I haven't seen the yanmar one, but the vast majority of engines designed for generator applications have a tapered crankshaft, and very few non generator attachments use that tapered shaft seat.
Most pumps and whatnot use a straight crankshaft with a keyway.
diesel engines are better in applications where they are going to be used under moderate to heavy load for extended periods of time. I don't know how long it takes you to feed/water the calves, but I'd say if it's less than about 20 minutes use at a time, then a gasoline engine is probably a better fit, as a diesel engine under light to moderate load might not even be up to operating temp for the first 10-15 minutes. Diesel is also harder to start in cold conditions compared to gasoline (just something to consider)

I have given it slot of though about putting a l100 on my old snow blower. It’s got a 7hp 1977 motor on it that needs a break. I think the l70ae would be fine but more power the better lol. I’ll see if I can get a picture of the old girl

Having a taper shaft isn’t a big deal either an adaptor or get a Daytona coupler I’ve modified one for a customer to run on a taper shaft. I’d go for it. If I get my hands on one before the winter I’ll throw it on. You could always buy a different crank from Yanmar. It’s not to bad to tear it out and replace it.

If I had money just laying around, I would order a Super Split log splitter, but use a Yanmar single lung for the powerplant instead of a gas job.
I've had the same curious thoughts, for the same reason. Passed a snowblower for sale in a driveway the other day, and went hmmmmmm that could be cool....
Aside from the tapered crankshaft, a couple other things to consider. Unless you want to pull start it, I don't believe the flywheel on it has a charging mag setup or VR, since the 831 is set up to charge from the PMA. And you'll either need 2 batteries or a 12V starter, unless you plan to slave it off of a MV, or pull start it.

You could always ask kloppk if he is going to make any more conversion kits. Look at my posts I just finished mine with a few other mods.

Yes, I'm still making them.
Per forum rules one can only have a few listings in the Classifieds section.

at 4-5 hours use a day, a diesel will definitely have the advantage over gasoline in everything but how loud it is.

Pull starting these isn't hard, at least in my experience. I have an L70 and a clone engine and they both pull start without too much fuss down to 30 degrees.
Send a link sometime.

Mep831a conversion time!!
Good morning to all. A while ago more like the begging of this year I picked up from kloppk a conversion kit to remove the inverter and use a standard generator head. I finally got around to it resting the Mecca alt s16w gen head. It showed up last night and nice and wrapped up. Over the next...

The decompression lever is a definite helpful feature!
I don't find the Yanmar hard to start. In cold weather, a extra few pulls to warm up the cylinder. Just go find one of the 125gpm pumps though vs converting a engine from a genset. Great little pumps.
The new Hatz engines/pumps are a better unit though. The Hatz engines are great.

Yanmar engines are bulletproof in my opinion....

Yeah there not bad. Well if you have an electric fuel pump. I did it to the mep831 and just cracked the line on the injector until I got fuel there and started it up. It took a few seconds then smoothed right out.
