| I have 3-175s, 2-170s and 1 one seventy. 1-175 has a D after serial number, 1-170 has a D after serial number, one seventy just numbers. tractors are numbered from 1967-1981. just trying to understand the reasoning behind the differences in the number 170 is of course a diesel, all 175s are diesels. what do you think is the differences in the numbering of the tractors |

| I sure don't understand your question. In general, all the DIESEL tractors always had a "D" at the end of the numbers. Not always, but generally. |

When the 175 came out, as a diesel only, did they quit adding the D to the sn? Then they later introduced the 175 Gas and then had to go back to noting the difference on the sn? Maybe someone has swapped gas to diesel. What I'm getting at is there was a time when only diesel was available, so maybe they didn't see the need to note it's diesel, since that's all there was, during that time frame. Who knows, post up the serial numbers of them all and someone will know if they fall in that window. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

| my question is in regard to d series had D after serial denoting diesel. middle 170 diesel has D, 1981 175 diesel has D, but the others do not have D denoting diesels. just wondering why their was a change in numbering. |

| The employee operating the serial number stamping machine could tell us, but doubt that he/she is around any more. There was somewhat of a good reason in the case of the D-17, because the gas/LPgas tractors had a longer clutch shaft than the diesels, so it would have been of great importance when assembling to know which torque housing you were working on...gas or diesel. |

My 1977 175 has a D at the end of the serial number. There is a possibility that a couple of your 175s might have been originally gas, but then replaced with a diesel at some point in the last 40 years. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

| back ground on one 175 came from tractor jockey 30 years ago. 2 of 175s without came one of my friends when they settled his estate. his father bought one new, he bought the other one new himself. they are both diesel from day one. I worked for them back in the old days, thinking why couldn't we get a new tractor. |

| Just looked at ours. 1979 175 diesel. No D at the end. I'm sure it came from the factory as a diesel. |
