Hi newlifemowers, the machine that you have there is a Lawn Cub, manufactured by Boundy Manufacturing...Click HERE
on a good score there mate!

Sadly...not mine..

Just one i saw on E-bay

Ah now I know what the exhaust is off on my outboard. Thanks.

I've seen the BMS Lawn Patrol before, and I myself have it's baby brother, the BMS Lawn Cub.

I did have a number of spares for the Lawn Patrol, sadly, I think they have all gone missing.

The engines are similar, and you might find some interesting info in THIS thread.

Hi Ty, and thanks for putting up the link to your original thread....I knew I had seen one on ODK somewhere but couldn't for the life of me think where!

It's a rather interesting engine, BMS used their own set up, a crank case magneto, the coil, stator, etc. are all contained in that little plastic nose cone on the engine.

With the Lawn Cub, the points are not, by memory they are up under the flywheel, however on the BMS Lawn Patrol, I believe you will find the points are pushrod driven from within the crank case, and are indeed contained under that nose.

Thanks for that Ty, that design appears to be years ahead of its time....as our friend on VM would say..."all very interesting"
Good info mate,

Is the larger one a lawn patrol, or lawn scout... I found this...

Hi Ty,
From research I have found that although it is perfectly reasonable to assume the Lawn Cub and Scout came before the Lawn Patrol, it isn't correct. The earliest Boundy mower ad we have found so far is for the Lawn Patrol in September 1954.

The first mowers were JAP powered, as in the ad shown in your post. What I think may have happened is that when they introduced the new models with their own engine, in 1956 (though that date needs to be confirmed.) they were named Lawn Cub and Lawn Scout.
The Patrol name then dropped until some time later, when it was re-instated.

Boundy magnetos were a great idea. You simply unclipped a cover at the front of the engine and there was the coil and breaker points. The down side was it didn't work in practice. Loose crankpins were a problem because there was no usual flywheel magneto. The crankshaft, instead of having steel webs, had alloy discs which incorporated the magneto magnets. The discs had to be non magnetic. Constant hammering on the crankpin loosened them in the alloy discs, and the engine would fail.
This information was researched by Eric Schulz.
Here's an ad from 1956......

Hmm, that is a rather interesting find, BMS pre-dates the BMS engine, it's not surprising, most company's do, and many never make their own engine, but as yet, I did not know this!

Hmm, I think I might do a bit more digging into BMS and find out what I can about when certain design elements appear.

Hello ODK members,

I'm new to this post but I am fascinated by John Boundy's drive.
Victa's Mervyn Richardson developed an Australian mower engine; but so did Boundy!

My research agrees with Deejay's extensive work.
What is not appreciated, though, is that Wiltshire Company capital probably saved
the design (remember Wiltshire 'Staysharp' Knives?).

I know the story is that BMS engines were flawed; but I suspect the later versions
were entirely reliable - but the myth lingers . . .

It was a lucky bit of research to find a personal recollection of Bob Davies who worked
for the Boundy Company in the late 1950s (see attached).

All very interesting.

Hmm, again, this seems to point to the Patrol being a later Idea, which combined with Darryl's above add, supports his theory that it instead simply was discontinued, and then later the name revived.

Overall, an interesting find...

When my mowers were stolen earlier this year, three I had separated were missed, My fathers VC-160, my N.O.S VC-160, and my Lawn Cub, I think it is time to have a good look inside it's engine!

Hi Jack,

Just doing some reading up on Boundy after picking up a Nock & Kirby mower this morning, in his memoirs Bob Davies mentions Kelvin Grove. Was the Boundy Factory/Workshop located in Brisbane? Below is a pic of the mower I picked up this morning, original owner bought from N&K store in Blacktown.

Hi Paul
Yes, it appears that the Wiltshire warehouse and service facility was
somewhere in that area.

I have,finally, made a formal record of his memoir here:-
