Was there any major problems with this tractor? What kind of price will it bring at a sale? What is the HP of it?

Hey guys, I've got 2 D-21s; and I'm negotiating for a third that's up in Canada....I rebuild ALL
piston engines and have personally rebuilt over 218 different tractor/crawler/dozer/truck/car Diesel engines...I dyno test EVERY engine I can get hooked up to my dyno; a Hot AC D-21 Series II
(with a GOOD, tuned turbocharger) will pull BETTER than factory specs...They are one of the STRONGEST Diesel engines that I have EVER tested. The D-21 was the first non-4 wheel drive tractor DESIGNED to pull SEVEN (7) x16 inch PLOWS at whatever depth the operator wanted to plow. One of my D-21s
pulls 185 PTO horsepower; I have pulled 10-18 inch plows @ 8 inch depth on sod ground and I won a CASH $500 bet in the process from an old-timer John Deere guy who STILL can't believe it!!!

I've seen prices ranging from $5500 for a redone Series I to $11,000 for a fully-restored Series II machine. The Series I had 116HP and the Series II, which had a turbocharger on it, made 127HP(if memory serves). Price, of course, depends on condition, location, etc. I think the D21 is one of A-C's best-looking machines, and I plan to own one someday. Maybe Santa will bring me the money(hahaha).

I think the early ones were around 100HP and the later about 120HP, just guesses. I seen someone say the rearends didn't hold up to hard use but I don't know that for a fact. I see them in the paper every now and then for about $5000+. I think alot were built without all the goodies on them. Like 3pt and pto. I've also seen some advertised for as high as 15,000.

Back in 1985 my brother and I were going to build a 1967 D-21 Series II into a Prostock puller.Well it never happened so we sold it to a neighbor (6) miles away.The owner passed away in the early 90's and the widow let it sit for (3) years.In 1996 I could have bought it,6x16 AC plow,and 16 ft AC chisel for $3500.It hadnt run in (3) years and had tranny troubles.The D-21 is the best looking AC ever built.I have original sales lit on both versions.3 or 4 new ones were sold in our area .They are sure hard to find these days.I did know where several were at but they are gone now.Lots of 21's were made into pullers and quite a few are still pulling yet.

Ron; call me anytime @ (801)920-1214; leave a VoiceMail for RF Walker I'll return your call. Seven bottom
plows are HARD to find; I see them sometimes,
you should consider 6x18s or 8x16s, plenty of those in my area (Oregon; Willamette Valley). Call
me and we can chat.

Today's Featured Article - A City Guy's First Tractor - by Fred Hambrecht. After living in apartments in Atlanta for more years than I care to remember, the wife and I decided to move to the country. Humming "Green Acres is the place for me..." we purchased a 29 acre tract about 60 miles south of Atlanta. Next came the house, I could talk about that ordeal for another two weeks... But, I want to talk about my tractor! We didn't even own a lawnmower, and all of a sudden we had enough grass to feed all the starving children of the bovine world. Naturally, I talked ...
