Three times more efficient than the original Iseki PRJ8D rice planter.
Three times as much:
Planters (7.2 m working width) and saplings (72 m capacity)
increased the engine's output to 50 horsepower.
increased fuel capacity to 100 L, increased driving speed to 30 km/h, and increased dimensions to 4.2 m in length and 4 m in breadth.
The same as the first 8 km/h planting/working pace
