| Hi all just reading a book by Alan C King about the D 10 and D 12 and I can not see the difference between the two is there any other then 1/2 inch in height and length |

| They both had the HIGH/LOW trans as an OPTION and not in the early models. |

Only difference is the wider rear side pieces, I forget the correct part name, its the piece between the rear and final drive... ------------- Source: Babylon Bee. Sponsored by BRAWNDO, its got what you need! |

D-10 and D-12 are identical tractors except for the width. As was said before, the D-10 is a one row tractor and the D-12 which is 11.5" wider is a two row tractor. Early ones had a 138 cu.in. engine and NO live PTO. Later ones had the 149 cu.in. engine and independent live hydraulics and PTO. An optional high/low range transmission was available on the Series III models. ------------- Nothing is impossible if it is properly financed |

Look at the steering linkages at the front axle, left side. The d12 has more parts. Google up images of both and compare.

I have a '65 series 3 D-10 with the 2 speed gear box in front of the 4 speed transmission. It will do 16.25 mph. I like taking it on caravans. It is easy to load on my flat bed trailer I tow behind our class C motor home. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

Brian, you are correct on the steering linkage. D-12 has an extra pivot point to accommodate a wider front axle tread width setting ------------- Nothing is impossible if it is properly financed |

| Just so there's no misunderstanding about the optional 2-speed gearbox. It was an under-drive, not an over-drive. So none of the original 4-speeds are any faster, only slower. |

underdrive .. great,, that's what I'd like to have to run the 5' rototiller ! The D-14 is a tad too fast.... course I'd have t find a D-12 and build another shed to hide it.. ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

| I think if you compare the ground speeds, under-drive 1st gear in the D10/12 is the same as low side of 1st on a D14. |

You are right. I had assumed that it was over-drive, I had to dig out my manuals and check. Sixteen and two tenths mph is a pretty speed for the hp. Thanks, Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

| Awful purty there Charlie, have the twin to your D12 with the live pto and live hydraulics, though some swear they did not exist that early. |

The nose weight was an option, along with the grill guard. I have both, thanks to Snowman, He built both. Dusty ------------- 917 H, '48 G, '65 D-10 series III "Allis Express" |

Never drove one. With that gearshift shaft bent like that, do they shift OK? |

Yes, same gearshift as a D14/15 has. ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

Forgot to mention the Throttle is different as Allis went with a different brand than what it had before. One is push and one is pull. Makes for remembering fun when hopping on them ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

| 4th gear in a CA, D-10 or D-12 is definitely a road gear. I remember when I was a kid that our CA would run circles around the other tractors on the road when going farm to farm to cultivate. |

Those are great looking tractors!! I spent many summer days hauling tobacco with a D10.Perfect for the drag middles and smooth sailing from the fields to the tobacco barns. ------------- ‘42B,’45B,’48C,’51CA,’52CA,’69170,1935WC,1936WC,WD,WD Highcrop,WD45,WF,D10/14/15/17/19 It isn’t how you die.It’s what you live for.-Daniel Boone |
