Walk Behind Lawn Mowers

Hi, I purchased a walk behind lawn mower at Lowe's in Gadsden Alabama on April 1, 2016. I have cut my yard 3 or 4 time with it and this passed Sunday the belt broke. I can't find my paper work or receipt for the mower. The serial number is 1602166408132. It is model LC 221A 625EX. Lowe's has been no help so far. What warranty do I have with this? I love the mower but not pleased that it is already unuseable. Please help!
Thanks you,
