Question:
Is the HU725AWDEX 163cc under-powered as I see that your HU800AWD engine is 190cc and both have 4 wheel drive? I like the key start but don't want an underpowered engine.
Answer:
Ralph, I wouldn't say the 163cc engine is under-powered, as most walk behind mowers use a 160 - 190 cc engine. The HU725AWDEX is about 8 lbs. lighter as well.
