I have done some searches but cannot find my serial number or something that resembles a serial number. Please look at stamps that I got on the tractor and advise. Tx Werries
The serial number is located on a machined surface just above the manifold at the number 1 cylinder. It's stamped in, so you may need a scraper or some sandpaper to see it.
The numbers you have photographed are casting marks. The first picture does sort of look like a date giving an approximate year of 1966.
The casting code L28F on your transmission housing indicates it was cast on 28 September 1961. The tractor was probably assembled in the following month. To see whether the tractor is an original, or a "bitsa" look for this code on other major assemblies, such as the engine block, rear axle, hydraulic assembly and sometimes on the front axle. If they are all around the same date then your tractor is probably original, although in over 50 years, large parts could have been replaced from donor tractors. Your engine/serial number should be somewhere around 1619000 if it was a pneumatic governed fuel injection pump. If it has the later Simms Minimec fuel injection pump, it will be something like 08A-300001-M.
Thank you thats is valuable infom. The dates seem to be corresponding to what the farmer told me that his Dad purchased the tractor new in SA mid 62 to early 63. I have unfortunately not been out to look for the number as per Puffie's post. It has got the Simms Minimec so It will be interesting to see what the number is. Regards Werries
