In the late sixties I made a few visits to LA Delta Plantation which is between Jonesville, LA and the Red River. They were using a fleet of dozers with shearing blades to clear about 60,000 acres of hardwood forest. For the first tillage pass they used 80 - 100 HP farm tractors and about 20 AMCO disks to chop the debris. I quickly learned that a notched blade will chop debris better than a smooth blade. A smooth blade will outlast a notched blade because it will not wear as fast and is more resistant to splitting. An offset disk will ride over a stump or slide sideways when it bites into a stump. A tandem disk has opposed gangs. When a tandem disk gang digs into a stump the opposed gang will resist the disk sliding sideways. The disk will ride over the stump, the stump will break or the disk will break.
When I was working in Ghana, we were clearing brush and smaller trees. We’d run the dozers, let the locals pick up the wood, then pull 20 blade Rome offsets with 42” blades. These were normally pulled with a D-7H, an 8950 would struggle with it half open. After that an Amco 30’ tandem with 24” blades and rock flex gangs followed by a Landplane. |
