Baby Tractor Looking for an Engine..

[JTMachineDesign]

I was gifted a 60s era Sears garden tractor with a totally seized engine. It has a belt-driven 4 speed trans-axle.
I'd love to get it going from the grand kids to putt around with.. might even be able to pull the shaker-screen sand sifter I'm designing.
I'm not an originality nut so I'm not married to getting the old engine running, would be good with replacing it entirely BUT
the motor shaft is on the right... all the motors I've seen for sale in the 9hp +/- range have the shaft on the left.

Anyone know of an engine in the 9hp range with the shaft on the right?

(I did find an air-cooled single-cylinder Diesel engine with the shaft on the right but it was pricey - way cool though.)

Try harbor freight. They have several choices for motors. Havnt heard any negatives about the motors either.

Not sure about you shaft on the right statement, it appeared the actual out put shaft is same as all small motors, the shaft on the right or in front of cooling shroud is probably for belt drive for electric starter....Personally I would forget electric start and just go with recoil starter for grandkids and your putt around "thing"... If really married to electric concept you can probably have adapter made to put a pulley on flywheel side. Have you pulled side cover off and looked at shaft arrangement ?

Cheapest new motor is going to be at harbor freight.....

8 HP (3?1cc) OHV Horizontal Shaft Gas Engine EPA/CARB

6.5 HP (212cc) OHV Horizontal Shaft Gas Engine EPA

For kids toy I think the 6.5 HP would be more than adequate.

Tried there first.. I like their motors.. they turn the wrong way

Not a kids toy, but grandchilden will probably drive it.. I'll probably hookup the sand machine and have them drive it around.. I'm a grandpa that knows how to get something done while they're having fun

Think they can help you repower small tractor

ccw facing the shaft is normal. I don't see why they would make an engine with a reverse rotation, since it would be a very limited market for those, also, these are clones of Honda engines...

Its ok with me, you can call it anything you want.... But I think you analysis of engine rotation is flawed.... I have yet to see in my 75 years a one lungers that is anything other then clockwise rotation from flywheel side (counter clockwise from shaft side) ....

Once you get tractor running, show us your "sand machine"...

Back in the 70s I was camping on a socal beach and woke at 3am to the sound of an engine moving slowly. Curious, I got up to see what it was. There was a monster wheeled tractor creeping up and down the beach grooming the sand. It used a blade cutting through maybe an inch of the surface that was vibrating is such a way that the sand (and beertabs, ciggybutts, and various and sundy other non-sand items) worked it's way up to a screen that the sand would drop through and debris would continue to a catch bin.
Now I'm in the process of moving to my retirement home full time, that shares the Joshua Tree National Park's north border. It's a terraced acre of DG/Sandy soil. Left alone the place starts to get erosion lines, wind-blown desert debris, etc... hand raking gets old so, I thought I'd recreate that beach-groomer on a smaller scale. I tried a land-plane type of rig and that worked, but all the debris bits are still there..

That shroud is covering a belt drive the starter would most probably be a starter generator combo. A new electric start engine will have a built in dynamo generator and a Bendix to flywheel driven starter mounted on the side of the engine. it may or may not require a separate solid state voltage regulator some engines come with one mounted on the engine.
If it were me I would go with something in the 10 to 14 hp range gasoline or 8 to 11 hp diesel
