My son and I are restoring an early B-10, how can I
tell the year it was manufactured?
Tractor: S/N 019953
Engine: S/N 38361

Thanks Scott

Be careful dating a tractor -- they're always looking for a commitment and a long-term relationship!!!

Seriously, there are quite a few old posts on the forum about different ways to find out the date of your tractor. The basic problem is that Simplicity did not use "clear model years" like we think of when talking about cars. They used "production runs" where a given model could cross several years without any significant changes.

Since this is a "Frequently Asked Question" I'll "use yours as an example" and try to provide a broader answer....

First, try searching using the "Search All Messages" function on the top of the list, finding "year" in the Message Body. For example, Jack Lindstrom (JackL or happyjack) has described where to find the dates on the transmission/rearend.

Second, the serial number of the tractor is not of much value -- we need the Manufacturer Number (Mfr No) for Simplicity or Product Number for Allis-Chalmers. Then, more than likely we can find it in the Model X-Reference Table. In your case, Scott, the early B-10s were Product Number 2025041 (Electric Start) or 2025042 (Manual Start) and manufactured in 1963 and 1964.

Third, the engine MAY be an indicator, if it is the original engine. Note that the date of the engine may pre-date the manufacture date of the tractor by several months, as they used up inventory of engines on hand. Again, there's several posts that talk about dating the Briggs engine. Later ones actually have the date of manufacture listed just after the serial number, if you know how to "decode it." There's a link on the Links page, also, that helps date OLD, OLD Briggs engines named "Technical Data for Old Briggs & Stratton Engines"

Hope all this helps. And, Scott -- I hope you don't think I've "picked on you" by taking this opportunity to answer a recurring question. I don't mean to....

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time
