Abstract
A snow removal machine propelled by crawler belts trained around drive wheels and driven wheels is provided. The snow removal machine has a scraper confronting the outer periphery of the driven wheel so as to remove snow adhering to and accumulating on the outer periphery during snow removing operation. It prevents increase in tension of the crawler belt due to the increased diameter of the driven wheel in appearance that might otherwise be caused by snow adhering to the outer periphery.
