I rented a power rake today with a Honda engine. Damn thing kept cutting off so I called Home Depot and asked what's the deal. It seems Honda engines have a safety device...if you're on a slope, going side to side, the oil, of course will flow downhill in the engine. There's a sensor that causes the engine to die 'cause it thinks it has no or little oil. The cure is to go up and down the hill (slope) instead of side to side. Now my question is if push mower manufacturers for safety instruct us to cut side to side on hills or slopes, why would they make an engine that won't allow that? Also, twice as much work having to go up and down the hill instead of side to side. Damn, that's a long post, huh?
