By going to our Public Website you'll find on the bottom of the page a link to Manuals. Look up your model number in the parts manuals. Please take note of your serial number because some kits have changes within Model number ranges. The mulch kit numbers would be found toward the back pages. You may need to order blades with the kit. With the limited numbers you have given me my guess would be 108563 and (3)794214 blades. Strongly suggest double checking these numbers with the manual and your units numbers.
