Are tractor engines interchangeable?

[Dave Olley]

Hi
I am an english man in France, desperate for advice.
I have a ride on mower with a broken B&S motor.
I have a choice of Kawasaki, Tecumsah and Honda motors to use as replacements.
Will mounting bolt holes correspond
Are drive/PTO shafts of same diameter
What problems am I likely to encounter
Given the choice, which would you have. I am leaning toward the Honda
Thanks for any advice

Mounting bolts will be the same But crankshaft can vary by different length or diameter depending on engine. Also the exhaust will not interchange and the wiring maybe different.

Measure the PTO shaft carefully as both B & S and Honda made metric engines for the EU and they have 25mm shafts while US ones are 1"
