Purchased knowing it had some engine problems. Found that dealer had re-ringed engine, but installed 77mm rings on 80mm bore engine. Installed correct rings, smoking/oil consumption ended. Charging problem, finally found it was missing ground strap for rectifier. I found out that some Kohlers came with plastic or steel engine shrouds.
I have a 50" deck and a 42" 2-stage blower for this. Used blower for the first time; very happy with the distance it throws snow.
