I know nothing about the Toro models so every time this comes up I go looking for info. This time I am recording what I find so I don't have to do it again.
So far have found 23 models 1967-71
They used B&S, Tecumseh and Kohler engines
Recoil and electric start
Both vertical crankshaft and horizontal
7, 8, 10 and 12hp
3-speed and 4-speed Peerless gear transmissions and Eaton 6 hydro
I am posting what I find in a Database Table here
http://groups.yahoo.com/group/wheelhorsetractormanuals/
named
Wheel Horse Manual Location & Index "WHAT'S WHERE" for download
(Don't try printing this table because it is well over 1000 pages)
Do a search for Tractor Toro and they will come up.
Will keep adding to it as time permits so check back for more.
The MPV is Toro's Master Parts Viewer which is here.
https://lookup3.toro.com/partdex/index.cfm?xCaller=Toro
IPL is illustrated parts list
Will eventually go here
https://lookup3.toro.com/request/request.cfm
because I know some of the operator manuals can be downloaded. They will be listed also.
If anyone can add to this please do.
If I remember correctly Toro purchased the Springfield line and these are a continuation of that product.
