I recently purchased my first walk behind mower (used.) It is a 12.5 HP 36" Toro t-bar. I mowed my first lawn with it this week and i gotta admit, it whooped me. I kept poppin wheelies with it and gettin into corners and stuff. And i know this is horrible and i greatly apoligize to Topsites, but i shifted it. Anyways i was just wondering how long it took you to get use to something like this when you started.
