I just bought an MTD Yard Machine Mini cultivator..Mdl Y125 from Walmart. I tried to buy the additional warranty. But the clerk couldn't find the supporting information, or where it was actually offered with this item. It also did not come with an owners manual. I don't know how to operate it..mix the oil and gas, etc. without one. I'm hoping that you can help. I DO have my sales receipt..but there was no customer support where I bought it. Any help witll be appreciated. Thanx
