I've got a Cub 1861- (the one with the kohler magnum18 hp...). It's a project that I've been tinkering with in my spare time..... Tractor is somewhat beat up, but would make a good basic worker, nothing beyond that.
ANYWAY.... motor was pretty worn out - on the fence about rebuilding it given the cost of m18 parts. And don't want to invest in putting a newer v twin in it - its basically fix it up and sell it to one of the neighbors as a worker/grass cutter, part it out, or spend the money to go through the magnum and do it right - but not sure if the finished tractor would be worth the cost of the refurbish....
On to my question.... I've got several 16 hp k341's laying around. Thinking about dropping one of those in there. Anybody ever replaced a twin with a single like that?
The 341 is 2 hp down on the twin. But it's only pushing a 48" mower deck - My ford LGT165 basically doing the same thing with the thumper single and it has plenty of power.... More vibration, but at speed (this is a hydro tractor) the single evens out pretty well. The K engine may not last as long (theoretically), but is dirt cheap to rebuild if ever needed compared to the M twin!
I know the ignition wiring is different, but not a major deal. Adapting/lengthening the drive shaft should not be a problem either and the engine mounts on a plate, so easy to drill new holes to mount it. Compared to the twin, there is plenty of room for the little single, and height, while different is not an issue. My 341 has same type of electric clutch on it already so that should be no issue. Actually looks like the engine switch would be fairly easy, as these things go.....
I don't need this one, just trying to get it to utility status so I can find it a new home. And of course there would be full disclosure if it was sold - . So it CAN be done, but is it WORTH doing?
