Something that has bothered me for a while is understanding the difference between the quoted Bolens model numbers and what is stamped on the tractor. For example, the 1054 I recently purchased is easy as it is stamped as 1054-03, which I believe means the third production run of the 1054.

 

However what does it mean if the suffix is missing, which is the case for at least three of my tractors. One of my G10's has just "1055", my HT23 just "2389" and my G12 just "1255"? When the suffix is missing, does that mean that it is the first production run as in -01?

 

Here is a picture of the tag on my G10.

I would be really interested in the view of the experts

Thanks

Iain

The first two numbers of the serial number is the production run of the tractor.  As in the 02 on the photo you posted is the producton run of your 1055.   Bolens changed to that serial number system in your photo in 1973.

Iain,

 

Here's a link to a service bulletin that explains the change:

Thanks guys that is really interesting and helpful, great stuff. Dave, many thanks for service bulletin. I am out of download quota today but will download it tomorrow.

 

Just to make sure, I have got this right:

 

- The serial number of my G12 is 101982 which makes it the 1982th tractor on the first production run

- The serial number of my HT23 is 100733 making it the 733th tractor on the first production run

- The G10 I posted with a serial number of 0200595 is the 595th of the 2nd run.

 

Any significance on the leading zero for the first two?

 

This then makes my G12 1976, my HT23 1980 and my G10 1975. The really interesting thing about this is that I dated the engine in the G10 as 1973 which means I either got it wrong, it sat on the shelve for a long time or it has had an engine change.

 

I am slowly filling in the gaps in information on my tractors, still a way to go.

 

Iain

You re close, but not quite right  :D

 

Bolens started the first SN with 00101, so you have to subtract 100 from your SN to get the proper number off the line.

 

For instance your G10 would have been the 459th off the line.

 

The leading zero is most likely there just in case they ever had more than 9 production runs,

Thanks Iain for raising this as I could not interpretate the # on my Bolens. I will now be looking at my Bolens # with new eyes.

Great stuff.
