I have owned several AC D series and hundred series tractors and none had a differential lock. I am curious: did AC make an ag tractor with a locking differential? |

although an imported tractor, the AC 5040 had a diff lock. I would guess a 5050 had it too, but not sure about the smaller 50**

| The mighty One-Sixty would have been the first "A-C" with a diff lock. |

| When I was in an ag class in high school, the teacher said something about a differential lock, and I was clueless. He laughed at me. I said there weren't any on our tractors. He thought I just didnt know any better. We were running 220,210,XT, D-series tractors. |

6000 series has diff lock. Still a gray area since it is a Fiat transmission and rear end. However, it was still built in West Allis. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Yes, the older AC tractors did not have differential lock. Probably became available around 1964-65 on JD 4020/3020s, as optional equipment? One of Dad’s 4020s(the 68’) had it. It was very helpful when plowing, planting, & pulling gravity wagons. My first opportunity for operating an AC differential lock was field cultivating with a 1974 AC 7050. AC offered it in 1973 as standard equipment on both the 7030 & 7050.  |

| Differential lock is usually pretty durable on most tractors if used like its supposed to be used,wouldn't have to be too good to outlast a ED40. |
