ACCO Super Grader
The Acco Grader was powered by two engines. A 1000 horse power engine was in the rear part of the grader whilst a smaller 700 horse power engine was at the front. These engines gave a combined power output of 1700 horse power. 1700 horse power was required too, when considering the Acco Grader weighed in at one hundred and sixty tons! The grader was initially built for export to Libya, similar to the Acco Dozer of the same company. However, due to trading restrictions with Libya at that time, the grader was never shipped out and remained in Italy.
