Well once again I'm stuck at home instead of going to the farm to work on the tractor. It's starting to tick me off a little but maybe tomorrow will work out better.
Anyway I'm looking to re-power the walking tractor with a different engine.
After watching some Youtube videos I think I've decided to use a 5 HP Tecumseh snowblower engine since it will fit under the hood without any modifications to the tin work.
My question has to do with the shaft size that is needed to power the tractor.
The engine I'm looking at has a 3/4" diameter keyed driveshaft that is 2-1/4" long. Is this pretty common for a DB engine and will it work with the sheave that I have on the 3 HP Briggs that is currently on the tractor?
The model that I've found is a FS50 which does have the air cleaner instead of the winter heating box around the carb. There is no way that I would ever run an engine without an air cleaner, even in the winter.
I've always been more of a Briggs man but I do have an 11 hp tecumseh on a generator that I've had since the late 1990's. I can still go out and start it at anytime with just a couple of pulls as long as I do the regular maintenance on the carb.
So, if you can help me out with this question I would greatly appreciate it.
