gwest_ca-(File Mod) 11,246 #2 Posted April 14, 2020 All the Briggs engines Wheel Horse used have 1" diameter pto shafts. I don't know the length. Garry 1 Share this post Link to post Share on other sites
Shacker 4 #5 Posted April 14, 2020 Thanks guys, and here's a picture. Also have a plow for her, works great. My dad had a Wheel Horse in the early 90's, now it's my turn. Time to pull some stumps out! Was thinking about putting a pull start engine on it just for simplicity, which is why I needed to know which shaft size to start looking for.

gwest_ca-(File Mod) 11,246 #6 Posted April 14, 2020 The manual pto clutch on the B&S engines require a thrust bearing behind the engine pulley so you don't push the crankshaft out of the engine. You can see the bearing with the illustration of the engine in the parts manuals. Here is what we have identified being for the SB-421. They are in no particular order so look through them all. https://www.wheelhorseforum.com/search/?q=sb-421&quick=1&type=downloads_file Garry Share this post Link to post Share on other sites
