How is the market doing on D21s. I have let the bug get ahold of me and have narrowed down my search and found a very early SN 21 that is absolutely stunning. Part of me says get all over it, your not getting any younger,67, I have worked and saved all my life, saw parents lose 900 acres in 1984 and that changes outlook. A other part of me says why.

| I have always wanted one. D17,180,200,7060 is my background. Started looking recently and found out it's a slippery slope. |

| The worms are going to eat you at the same speed when you die if you buy it or not. Do what is going to make you happy. Financially, i don't think it is a terrible investment |

| Some have been kept up and are pretty sound. Others are a pig with a coat of new paint slapped on them. Beware !! A "very early" serial number (to me) would be a non-turbo 103 PTO HP model. If it has the turbo/engine oil cooler kit added on, that's what it is.....an added on turbo kit from A-C which was offered but it wasn't on it from the factory. The engine s/n tag is on the left rear side of the block. The chassis s/n is very close by stamped into the bell housing. If the chassis is D21-1001, the engine is probably 3D-1003 or 3D-1004. Those engines in 1963-64 were almost exclusively used in the D-21 tractor. Finding an engine s/n that indicates it is probably the original engine (to me) makes it worth more $$$$$$ when you go to sell it on your estate sale. I feel a PTO makes them worth more, as does a factory 3-point hitch. Make sure the top link anchor holes aren't broken off as that is a deduct in value. 18.4 x 34 tires (for me) are a huge deduct. 24.5 x 32's are muscle tractor material. 18.4 x 38's are in between. I recently saw one for sale that originally had 18.4 x 34's when new, but somewhere in the last 60 years had the rims widened and 20.8 x 34's mounted. They stand as tall as 18.4 x 38's (a good thing) but resale wise, better than the 18.4 x 34's but not (to me) as valuable as the other two sizes. A curved front "starter" weight is a great thing !!! Fenders skirts also are desirable. Rear axle seals that aren't leaking a puddle wherever you park it is also a good thing. If it runs well, and you drive it....you'll get hooked. They were one of a kind !! |

This is what iam talking about. I can't hardly believe what I see when I look into a mirror. All of a sudden iam what I called an old man. But here I am, still taking what life has thrown at me, lemonade out of lemons I have several times. I don't want to bring bad luck as bad luck has followed me at times.
