Interesting, Joe. If it maintained that torque of 4.5 lb ft up to its maximum speed of 3,000 rpm (which it wouldn't of course) it would be 2.6 hp. That thing is too puny to run an 18" push mower, unless you mow every week to keep the grass short and the power requirement down. Maybe you could use it for one of those central Australian golf courses, made up of bare earth except for the black tar "greens".
