the power to the front wheel was done by a pulley on the recoil end of crank.. to change the belt I had to take the top tin off the engine.. then unbolt the recoil from the tin.. mine had the plastic hood & it was a bugger to get off.. had to remove the steerin wheel to do so..On a large dairy farm we mowed a LOT of grass with an older one like that. The last ones had that little hood and the tilted back steering wheel. The older ones had a steel hood, steering wheel shaft stood straight up. The mower deck was powered off of the lower end of the crankshaft, and the transmission was powered off of the upper end of the crankshaft. What I have read on the web is that the only engine they could get to work on that mower was no longer able to pass emissions so they stopped making them.
