ConsiderationsBefore purchasing a vertical shaft engine ensure it fits your mower by checking the following:

• Bolt Pattern: Verify the schematic of the bolt pattern. This engine is compatible with the bolt pattern of certain brands but the bolt holes may require thread tapping.
• Output Shaft Size: The output shaft size is 1 inch (25.4mm). Most ride-on mower engines with horsepower ratings between 10 to 18 hp have 1-inch shafts but confirm this matches your mower.
• Engine Displacement: The new engine’s displacement should not be less than your current engine to prevent underpower issues.
• Physical Size: If your mower has limited space for the engine check the physical dimensions carefully before purchasing. Refer to the images for detailed dimensions.
