-14 had the same power as the WD and it was not quite a three plow tractor".The D-15 with 18% more power replaced the D-14,and the D-17 replaced the WD-45.
