Yard-Man 12AV829C755 21-Inch 6.75 HP Briggs & Stratton Gas-Powered Mulch/Bag RWD Self-Propelled Lawn Mower

I brought this mower last week the first mower they sent me was the wrong model in the right box that was sent back the next mower was the same thing the picture shows a Variable Speed Rear Wheel Drive the one they sent me was the same as White Outdoor 21-Inch 190cc Briggs & Stratton Gas Powered Mulch/Bag Self Propelled Lawn Mower #12AV839S290 this a not a
Variable Speed so i kept this one they gave me a reduced price one other thing this mower has one bar to adjust all four wheels this is fine but there is a .750 difference from front to back i called the 1800# today 5-26-09 and i was told that the .750 difference is right i would think that the mower would only cut in the front and not the back and then i found out that this IS A 2005 MODEL the next time a buy a mower i will go to a store,Amazon should tell you that this is a 2005 model!!!!!!!!!!!
