How do i find the age of my tractor

Post by munga » Thu Jul 08, 2010 9:24 pm

I am new to this forum so any help would be appriciated.
I have just bought 2 david brown tractors from a farmer, both are 3 cylinders , 1 has an id plate on the rear arch so i know that is a 770 model, The other has a siezed crank but i cant find any ID numbers anywhere on it. There is no plate on the rear arch & no markings on the flat section to the rear of where the tool box is located. I want to apply for log books for both of them but currently dont know the reg numbers either. Any help would be much appriciated ,l i could post a picture if it helps

The first one has an 880 chassis (I nearly went by the bonnet - it's wrong!). The clue for me was the "hole" above and behind the starter motor - only on 880's. Also, the starter on 990's of that era are on the RH side.

I would suggest the second pic is of an 880 too - the hole is there again and the reductions look like 880 ones. Also note the chassis is waisted beside the engine - a 780 is straight from clutch to front "tombstone". The lack of an hydraulic oil filter on top of the LH rear axle suggests post 68 (or so) - there should be a big round filter under the gearbox.

Are there no numbers stamped into the engine block? Right hand side I think, towards the rear of the block. That would be above the tool box on mine.

John , sorry i did not explain before i posted the pictures, both pictures are of the same tractor , the second picture is after i stripped it down a little. I have not yet got the second one home yet. Sorry about that.
This is the tractor with the siezed crank although after stripping it down a set of big end shells should sort that out.
The numbers on the engine block are AD3 55A 16671 if that helps at all. Also i want to inspect the rear brakes, can i just unbolt the rear hubs & slide it all out with the half shafts attached, is the anything in the axle that can drop out of line if i do that.

16671 should be your engine serial number.
Make sure you wire up the diff lock to keep it permanently engaged if removing the reductions.
If you don't have a manual then have a look here at the Transmission pdf

I have just looked at the PDF you sent me , many thanks for all that , i got a long read ahead of me. That answers another question i had. The 770 i also bought had the rear brakes stripped apart by the farmer that used to own it but he could not get the half shafts back in. Is there an easy fix, i looked at it & the diff lock had not been wired up.
(I am glad i asked this question before i stripped this one apart)

Don`t you have to tie down the diff lock to engage it !!!!!!

I don't know. I have changed reductions but I never made that mistake. Hopefully someone else can say.

Edit:
Just had a search and found a mention of the same problem here. Members restoration/ DB 1200 restoration

My father told me he took out a reduction one time (before I can remember) without tying down the diff lock, eventually managed to line it up with a brush shaft.
