ABSTRACT:
First and second tractors are connected by a coupling device in a first row, and a third tractor is disposed in substantially parallel relation thereto in a juxtaposed second row. An implement assembly is connected to one of the first and second tractors and to the third tractor for moving material obliquely away from the normal longitudinal direction of working movement of the tractors. Preferably, a second implement assembly is connected to the other one of the first and second tractors and to the third tractor for similar operation when the triple tractor assembly travels in a reverse direction as a unit.
