hey guys maybe some of you can tell me what series this briggs is... all the id tags on my tactor are gone. my dad has had this tractor before i was born and he told me he got it from his boss with no ID tags. i finally found out what kind of tractor i have now i need to find out more about this engine.. heres a link to photobucket. you can see some pics of the engine. thx guys :)


Most B&S engines of that style had a model, type, and code number stamped into the sheetmetal flywheel shroud. ....The location of these numbers changed thru the years. ....The numbers could be on the front surface above the flywheel opening, on the top flat part near the sparkplug, or on the carburetor side of the shroud (aka blower housing) either on the upper flat portion or the lower curved portion.

Your tractor is a Bolens model 900 or a Bolens model 1000. ...The 900's were produced in 1964 & 1965. ....The 1000's were a 1965 model.

thanks for the reply, i only checked the front of the motor near the spark plug and it looked like some kind of ID tag was there at some point... but was ripped off.. ill still look around the motor thanks for the tips. oh ya btw Dr Bolens told me that its a 1000. were 1000's only made in 1965?? or from 1965 to another year

just did a little research and im pretty sure the 1000 was only made in 1965. just like you said. does that mean the 1000 is pretty rare?

The 1000 is not a rare model, but was only made in 1965

I have a 6B-HS  (I think that's what it said/ it's dark out and I have no lights in the shed)  alum vertical engine on a push mower.

slide choke, carb mounted to gas tank on right side (as standing on the mower handle end) and an oil bath air cleaner.

It has a model and type, don't remember if it had a code number (or serial as they were called on older engines) 

but it definitely don't follow the "standard" Briggs Model-type-code system that I'm used to on late 60s and newer engines...

if I had to guess I'd say this engine is probably late 1950's vintage.  I'll post the numbers tomorrow when I can get out there and see what I'm looking at

I know there are a batch of engines when Briggs first went to the 6 digit model numbers that show serial and type instead of a code. So far, there isn't a good way to date them.

The B&S 6BH and 6BH-S engines were manufactured may, 1953 until July, 1958.

 

They were essentially the same engine, the "S" suffix denotes these engines were equipped with suction carburetors.

 

As Doug said, there is info missing on these engines, and they had the Model-Type-Serial Numbers, not Model-Type-Code. 

 

You may be able to trace its year of manufacture through the mower brand if you know the model.

no its an old push mower that's been repainted. no ID present.

Left side wheels at the corners like we are all used to seeing, right rear at the corner, rt front behind the discharge chute like a typical Lawn boy deck looking thing/// but it is stamped steel not magnesium like the old LBs were...

Would March 1948 make sense?

Look for the model 14 section, then look up the serial number.  http://www.asecc.com/data/briggs/data4.html#14

No, the model 14's were cast-iron, while the 143000 models were aluminum.

 

The 143302 model engine was used on Bolens model 600 tractors in the 1962-63 years, so engine production was possibly late 1950's and early 1960's.

 

I was unable to locate any production dates at the asecc website, either.

The late 50s early 60 makes sense. Its on a 1959 David Bradley riding mower and I was told from the original owner that it was the original engine. I just like to double check everything....Ive been let astray before on purchases. Thank y'all very much stay warm.

From what I understand my number in my big ten briggs is 606675 the 606 makes it a 66 because you take out the second number an put the first and third together to get the year .
