What is the machine that is used along the boards and resembles a lawn mower?
A. This machine is called an ice edger and it is used to help keep the ice sheet level. The ice resurfacer does not shave the ice any closer than 2-3 inches from the boards. This causes the ice to build up along this area. Also as the driver slows down in the corners, more water is deposited and the ice builds up higher in the corners. The purpose of the ice edger is to shave the ice about 6-8 inches from the boards, making a level surface. Then the left edge of the conditioner can rest on this surface and the thicker areas of the ice are shaved down by the resurfacer.
