Hello everyone. I joined this forum last month and have enjoyed reading all the posts and comments, particularly on deciding what make and model to choose when buying a new lawn tractor. I bought a new Hustler 52-inch Raptor last year with a kawasaki 23 HP engine. No problems. The biggest factor for me in buying it was the engine. There are dozens of of manufactuers to choose from, all running the same engines from 4 or 5 manufactures. What irks me is that some companies, who once had a respected brand name, are now installing cheap, inferior engines in their residential models. I suppose that is a trend nowadays in other industries as well. To my knowledge, there are currently no manufactuers in the U.S. who build both the engines and the machines they power. Every summer, I see the old man down the street riding his 60's era Yamaha. He knew what he was doing when he bought it.
Murray is an oddball though. Briggs owns Murray, but they are manufactured by MTD and Husqvarna, but are required to use Briggs engines.
Again a sign of rampant consumerism and the unrealisic demand of the modern consummer that every thing they want has to be cheaper and magically get cheaper every year.
Stop for a few seconds and imagne jus how much work goes into manking an engine, it aint cheap.
The only real difference beteen a motorcycle engine & a mower engine is a gearbox & clutch.
Yet we will happily pay $ 20,000 for the imige of our wild & rebellious self sitting on top of a Harley which never gets ridden but quib at paying a reasonable price for an engine to go into our mowers that we use every week.
Mower companies do not like fitting imported engine into their mowers. It adds a lot problems .
They have no choice becaue you will go out and buy the cheapest mower in the class.
The engine is nearly 1/2 the price of making the mower so we get what we deserive for our cheapness, foreign made engine with no parts back up or support and once out of warantee, tough luck.
probably not the best comparrison but I have done a few Briggs motors for racers that will happily do 7000 rpm.
Once you take the counter weight off and balance the crank, there is not all that much difference.
Latter engines will toss the piston if you don't fit a stronger rod however the earlier side bangers will usually take 7000.
Thanks Motoman. Kawasaki has an assembly plant in Missouri where they build FS, FR, and FX series engines. I've never owned a Kawasaki engine before in any machine so I thought I'd give it a try. Just a side note here and being an average homeowner with a one acre plus yard to mow, the best engine for my money in a rider is in my old 89' Honda 3011H which I still use.
I have a friend who races go carts and gets two racing seasons out of a Chinese Harbor Freight engine. All he dose is remove the governor. He never wins but has a lot of fun without spending big money. Maybe the person using the Briggs engine wins???

[Q UOTE=reynoldston;227223]Being on the repair side of lawn mower engines Kawasaki would be one of my last choices of engines. Not that they are any worst or any better, I find the replacement parts for repairs are way overpriced. But also you know what you are going to buy so this really doesn't mean anything.

$10,000 for an engine ?To get back to the point I did not make as well as I could have.
From the factory's point of view they both have to make a crankcase which has to be cast and machines,
They both have to make a crankshaft to take 2 con rods
They both have to cast a pair of barels out of alloy and insert an iron linner into each barrel which must be bored to a precise size
The both have to make a camshaft
They both have to make an oil pump
They both have to cast heads , fit valve seats, valve guides valves , springs & rockers.
So from a manufacturers perspective their is very little cost diffrence between a mower engine and a motorcycle engine.
In the early days a lot of motorcycle engine makers sold a slightly modified version of their motorcycle engine as a stationary engine
Same tooling same precision, detachable barrels add a small extra cost to your HD but not that much extra cost.
I would seriously doubt if the cost difference in manufacture of the two was much more than around 10% ( gearbox & clutch excluded )
However the mower company would be running at a gross profit margin in the teens while the motorcycle engine sells for so much the gross profit would be around 50%-75% mark.
And ths is because Joe Public will happily pay $ 10,000 for and engine for their bikes while they will quib at paying $ 1,000 for their mower engines,
So a small engine maker can not survive thus the lack of makers.
My paid considerably more for my zero turn than my street bike cost new.$10,000 for an engine ?
A lot of bikes don't even cost that much.
I bought my twin cylinder, liguid cooled street bike brand new for under $7,000.
