I'm thinking about buying a Toro 54" Timecutter from Tractor Supply. Does anyone know if they are built cheaper for TS as I've learned that JD is for say Lowe's? Also, I've never used a o turn and looking online, it said not to mow over more than a 15 degree slope. I've been using my old JD145 to mow parallel along an approximate 25-30 degree slope. Thanks for any input.
