    Ok there is a Toro push mower on sale (push, no bag, mulch) for $539.99 minus a $70 rebate. Its engine is 190CC. How do I compare that number to other mowers (and other Toros) with 6.5HP engines??

    Also, some mowers hace 6.25 lb/foot of torque on them. What does this mean?

    First, Why in the hell would you buy a push mower for 469.99

    To go from CC to Hp isn't really a easy thing to do it will never be a constant number. Different engines with the same CC can and often will produce different amounts of power. You can't convert directly between horsepower and engine volume becouse of the unknown variables between motors. Horsepower is not a funtion of cc displacement you are kinda asking a trick question.one horsepower equals 33,000 foot-pounds of work per minute — that is, the power necessary to lift a total of 33,000 lbs a distance of one foot in one minute. This value was adopted by James Watt in the late 18th century after experiments with strong dray horses and is actually about 50% more than the rate an average horse can sustain for a working day.

    The toro is about 6 hp but that is a guess
