I picked this gem off of Craigslist because the lowered look caught my eye. I thought it might be one of those orchard tractors converted in Canada, but i'm not so sure now. It's serial # 43742. It has the final drives rolled forward, and a solid front axel. The steering shaft has been shortened about 10 inches. The torque tube is standard length. It retains the traditional B fenders. Hand brake levers are different than a normal B. There is no belt pulley but a P.T.O that just sticks out of the rear end and not combined with a hydraulic pump. It has a diamond plate platform that is formed around the torque tube with a place to stash the battery out-of-sight. The clutch pedal looks more automotive than agricultural. All of the modifications have been done very cleanly. This is in no way a cobbled job. A Woods belly mower was installed on this tractor and does not look like it had to be fabricated to the tractor. I probably can't call this an IB, and it is no where near a row-crop B. So i ask of us fellow A-C forum members: 1. Has anyone seen another tractor similar to this? 2. What would be a correct title for this tractor? B-Low? B-Industrial Conversion? B-Municipal? Check out the pictures and please give me your thoughts. Thanks!           ------------- Pre-WW2 A-C tractors on steel wheels...because I'm too cheap to buy tires! |

Looks like an IB without the frame rails to me. But I am no expert when it comes to Bs. ------------- '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 |

Look on what used to be the top of the left axle housing for a SN. Compare it with my B shop manual and my military B manual. http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf" rel="nofollow - http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf http://geraldj.networkiowa.com/Trees/BMilitary.pdf" rel="nofollow - http://geraldj.networkiowa.com/Trees/BMilitary.pdf There might be an IB manual at http://www.grandpastractor.com" rel="nofollow - http://www.grandpastractor.com in the AC tractor forum. There might be a B operator's manual there too, or on epay. Gerald J. |

Like you said, it is really done very tastefully, very cleanly. I've never seen one like it. Who ever did it did a great job. I wonder if it was by a municipality for just a mover tractor? ------------- "Allis-Express" 19?? WC / 1941 C / 1952 CA / 1956 WD45 / 1957 WD45 / 1958 D-17 |

| I like the fab work. The person or shop converting it had the use of good metal working equipment. It looks to have the standard torque tube rather than the short IB torque tube. The holes in the steering wheel post shows it was not factory design was a but a conversion. |

I would call that a "professionally revised B". That doesn't look like it was done by a do-it-yourselfer. Probably built for a Municipality for a specific purpose. Look closely at the diamond plate work and especially the hand brake controls. That's pro built if I ever seen it. If it isn't pro built, someone has access to a nice pro fab shop where they can fab pretty much anything they want. I agree with Ted. Nicely done!! Congrat's on your purchase Jimmy!

I have to agree that it was probably made for a special chore in a municipality. Also, as stated above the modifications are very professionally done. In fact the very first IB's - if I remember correctly - did not have the i beams. I can still remember the pictures of the specially built B's with cranes on the front to go into box cars for unloading. Looks good. Take good care of my favorite. Good Luck! Bill Lonb |

| It is an early 1, no place for a Genny, SSN shows it to be a 39 or 1940 if I crossed it right. |

Judging by the build quality and the color, I'd wager that it was either done by a Product Development department of either AC, or WOODS... somebody that wanted to not only prove the viability of the setup, but also test the viability of a market. IF it were just a one-off to test for functionality, they would NOT have gone through the trouble to make the nice footwell radius bends and match the curves of the torque tube. The setup here is yeah, a little 'cubbish', but there's absolutely NO comparison to the cub with respect to power... even with two spark plugs out, the B will stomp the IH flathead c60... probably even keep up with it missing three. This ISN'T an aircraft tug... at least, not if it were fitted up as seen here- no ballast on the wheels. The PTO thing is intriguing... if it was a municipal, highway, or fairway mower, it'd have SOME kind of clutching mechanism for the deck. Did the deck, or the PTO connection point... have a disengagement system? Perhaps that big disky-looking thing was actually the back side of a multi-plate clutch, so it could be thrown in and out without stopping? If so, that'd be downright cool. ------------- Ten Amendments, Ten Commandments, and one Golden Rule solve most every problem. Citrus hand-cleaner with Pumice does the rest. |
