The drive system has a traction hydraulic circuit having at least one hydraulic motor and at least one hydraulic pump. The circuit includes a first line region between a first connection fitting of the at least one hydraulic pump and a first connection fitting of each hydraulic motor to drive the at least one drive roller in a first rotatable direction and a second line region between a second connection fitting of the at least one hydraulic pump and a second connection fitting of each hydraulic motor to drive the at least one drive roller in a second, opposite rotatable direction. A valve assembly is provided with each line region for selectively interrupting and releasing a fluid flow connection between the at least one hydraulic pump and at least one hydraulic motor.

摘要： A compaction drum can include an outer surface defining a width. The compaction drum also can include a plurality of pads disposed on the outer surface of the compaction drum and positioned in at least one row. Each of the plurality of pads can be disposed circumferentially spaced apart relative to one another on the outer surface. Each of the plurality of pads can define a first height. The compaction drum further can include a plurality of ribs disposed on the outer surface. Each of the plurality of ribs can be connected between adjacent pads of the plurality of pads. Each of the plurality of ribs can define a second height. The second height of each of the plurality of ribs can be approximately equal to the first height of each of the plurality of pads.
