Is it possible to use another higher HP horizontal shaft engine on these little garden tractors?

If so, what has most people used?

I've seen a 460ci put into a Pinto. Anything is possible.

    If I can't do it slow then it's not going to get done.

Pharmer is correct. Anything is possible. This is a project that I am working on. JD 56 re-powered with an OHV 14 HP Briggs. The fit was tight but I think it will be worth the work. One thing to check is your blade tip speed (BTS). The formula I found is; BTS = Engine RPM X blade length X 0.262. The gov. mandated (ANSI) speed is 19,000 FPM or 200 MPH. Make sure that the pulley and drive system will handle the extra power. Mine is chain drive with a 3 speed tranny.

Yep, you can do what you want. 

Adapting a different power plant usually requires different belts, pulleys, etc. 

I have two xl10s.  Each is waiting to be repowered.  One will receive a 10hp Kohler, the other is getting a different but newer NOS Tecumseh.   Hopefully, once positioned they will only require a different length belt. And some new wiring/ignition switch.

Go for it.    Rick

The attached Tecumseh manual has engine specs including physical dimensions for 2 to 18 HP engines.

Maybe you can start there?

Good luck,
