Why do you need to know this? If you have the model number that's all you need for getting parts. What does the year have to do with anything? Another thing. You are looking at two organizations here. MTD (under the Remington brand) put's the machine together - that's their year. The engine from Briggs could have been built 5 years earlier for all you know. So, once again, what does the year have to do with anything?
Well, I need the date of manufacture for a couple of reasons. First, there are some parts that are different based on the year of manufacture. That is really evident in the carburetors, for one. I needed to be sure I had the correct model year. So far, I haven't needed to order any parts that require knowing the year, but I didn't know that when I first started working on this thing. Secondly, I am refurbishing these mowers to resell to local people. A mower that is 8, 10, or more years old doesn't profit from knowing the year. However, a mower that is KNOWN to be a one or two year old model garners greater interest from potential buyers. The average Joe doesn't really know the difference between make and model of the mower OR the engine, but he DOES know that a 1 year old mower should be a good one. Never mind that the truth might be that a 1 year old mower could have been abused and beaten to death. All Joe sees is the fact that it is a 1 year old mower.
And I am fully and completely aware of the fact that MTD built the mower using a Briggs engine. I had a small engine repair shop for several years while I still operated my computer business. Working on small engines allowed me to decompress from sitting and string into a computer monitor all day. So, this ain't my first rodeo.
Finally, the engine was built on the 23rd day of October, 2021. That data is stamped on the engine case. I mentioned in an earlier post that the mower is probably a 2022 model since the engine wasn't produce until October of 2021. And, once again, I'm fully aware that finished products using engines manufactured by other companies might very well be a different model year than the engine. And again, this ain't my first rodeo.
