I made a cheap grill cover for my 1538. The radiator cover still allowed snow to enter the grill and get to the battery and air intake. This should help with those issues and help maintain proper operating temps.
Worked the tractor for about 1.5hrs. Low 20°f and wind blowing 15-25mph. The tractor came up to temp in under 5' and never moved again. The motor, battery and air intake were clean and dry. I was pushing about an 8" storm.
