The serie number is on left side motor near the poney transmission and on left side back stering cluch housing.
Thanks Gemdozer, left side by the pony is where I found the tractor number. I will have a look by the steering clutch housing to see what matches.
It'll be 2 weeks before I get a chance to go look though 😞
The number will start with 7U????? so if that nuber you found on engine stats with the 7U your tractor was built in 1948. Also I wouldnt part much into what a parts guys says most are too lave to do any lookingup they want you to do all the work and just give them a part no. and it is 4F7956
I forgot that number is good for every 7U-6U made
My D4 is 07U2777, That's not that far apart. Haven't got around to doing anything with the D4 yet, possibly this summer needs a little TLC & have to mount a blade ( 6 way ) have to find a few parts first & a winch. Well good luck & thought that I would say hello & happy yellow dreams.
That is the part no. for the fanbelt for all the D4 7Us and 6Us 4F7956
