24.5 HP V-twin Toro zero turn engine with 1 inch shaft. It comes complete with carburetor and starter and engine harness, it may need the carbs cleaned since it has been sitting. There are no oil leaks, a very clean engine with low hours. I dont know the hours so dont ask. It has a built in oil drain hose. This will fit any zero turn I do have both left and right transmissions for a Toro zero turn which may fit other models and brands, you will have to research that. The deck rusted out and was no good. If you need the engine then set up a time to pick it up.
