Hi, Folks.

Found this little jigger at the East Hills Antique Tractor Society EHATS - show at Hartley, South Australia, a couple of months ago and thort some might like ter see it.

The last photo, a bit 'shady', is of the two adjoining inboard sections of the final drive housings bolted together.

On another note, each time I selected a photo and 'opened' it to load it then clicked "Insert" to add it to the post, it added TWO Identical images.

I suspect that ADCO might still have some sorting out to do.

Just my 0.02.


You have a wonderful day. Best wishes. Deas Plant.

Hi, Folks.

Last batch of photos of this 'D4':

A spot of 'nostalgia' for Australian lovers of older International Harvester trucks - the 'new' cross member between the two tracks and supporting the engine is an old International ACCO 'butterbox' front axle modified to suit its new application.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

Thanks Deas. I always wondered about that 2+2 D4 or whatever the owner calls it. I wonder what inspired him to build it? Challenge?Too many cold beers? Boredom?

How do you start the right side of the pairing?

Thank you, JM

Hi, juiceman.

I did get to speak to the owner about it. He told me that he saw some photos of the 'Siamesed' D8s and thought that it

interrupted before I could ask many more questions. The owner had five machines at that show and a LOTTTA people clamouring for his attention. Helluva nice bloke who would help anybody who asked politely and so he gottta lottta calls for help.

There were also two of the only three Holt 45s to ever come to South Australia at that show. The third one was 'cannabalised' to get one of the other two running and complete again.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

Conversation Piece - quite a project without doubt. Interesting from what Deas photo's show, looks like it would be possible to have the transmissions in different gears, maybe the clutches were tied together but gears? How much fun would that be to have one running in 2nd and the other in 4th! There are a lot of issues that would have to be considered and addressed other than just blocking the final drive and "gluing' them together. Useful, I doubt it would be other than for a hobby and conversation. cts

Hi, cts.

I sorta got the impression from the owner that he only did it for interest's sake and for the challenge. You could also put 1 track in forward and 1 in reverse and use it for digging LARGE post holes - might hafta put a cuppla 'fins' underneath to move the dirt in the middle to the outsides or it would likely 'belly' itself. LOL.

Just my 0.02.

Well if this 2+2= D4 ever goes to the field my money is on Deas to get the most accomplished with it.

In the last 20 years I would guess about 10 time as many of the X+X = perfection ( in the builders minds ) tractors have been created as ever where in the 1940's to 1960's . A just completed tractor show in Rantoul Iowa that has area to plow. I watched on video what I would guess as many wheel tractors semi attached to each other as where ever used like that back in the day. But since I did not wonder the Midwest back then maybe it was more common than I think. As long as the builder had fun ..............what else matters.

Ray and Deas - you two are on target - what makes the owner happy and gather some enjoyment is the goal. Other opinions as to the sense of it means nothing. Invention and modifications are often born of necessity, meet the conditions of the job at hand. Farming really forced many of the manufactures to meet the needs, Holt/Best tried their methods and thus began the Caterpillar of today. -cts
