I bought a 420 without a serial no. Looking at the parts catalog I can't tell if it's a special utility {I} or a row-crop utility {W} model. Looking through out the parts catalog and when a part is not common to all models it all ways list the special utility and the row-crop models together. What is the difference between these two models? It has been repainted all green.

In your parts manual, look up "front axle". You'll see the difference between the I and the W in the tie rods.

Also, if the casting number on the transmission is M3158T, it's a 420W with a serial number prior to 100000.

Hillory, i dug a little deeper. althuogh your tag is missing, you should be able to locate the holes where it was mounted. this is right out of the book. on 420 series tractors 80001-100000 the serial number is located in the center on the left side of center frame. on 420 series 100001-up, the serial number plate is located on the left-hand upper side of the bell housing of the center frame. "left side" is battery door side. if its in the first location, it can only be a 1956 model. if its in the second location it could be a 1956,57,58 model. go to ytmag web page click on serial numbers and you'll see how this could happen.

first, a 420-I is an industrial(all yellow)model. the 420-V is the "special", designed to cultivate crops in their late stage. it stands tall but not as tall as the 420-H (hi-crop). i own a 420-W. it is a low built tractor and the only 420 model with a square axel tube(housing)that incase the two front axels. if you can get access to a service manual,#SM2019, it has very good pictures and discriptions of all the 420 series tractors.
read my posting on 9-27-00 about 420 paint, ToddT
has cleared up that question. good luck.
