Go to The Database and open the largest Table. Type a model number in the search box and then look down the results for your year or serial number. The service bulletins are listed with their number and file name. All the bulletins are in the Files of Group #8.http://groups.yahoo.com/group/wheelhors ... rmanuals8/
Membership in each Group is required.http://www.partstree.com/parts/
will also give you the illustrated parts lists for everything.
Type Toro in the 2nd box and a model number in the 3rd box. Then select your serial number from the results. The 1st didgit of the serial is the year - 4=1994. The parts that are still available from Toro are priced. These are the most accurate and easy to understand parts lists on the net.
You can get the same ipl's here but the parts lists are terrible and cause many ordering mistakes.https://lookup3.toro.com/partdex/index.cfm?xCaller=Toro
The good part is after a page opens you can click on a small printer icon at the top left of the illustration and the page will reload to one that prints well. These ipl's are shared by similar models so the same item may be listed 3 times but they fail to tell us what model uses what.
Adding - go here first in case some of the parts lists are available for download in one file.
The Toro manuals listed in the Database can be downloaded fromhttps://lookup3.toro.com/request/request.cfm
Enter a model number and the serial number.
There is a month's worth of reading there. Let us know if you have trouble getting it.
