Just purchased a used Cub Tank that looked really great when I got it. After mowing a few hours obviously doesn't look quite as pretty! Will I do any harm to my ZTR by pulling over to my garden hose and washing her off to clean grass clippings?? I would think I should let the engine cool off for abit before spraying that, but is there anything I can hurt just by spraying water all over?? And once the engine cools off, is there any damage I can do by cleaning that also?? Just don't want to do any damage to anything so if there's something I should not spray or clean please let me know!! Thanks!!
