I bought a late model Simplicity Landlord with an 18 hp Vanguard vertical shaft engine in it. I need to replace this engine and want to swap a used engine engine in it if possible or maybe something new, but less expensive than the Vanguard.

The engine code is 35077
The engine type is 1152-E1
It is 18 hp, a V-twin, has a 1 inch diameter x 1-5/32 shaft.

I don't mind going down in hp for now and have found a free donor tractor (MTD) with a B & S 14.5 OHV I/C Quiet engine in it. I can't find the shaft length/diameter listed anywhere or what the alternator amperage is.

This engine code is 287707
The engine type is 0224-01

The Vanguard on my tractor has an alternator that is 16 amps, but I'm told a 9 amp will work. The tractor has an electric PTO and dash and head lights. For this swap, I can do without using the head lights if that will reduce the load on the alternator. I've also seen engines with 5/3 amp alternators - not sure what the design intent/use of that configuration.

So what to do? Can I use the above 14.5 engine or should I look else where?

Any advice would be greatly appreciated.

Thanks!
Bill

Engine should bolt up no problems. You likely will have to modify the wiring harness. Shaft should be the same. Electric PTOs do draw a fair bit if current. You will have to see what alternator is on the smaller engine.

Thanks much for the help. Any idea how much current these electric PTO's draw?

In doing some reading just last night, I discovered my Tecumseh snowblower engine has a 3A/5A alternator. 3A DC, 5A AC, I believe. The DC side is to charge the battery (if so equipped), and the AC side is to power headlights and handwarmers.

But that's probably a significantly smaller load than your electric PTO, I'd guess. So perhaps not a configuration that would really help you.
