The layout of the new machine gives the driver far better vision than is possible with a conventional type of plough. in which the snow is thrown out ahead of the cab.
The new plough also incorporates a torque converter, a full-torque shifting transmission and a constant-engaged differential-output auxiliary transmission, thus the machine can travel at a continuous speed of 45 m.p.h. and is capable of ploughing at speeds of up to 30 m.p.h., removing snow at the rate of 2,200 tons
per hour, with an ejecting distance of up to 80 ft. in low gear and 110 ft. in high gear.
Known as the Snowblast Model R-2200 A, the plough has a Cummins NH-220 220-b.h.p diesel engine and four
wheel drive. The Robla plough is driven by a Cummins NRT0-6-IP 335-b.h.p. diesel, located amidships. The machine has an overall length of 32 ft. 6 in., and weighs approximately 17-I tons.Overall width is 8 ft. 6 in.
