The abbreviations mean overhead valve and overhead cam respectively. I don’t know about the power difference. To sharpen the blade properly, take it to a lawnmower repair shop. You can take it off the mower first, or just take the whole mower in. The blade needs “balanced” sharpening so that the masses on both sides of the center are equal, otherwise the rotating blade will cause the whole mower to vibrate, and damage could be the result.

I Just looked it up on Wikipedia and OHV stands for Overhead Valve Engine and OHC stands for Overhead camsshaft.
Does this help?

Ohv=overhead valves operated by the cam from below
Ohc=overhead cam operating valves below it
Ultimately, horsepower is dependant on many other design factors. Sharpening varies dependant upon the cutter style, either rotary or reel-type. General rule of thumb is to simply re-edge the factory bevel-use a diamond file with slow, deliberate strokes, removing the least amt. of metal while providing a fresh cutting edge.
Good Luck!

Those have nothing to do with power or quiet. A 5 hp OHV or a 5hp OHC..both are 5hp….it’s which one has a better muffler. Now as far as sharpening the blade. I usually take the blade off the mower…..you can use a file or grinder….it doesn’t make that much difference. As mentioned already…don’t take off too much…also I bought a little balance tool…so when you file a blade down on one side…you need to take off the same amount of weight on other end. A better balanced blade will cut smoother and last longer…also keeps the motor running smoother. You can find balance tool at hardware store in mower parts section…about $4.
