| I have seen several pictures of WCs and WDs that clame to be Allis made high crops. Did Allis make there own high crop at any point? If so where can I find info on them. The pictures I have seen are spot on matches to my WC which was purchased from Thomson Machinery in Thibodaux, LA in 1947 we still have the original invoice. That doesn't mean that the high crop conversion was done by Thomson. I am curious to find out. |

From what I understand, all of AC's high crops were made by mfrs other than Allis. Thompson was a big contributor to the AC high crops. ------------- 39'RC, 43'WC, 48'B, 49'G, 50'WF, 65 Big 10, 67'B-110, 75'716H, 2-620's, & a Motorhead wife |

According to Pop's Price Book the D-17, D-14, D-12, and D-10 were available from the factory (special Order) as High Clearance units. Since the price book is dated May 1960 and was superseded by a larger three ring note book price book which I do not have. It does not show the later model tractors so I cannot confirm them. I know some units were made hi-crops by Thompson. Since we did not sell them I am not aware of Allis Chalmers having a hi crop option for the lettered series tractors (B,C,CA,WC,WD, U,UC,and WD45). From reading MR SWINFORDS's records of serial numbers it seems that there were no separate serial number section for hi-crops made by Allis Chalmers. It appears if you wanted a high crop you specially ordered it. Hope this is some help. Good Luck! Bill Long PS: I watch the auctions on RFD TV where some of the John Deere Hi Crops are sold and they specifically confirm the number of units that were made. It appears you can not do that with Allis Chalmers |

Wasn't there highcrop options in the dealer parts book for the WD/WD45? (224830, 224835) Allis also made high clearance Bs as well (potato special and asparagus special) ------------- Can't fix stupid |

Hi-crop steering parts are shown in the parts books for the D-10,12,14,17, & 19 WC,WD, & 45 don't refer to "High clearance" in the parts book ------------- Allis Express North Georgia 41 WC,48 UC Cane,7-G's, Ford 345C TLB |

Of all the high crops I have only my 1948 WC is factory. It has WF front wheels and UM rear wheels. I also do have the potato and asparagus B tractors that are factory made. ------------- Allis Chalmers Museum, Paris, Il.http:// www.allischalmersmuseum.com 217-275-3428 |

I'll add my understanding of A-C 'High Crops'. To my knowlege all A-C High Crops were produced by Thompson prior to the D-17 IV. A-C produced 'High Clearance' tractors prior to the D-17IV that came with special tall rear tires and rims as well as tall front axles or taller single fronts. There were also some conversions of regular tractors to 'High Crop (Clearance)' by the A-C plant in Oxnard CA. The true factory 'High Crops' had special rear axles and final drive drop boxes and in the case of the D-19, 7000 series, and 8000 series had final drive drop boxes instead of the standard straight axle along with the very tall front axle. ------------- Nothing is impossible if it is properly financed |

Here The way I see it. Allis supplied Thomson with Main body of the tractor. Thomson built the rear wheels cast centers and front ends because this what was needed down south to take care of their crops. B-C-CA-WC-WD-WD45-D 17 all the way up to series 3. UC these type of engine used thru the years UM engine and D-17 gas and diesel motor- 2 and 3 cylinder Detroit motors. California tractors- Oxnard built the rear wheels made the front taller to fit their needs out west. This my Question on the regular tractor did Allis actually build the spin out wheels or did they have supplier build them? Because I see lot of tractor with the same rims. WD parts book show rear wheels that are 38" had custom 8 bolt to 9 bolt adapter. This wheel is the same used on a Cockshutt. WC parts book show the Cast wheel with 36" rim with angles welded. Used the WF styled front wheel. The rear end should have the slower ring and pinion. only time it has not been in my tractors if had been changed out because went bad. Also I own WC high crop with Cast center that Thomson built these are flat and say Thomson on them. So they all are Allis tractors in the end in my opinion. |

Allis engineers invented and got patent for the spin out rims. They then sold it or gave Motor Wheel (division of Good-Year) the rights to manufacture the spin out rims. There must have been a number of years that A-C had an exclusive on the spin out rims because these rims didn't start showing up on other brands until the late 50's. A-C likely got a royality on every spin out rim produced by Motor Wheel ------------- Nothing is impossible if it is properly financed |

Nice straight D-17 factory 'High Clearance! I changed the rears on my D-17IV diesel to 38's about 15 years ago for row crop cultivating kidney beans. The rims and centers are the same as a M-F 65 'High Arch' which is what I used. I don't have the tall front axle but may add a 16" spoked single front. ------------- Nothing is impossible if it is properly financed |

My Grandparents raised me, as my mother passed away just 6 weeks after I was born. My Dad lived across the country road where we lived. My Grandfather was a Sugar Cane farmer for years. His first tractor was an Allis Chalmer High Crop B, Thompson conversion. The farm was a 400 acre farm. His Brothers followed and each bought the same tractor all with the Thompson conversion. My Grandfather soon bought another B, without the conversion for shorter crops such as sweet potatoes. The High Crop B would pull the front wheels off the ground a lot easier then the regular with the lower back tires and lower clearance front axle. The High Crop B's put in a lot of days of hard work in on the farm for many, many years. They were used to do work that should of required much larger tractors, but were the best for the times. With the taller rear wheels the High Crop B covered the same ground in first gear as the regular B did in second gear. With that said, the taller rear wheels reduced the pulling power from initial start, but once rolling they pulled like big mean tractors. Spinning the rear tires were not seen often. Ground had to be real soft for that to happen. Those taller rear tires lasted much longer then the lower tires on a regular B, which had no problem spinning them. My favorite of course was the High Crop B, as I was just a kid, driving that tall tractor made me feel big and Bad !!!!!!! The High Crop steering was not as easy as on the regular B though. Power steering wasn't heard then. Pop had given me his High Crop B which I used for a few weeks working on my two acres where I live now to get the ground drained and reasonable level. Once I was done I had no place to store it so returned it to him. He seemed to be heart broken that I returned it since he was retired and due to his and my Grandmothers health also needed to move off the farm to a place more suitable for them. They needed all the money they could get for their belongings so they could live more comfortable in their last years. All his farm equipment was sold, wish I knew where the Old High Crop went. Not many survived as they required special tool bars and implements. My Grandfathers implements were Thompson conversion implements, Allis Chalmers and many were homemade of his own design to fit his needs. I have to admit some were smart designs. He also designed a tool to remove the original rear axles which had a center nut on the end to replace with the newer rear axles made to fit the Thompson center that would not wobble as the wheel turned. With his tool he designed it saved taking apart the rear housings, saving a lot of labor. The Allis Chalmers dealer in our area actually paid him to teach them how to do it. The regular axle with the nut on the end had a tendency to work its way loose and start to wobble, then shear the pin and start slipping and quit pulling.
