Hi,
I am new to this forum and have just obtained a 6U series D4 Serial number is 6U8564. This plate is on the engine and the frame plate is missing. I wonder if the engine has been changed at some time. It was origionally a side tank model and early in it's life, a custom made seat tank was fitted to give extre fuel capacity and a Cat dry type air filter fitted.

Does anyone know of other detail that could identify the age of the tractor?

Welcome Aussie John
My user name will give you a fair clue about where I am in Aus. The green grass in your photos puts you a long way from me I suspect.
D4 6U8564 is 1953 production. You should find a matching number stamped on the rear of the tractor but it may be buried in paint.

Look above the left cover on the rear of the tranny for 4 small holes or broken rivets. Usually the s/n was stamped there before the tag was put on. You might have to scratch some paint off but that's where the numbers ought to be.

Another welcome to you Aussie John , Our Numbers are increasing all the time ,Those are neat mods to your machine , Must have been used for farming to require more Fuel Capacity . This BB is a great source of help if you need it . I had a late 7U many years ago before buying a D7D17A which We still have . Good luck with Your Unit LJ

Hi Aussie John, nice unit. Those canopies seem to be common on Oz machines - were they intended for falling branches? Also, the cold start Lister looks like it's languishing a bit. They're really desired over here (U.S.) but the newer Lister fans end up with Listeroids, which are the Indian clones. My father has a 3 1/2 hp CS that he's had since new (about 50 years) and still uses frequently; all summer long on the 2 1/2 inch irrigation pump with at most 8 heads, and in autumn on the saw bench. I'm pretty sure he's never changed the oil in it ; ). He originally bought it from Levin and Co. as a lighting plant for the old homestead. Still has the generator but that's now hooked up to a Norman engine, which used to be in his uncle's hand-built boat (the list goes on and on and on.... : )
Cheers,
Neil.

Hi Neil,
The only photo taken at home was the unloading. The others were taken where I inspected the tractor out on the Darling Downs south of Dalby. I am located in the Toowoomba area.

Most dozers here were fitted with bush canopies and many also had down bars from the front of the roof down to the radiator and heavy mesh on the sides to give protection when clearing bush for farming.

I found the 4 rivets, now have to buff the paint back to look for the stamped numbers

Regards to all and thanks for your help,
John

Hi, Aussie John.
Nice catch and it looks in reasonably good condition. Somebody put a LOT of work into that fuel tank and also into the canopy. Way too many canopies were made with little or no overhang at the back to protect the operator from objects sneaking up - or down - from behind while he/she was looking up front.

Unless I miss my guess, it also had a tree pusher going by the risers just in front of the blade lift links.

If it is the original engine, the serial numbers should match. If they don't, it's likely been re-donked at some time. A rotary wire buff should do the job nicely.

Toowoomba, huh? I'm just down the hill a bit from you (in DowNunder terms of distance) at Cedar Creek, just South of Beenleigh.

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

Hi Aussie John,

Read my signature block. It looks like our 6U's are only 134 units apart on the assembly line, with mine being a slightly older cousin. 😆 Nice find!

Looking at the ACMOC Serial number book I once calculated that my 6U has a Febaruary or March 1953 birthdate within weeks of my own B-Day! Perhaps yours has a March or April Birthday. 1953 was a great year, if you ask me! LOL.👍

You can work out the exact day your old Cat was built when you find the casting letters, I'm working on a D4 7J right now and under the engine sump you will find several letters which tell me it was built on June 4th, 1940 if I got the code in the right order. Use the letters you see below to find the date your tractor was built, it is simple, N is 1, U is 2, M is 3, and so on, while D is zero, does that make sense? For you Aussie, Kiwi's and non North American members just remember the Yanks put the month before the day, so June 4th 1940 will read 6 4 40, where as we would write 4 6 40

I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
