Graders

A trailer elevating grader has a poor manoeuvrability and it takes much time to turn the machine around at the end of each pass. Besides (кроме того), there must be another operator for maintaining the engine and controlling the knife and the conveyor.

A semi-trailer elevating grader is used together with a 100-horse power tractor. It also has the same disadvantages (недостатки) as a trailer elevating grader. But it is lighter and has a different construction. It does not have a front axle but rests on a tractor. The disk knife, the share arm and the conveyor are raised and lowered with the aid of hydraulic cylinders.
