I have a John Deere weather enclosure ( 438751_weather_enclosure_642x462) that I use on my X 300. This is the 2nd winter I have used it. During the most resent cold spell the front 'plastic' panel cracked up the middle due to cold weather. I would have thought that cold weather ( not extreme) it was about 24 F, would have been considered in the design. Does anyone know of a repair for this?
