Toro Wheelhorse with Kohler Magnum M12.5

[Saintgeorge]

Hi all

I destroyed my Toro Wheel Horse with Kohler M12.5 when it ran hot because of mice nest materials near the air intake. It was a workhorse cutting walking trails on my 100 acre farm in Ontario. Any ideas where to pick up either a good used replacement engine or an entire tractor?

Thanks

John
