I-400

I would appreciate any info on this machine. It has a 149 gas engine with a updraft zenith carb. It has a bucket on the front, but no backhoe attachment. This machine has a homemade counter weight on the back of it that was on it when I got it at least 10 years back. This allows the machine to lift more than I could ever attach to it. Mechanically this machine is strong. Maybe new brakes shoes,a rust free fuel tank and a tune up, but starts up and runs faithfully. However it is a very ugly beast. No fenders a huge counter weight, rusted bucket and just a eye sore in general. With all this I was wondering should I give the old girl a makeover. What is she worth fixed up and is the cosmetic parts available? I don't need her for work any more but would like to fix her up build a trailer for her and take the kids for a ride every once in awhile. Also I need to make a new bucket for her where can I find the exact specs for the original bucket. I can built, but I am unsure if the bucket is original. Thanks for any advice at all or any comments. I am very new to this restoration thing, but I have mechanical and welding background so I am sure I can duplicate it if I could get the info on it. Also what color is it suppose to be it has been repainted Cat yellow. Thanks again

A little info
I400

Probably one of the Allis Chalmers yellows listed. Probably won't matter too much since it is not going to be a show and parade tractor.
Paint

Look here for the serial number.
Email me the number and include any letter prefixes.
Serial number

As to value, it will be similar to a d-10/12 series III somewhere between $3500-6000.

Thanks for info. The d10/12 series III? Does that mean the fenders, side panels, etc.. from the d10/12 are the same as the I-400? As for the paint I would like to have it somewhat the same color as original. I mean there is alot of shades of yellow and those numbers don't tell you the differences, years or even the shades. I don't even know what shade it is suppose to be in the first place. Right now it is a "cat" yellow is that close to the original color? Again thanks for the info btw The tractor was made in 1967. Thanks again

The I-400 had three transmission options. Standard 1-4, R, Hi-Low Range 1-8, R,R, and the Reverser 1-4 Foward, 1-4 Reverse. If your I-400 has the Hi-Low Range it a little more sought after and if has a PTO. The Reverser was a poor design and very weak. Show me a I-400 that has the reverser option and I will show you a tractor that jumps out of gear or will start to jump out of gear.. You can also use a D-15 Series II fender for a D10 Series III or D12 Series III. The difference between D15 Series II fender and the D-10 Series III, D-12 Series III fender is a small cut was made to the lower back part of the fender for the top link bar that runs across. The cut to the should be 4 inches by 3 inches. I believe.. I have three I-400's and I'am in the process of coverting one from the reverser to the HI/Low Range in one them which has the loader and backhoe. They are great little tractor.

do you know anything about an i400 that wont go into reverse
