Go to SEARS website, click on PARTS tab, type in your model no (upper right corner), click search.
Here you can search by part description, or better yet, pick a subcomponent and this will show a picture of the disassembled parts as well as give all the individual parts descriptions and part numbers.
OR - you can type "manual" in the part description, and this should take you to a page to order an owners manual for that tractor (about $10).
Hope this helps.
