I picked up a 10343 a couple of weeks ago, which looked like it had not been used much. I cleaned out the carburetor and it ran really good. So, I put a mulch plate in and mulched the leaves in 2 yards and made a $100.00! I looked up the serial and model numbers and found that this outfit was called the "Green Machine" (this one has a black rather than green shroud) and was only made for one year - 1994. I presume that this 4 horse V series engine was made by Tecumseh, but I can't confirm that. Anybody know about this neat little mower????

From what I can see, it's a Briggs and Stratton, if it's this one here: https://www.partstree.com/parts/law...es-walk-behind-mower-1994-sn-4900001-4999999/

According to Lawn-Boy that number is a 2stroke.

Yeah. Both of the sites we posted lists the engine as a Briggs & Stratton 084232-0121-e1, a 2 cycle. I'm not sure when they stopped, but Briggs did make some 2 strokes. I wonder if yours has the original engine.

Guys,

I really appreciate your help. However, I never had any doubts that this is a 2-stroke! I am just curious as to why this model was only made one year.

Happy Thanksgiving To All!

Best I could tell, it was some deal between Briggs and Komatsu Zenoah that started in 1987, but "This venture was not successful, because the rising price of the yen made the engine too expensive in the U.S." (https://en.wikipedia.org/wiki/Briggs_&_Stratton)

Z,

Thanks for the information - very interesting. I'm sure that this is the original engine as the whole machine has not been used much. I may have stumbled onto a rare one!

Best Regards,

The V series engine is not really rare, used for many models in the mid 90s. It has the same rotating assembly as the OMC/Lawnboy F series engine, but has a slightly higher compression cylinder head. It was just Toro's cheaper version of the Lawnboy F series engine to be sold at the big box stores on the steel deck Lawnboys and Toros. A good, strong engine, but loctite on the hardware is a must if you want it to stay assembled. Just a note for those that may not know, but Lawnboy was bought out by Toro in 1989.

Very interesting.I've come in possession of a lawnboy mower myself.Model 10330,Serial #9903070.This mower was made in 1999.I knew Toro bought 'em out,but didn't know when.So if they bought them out in '89,why is this mower made in '99?

why is this mower made in '99?

Why not?
Lawn-Boy still exists...they just ain't what they used to be.
A couple of links posted incorrectly identify engines as Briggs & Stratton. Those are Briggs numbers but are the snow engines known as R*Tek and were never used on any lawnmower.
The 10343 is definitely a Toro/Lawn-Boy model V...not Tecumseh or Briggs.
As Lawnboy77 stated, it really is a disguised model F.
Some years ago I modified one for Gokart use.
