Walk Behind Lawn Mowers

I just purchased a HU800AWD from Lowes. The box, as well as the mower deck, is labeled as having a 3 year limited warranty. However, the registration confirmation that I received (#130805-003067) shows only a 2 year warranty. The HU800AWD Operator Manual shows an * for the engine warranty which is clarified in the Honda GCV 190 owners manual for the engine to be 24 months. Since there was no disclaimer on the box that the engine was not warranted for 3 years, it would appear that either false advertising and/or "bait and switch" tactics are being used. Please provide me with documentation reflecting a 3 year warranty on the engine as well as non-expendables components.
