Hello, I have a 2011 Ariens 42'' Hydro-tractor wit a Briggs and Straton 19.5 HP engine. For the past couple of months I felt like the mower wasn't going as fast as it should. I have a 2000 Craftsman with a 17 hp that was faster. Today the mower started right up but now will only go extremely slow and I can hear almost a dull screech or whine from the back of the mower. Any idea what this may be?

Post model & serial numbers from data plate or sticker on mower, remove deck & inspect drive belt & idler pulleys for replacement, use OEM Ariens parts.
